Hi Abhinav,

You should try and understand the data management in DHIS2 and the
different modules.
See the demo here - http://apps.dhis2.org/demo

You can look at our existing Android mobile applications:
Data Capture for DHIS2 -
https://code.launchpad.net/~araz-abishov-gsoc/dhis2/dhis2-android-app
- Download
App https://play.google.com/store/apps/details?id=org.dhis2.mobilehl=en
Or smartphone interfaces - http://apps.dhis2.org/demo/mobile/
We also have JavaME apps. Project page is here :-
https://launchpad.net/dhis-mobile

Feel free to ask questions regarding any of these apps or places where you
get stuck.
In the meantime, before the application process starts, it will be good if
you could share your experiences of starting DHIS2 development... what are
the difficult parts, what are the challenges, what frameworks are difficult
to understand etc.
This will be useful to other students who are starting to be DHIS 2
developers.

Re: [Dhis2-devs] [GSOC 2014] Allow data entry from OpenDataKit / JSON enabled storage API

Hi Anum,

Welcome to the project. Thank you for your interest in DHIS 2 development.
While the student applications period is nearing, we'd like to see that
you've become comfortable with DHIS 2 development.
That means being able to build DHIS 2 using maven, using launchpad and
coding with eclipse.

OpenDataKit (ODK) http://opendatakit.org is a project that uses XForms
for form layout and sending data. It is an Android application that used by
different projects.
The goal of the project that you mention is interoperability with XForm
clients like ODK and other JavaROSA complaint client
You should try to understand the XForms format -
http://opendatakit.org/help/form-design/

Once you've understood the format, the next step would be to
generate/transform (XML transform) from our DHIS 2 XML
(DXF2)http://www.dhis2.org/doc/snapshot/en/user/html/ch28s06.htmlinto
XForms.
Once you are able to generate XForms, that should be opened in ODK and data
entry can be done. After data entry ODK posts the data to a DHIS 2 server
that is able to take the XForms and import it into the DHIS2 datavalues.

I realize that most of what I mentioned above is difficult to grasp... but
putting some efforts to understand the broader picture will help you
understand what needs to be done.

In the meantime, before the application process starts, it will be good if
you could share your experiences of starting DHIS2 development... what are
the difficult parts, what are the challenges, what frameworks are difficult
to understand etc.
This will be useful to other students who are starting to be DHIS 2
developers.

Re: [Dhis2-devs] GSOC: Android and HTML5 features (Project)

Hi Gaurav,

Thank you for your interest in DHIS 2.
Please read other emails that have been sent to GSoC students on the list.

You should start with building and deploying DHIS 2. Document and share
this on the list so other students starting out can find it useful.
Since you are interested in mobile apps packaged using Cordova, look at
some example projects that have done that in DHIS2.
Here are some links:
-
https://wiki.uio.no/mn/ifi/inf5750/index.php/Trust_us,_we%27re_Scientists!_Visualization/Description

-
https://wiki.uio.no/mn/ifi/inf5750/index.php/Mandalorians_Geolocation_data_entry

Get some good ideas and include them as part of the GSoC application.

Hello Team,

I am under-graduate planning to participate in GSOC 2014. I found this
project (Android and HTML5 features) very interesting and is keen to work
on this project as my GSOC project this summer. I want some initial help
and guide, so how Can I start now and what should be my intial steps, as I
want to start as soon as possible.

I am thinking of extending the mobile version, by using Apache Cordova for
developing a hybrid app. This way we will have same codebase for multiple
platform (Android, Windows, iOS etc.). The Idea of mine is to use AngularJs
+ IonicFramework to build a Hybrid Application. IonicFramework is
specifically made for app development using Cordova/Phonegap. It overcomes
many shortcoming of JQM (like slow behaviour and click/touch problem),
which mainly was used previously. With AngularJs we have power on routing
and various other features. I am currently working on two application using
this same framework. I have integrated Google Maps, geolocation API and
handled data using JSON request/response in one of this application.
Other than the client side languages, I have expirince of working in
JavaEE, PostgreSQL, Maven and Ant build Tools, Git and SVN and Eclipse.
Below are my linkedIn profile.
LinkedIn: http://in.linkedin.com/pub/gaurav-saini/37/687/254
I am really very excited to work on this project with this new framework
in scope. I have researched a lot before and found this perfect for modern
smart-phones.

Re: [Dhis2-devs] [GSoC 2014] Questions regarding Android and HTML5 features

Hi Bhargav,

Didnt miss it, just wanted to gather a few more students before replying :)
Please look at the other email to which I just replied. It has some example
apps that have been attempted. Some are rudimentary, but those were built
in 3 weeks. You've got 3 months!

DHIS2 has a number of features that still do not have a mobile interface.
The DHIS 2 dashboard is one such place... so a mobile dashboard will be
useful. A messaging (DHIS2 messages) mobile app will be useful. Also an app
that can share and comment on interpretations will be useful. You can also
come up with your own suggestions.

Do read the other emails, to see what you can do till the GSoC application

Re: [Dhis2-devs] [GSOC] Scriptable SMS parsing

Hi Mayank,

Welcome to the community.
I'm glad to hear that you've completed installation without any issues. I
hope you can help other students resolve issues that they come up with on
the mailing list.

As you might have already seen, DHIS 2 can connect with an SMS gateway.
This is the documentation page -
http://www.dhis2.org/doc/snapshot/en/user/html/ch24s05.html
Most of this work was done by a UiO Master student, Magnus Korvald.
If you've got some time read his thesis -
https://www.duo.uio.no/bitstream/handle/10852/37426/korvald_master.pdf?sequence=1

The goal of the project is to be able to read incoming SMS through a
scripting language. A user should be able to write rules and map incoming
text to DHIS2 data elements.
Your experience from natural language processing could be useful, since you
can give us ideas on how to improve SMS data detection.

Long and Peder Andreas will be able to tell you more, if you can come up
with more concrete suggestions.

Re: [Dhis2-devs] [GSoC 2014] Questions regarding Android and HTML5 features

Hi Germine,

Sharing requirements and user-interface mockups will be helpful to work in
teams.
If your work is going to be open-source, any GSoC student can work with
your codebase.
The rule for GSoC is that the student should be doing independent work,
such that the student's code can be verified to be their own.

The GSoC roadmap is 3-months and if you are looking to start implementation
in 2 weeks, it will be difficult to expect that from GSoC work.
The GSoC student will be able to use your work and build better solutions
based on your feedback.
This is our goal with student participation, such that they become better
community players.
You may also ask your 2 students to apply to the GSoC programme. We cant
guarantee slots, as we expect it to be highly competitive.

You may want to create blueprints in launchpad for a unit of work related
to the project.
 If you already have a project tracker (like github, JIRA etc.), we can
also use that.

Infact the , (comma) is meant to be used for this, as is mentioned here:

Also Spring docs suggest using commas -

 Only problem is that the , character is defined as reserved in the URL
 spec:

 http://www.ietf.org/rfc/rfc1738.txt p2.2

 and causes e.g. spring mvc to split the value into multiple query params.

 For analytics we use ; for delimiting, which is also reserved, but is at
 least not causing trouble with spring mvc.

 Would ; be okay? If so please write a blueprint.

Re: [Dhis2-devs] DHIS2 WSDL?

2013-11-27 Thread Saptarshi Purkayastha







DHIS2 provides a REST or REST-like interface over HTTP.
So with just those 4 obvious verbs, I dont see that we really need a WSDL.

To send data from an EHR to DHIS2, you should create a report within your EHR 
to match the reporting frequency, data elements + catcombos and add those as an 
XML dataValueSet
This is documented here - 
http://www.dhis2.org/doc/snapshot/en/user/html/ch25s09.html

You would probably need to exchange metadata before to get the UUIDs for the 
dataelements etc.
If this is fairly fixed, should be fairly easy... if it isn't fixed you should 
read the metadata using - 
http://www.dhis2.org/doc/snapshot/en/user/html/ch25s05.html
and then read from those and compare them with your EHR.

It can be quite challenging to make it work in the first pass... but if you 
come back with specific questions, once you start integrating, we can help you 
better.

Re: [Dhis2-devs] DHIS2 WSDL?

2013-11-27 Thread Saptarshi Purkayastha

Hi Murod,

Good to hear from you.
The standard way in which WSDL is used (atleast 2.0 in context of SOAP), is to 
describe the Service in terms of Endpoints, Binding, Interface, Operation and 
Types. 
Most of this is self-descriptive in REST paradigm and infact not recommended 
for RESTful services that should support HATEOAS. I know there is the WADL 
standard, but its a rarely used standard and doesn't have much to offer for 
well documented web services. 

So, I wouldn't imagine that the WSDL document will give metadata information. A 
WSDL document allows clients of web services to generate stubs surrounding the 
service.
Instead, I think an XForm or DHISReport template will represent the metadata 
information in a better way.

I agree its not 4 words!! But once Edwin and his team starts the integration 
process and comes back with specific questions, we can guide them better.

DHIS2 provides a REST or REST-like interface over HTTP.
So with just those 4 obvious verbs, I dont see that we really need a WSDL.

To send data from an EHR to DHIS2, you should create a report within your EHR 
to match the reporting frequency, data elements + catcombos and add those as an 
XML dataValueSet



This is documented here -

and then read from those and compare them with your EHR.

It can be quite challenging to make it work in the first pass... but if you

Re: [Dhis2-devs] Timestamp returning date in web api call for datavlaue set

2013-11-19 Thread Saptarshi Purkayastha

I feel it would be good as a full ISO 8601 string.
2013-11-19T14:01:54 with or without the timezone.

Surprisingly, in the call that I pasted in my last email, for 3 datavalue there 
is no timestamp attribute.
Also the link which Knut sent doesn't have timestamp attribute. It will be good 
if they are consistent and with timestamp.

I like the lastupdated name instead of timestamp. This also allows to follow-up 
if the values have been changed or not since the last time they were read.

So what do we want here, a full timestamp as in numbers, or a full ISO 8601

I'm not too happy with the name timestamp, but I guess that's minor..

Re: [Dhis2-devs] Web API - Search by id

Hi Jason,

I am not opposed to it really and think it would be a nice to have (just as
 it would to be able to search on any property of an object), but what is
 the real use case here?


The real use-case here is that in Custom Data Entry code, I want to make
some Web API calls.
I can easily get the ID on that page and most functionality for web
interface exposes only IDs. This includes the .action URLs that I want to
use through a DHIS2 app.

Re: [Dhis2-devs] Web API - Search by id

It is generally considered to be bad practice in the design of Web API or REST 
APIs that two URLs point to the same resources.
Also I would think that people who want to juggle between existing web 
functionality and Web API, would like to use internal IDs to get the UID and 
then use the UID for web API calls. This makes it more flexible to use and 
switch between the two IDs depending what functionality you want to use, either 
from core web interface (uses IDs) or Web API (uses UIDs)

It's just for convenience. If you make an app that looks up organisation units

 Hello Mobilars and Saptarshi,

Agreed with SOAP is now old fashioned, but we should remember one thing that 
DHIS2 development programme and its deployment is primarily focused on 
developing and under developed country to improve their Health, Nutrition and 
Population Sector Program and its primary diameter of development(but not 
radious of development) should be focused on Mother and Child Health (MCH) as 
well as Rehabilitation and Child Health (RCH) Programme only. I am sure in most 
of the developing and under developed countries from kids to their parents even 
house surgeon and clinical doctors still  they are using every day SOAP 
products to make their hands clean and jerms protected. 

But i am little bit surprised
 suspicious with Mobilars and Saptarshi, whether you both are using it or not 
in your day to day life, perhaps quite sure 100 % that Weivao and Alex both 
have started using it every day to make their hands clean and jirms protected. 

Agreed with Mobilars that SOAP is old fashioned now a days and there are so 
much new developments has been happened in this area, but still these days 
there are so many old fashioned concepts are being used in developing and under 
developed countries like long back Fat Man (FM) doped in Nagasaki detonation 
causes nuclear explosion and destroying so many lives, but now a days in so 
many metropolitan cities this FM concept are being used as doping melodious 
musics, news, game commentary various live saving advertisements and so many 
audio programmes to make ppl feel good and enjoy their every day life.  

So in short, i can say, adhering to the old fashioned ideas like SOAP/Knut and 
HTTP/Bob interfaces are
 not as bad as just quickly sticking with alpha release of REST type of several 
applied science products and  api's like examination controllers which are not 
even properly tested and pass user acceptance test for expected requirements. 
For mapping and searching single resource, i think no need to use url as  
co-ordinate geomatory type of concept with multiple url for finding and 
searching one resource kept in DHIS 2 deployed application, rather it should be 
more clear in requirement analysis that target object or resource is static, 
not moving projectile. I think in DHIS 2 application development program, 
resources are in web-apps deployed on web server and its more likely static 
some where at a particular instance of time frame not inside flying machine.

Agreed with Saptarshi, requirement is little tough to use SOAP in DHIS 2 
development programe, perhaps I think more qualified ppls thinks simple 
problems in more complex
 ways, because they put so many bundles of unwanted ideas in their head and 
that comes and reflect in their new development programme areas leads and 
produce new development products and approach of simple thing in more complex 
paralytic ways. And Saptarshi, you can't be-leave, i know some of the Phd 
aspirants rangers engaged in DHIS 2 development programme, they even don't take 
proper shower every day not because they are not aware about its use and 
implications but rather because their head are full with other process and they 
don't have that much of time to go for shower, pardon but their uid's are quite 
confidential in India. Therefor I am expecting SOAP web api module development 
programme should have ppl who are only bachelors and enrolled in DHIS 2 
development programme and should be engaged in any family welfare health 
programme.
If such team is available than its fine if not than it must be introduced in 
DHIS 2 development programe so that
 they can think about the prospective in more likely neutral way not likely 
ionized way.

Brajesh Murari

[Dhis2-devs] Wierd ClassCastException on WebAPI calls

2013-10-14 Thread Saptarshi Purkayastha




On certain browsers and client's I've seen a wierd ClassCastException thrown 
from the server.
The status returned is 500.
But this happens only on certain clients in IE8 and Android ICS.
It works fine with Chrome, Firefox etc.

May be its related to accept header and the mimeType its sending for text/html. 
But this is only a wild guess.
Will be good to fix before the 2.13 release.

Re: [Dhis2-devs] Hello, can you help me with a query with web api.

2013-10-01 Thread Saptarshi Purkayastha

Hi Sushil,

I've tried that the dataValueSets allows for reading data values, based on 
startDate and endDate... but not indicators.
http://www.dhis2.org/doc/snapshot/en/user/html/ch25s11.html

So you will have to calculate indicators based on their definition on your own.
There is a small bug that I remember seeing sometime back that throws a 
NullPointerException if you pass only one orgUnit. The workaround is that you 
will have to pass a dummy orgunit (say the root orgUnit) that will not have 
data for the required dataset.

Does this work for you??

Subject: Re: [Dhis2-devs] Hello, can you help me with a query with web api.

Hi Sushil,
The API does not have extensive support for daily data yet. There are no 
relative periods for days, so you have to list them each explicitly, using the 
MMdd format:

http://www.dhis2.org/doc/snapshot/en/user/html/ch25s03.html

Unfortunately, I think this means you cannot get daily data for a whole year in 
one query, because the URL would be more than 9*365 (over 3000) characters 
long. So you would probably have to split it.


I agree that for daily data (what is the use case?), start and end date would 
be much more convenient. But you could build that logic in the javascript that 
constructs the query URL.

Sushil, you cannot use start and end dates for the /analytics resource, you 
must use the standard period types (frequencies) as described here. Note that 
you can define fixed and relative periods in your query. Docs here:

Hi,

To get data for relative period (last week, last month etc) we use,

http://serverURL/api/analytics.json?dimension=dx:Uvn6LCg7dVUdimension=pe:LAST_WEEKfilter=ou:ImspTQPwCqd






To get data by specifying period we use,

http://serverURL/api/analytics.json?dimension=dx:Uvn6LCg7dVUdimension=pe:20130924;20130930filter=ou:ImspTQPwCqd

I am not sure how to get data for indicator by specifying start date and end 
date.






You should ask on dev list for that.

I was going though a issue in api checking if you know the solution.

I tried putting StartDate and enddate and chekced the daily parameter as well. 
But was not help, can you give a example for this if you have one or suggest me

Re: [Dhis2-devs] Removing camel integration module

2013-10-01 Thread Saptarshi Purkayastha

I would like to see Etags supported with our web API, if removing camel
The point is that then we can listen to the changes using ETags and check 
modification for data when new ETags are generated for the same request.
Even shallow ETags would be a good first pass, if camel is removed.

We have decided to remove the camel integration module from the dhis2 war file 
in the next release.
As the web api has matured it is now more feasible to run the likes of apache 
camel or mule or similar software as external clients of the api.

 Hi Devs,
 I would like to know what the feeling is about upgrading the lastupdated
 proprerty of datavalues to a timestamp instead of a data. The requirement
 I have in mind is related to data auditing, and having a time stamp as
 opposed to a date is useful for this purpose. It would seem this should be
 a timestamp anyway, since it is in reference to a specific point in time
 when a data value was updated.

 Any thoughts?

 On a related note Bob,  do you know how to get the real IP of the server

I am assuming you are getting the client IP shown correctly in the access
logs in tomcat.
The server IP is showing 127.0.0.1 because that what its connector has been
bound to. Change the connector's address to the public address and it will
show you that in the logs.

Connector
port=8080
protocol=HTTP/1.1

If its dynamic address, it will be problematic though...

 Hello guys.

 I want to make some little report. What I did in this first week.

 I made functionality for logging to DHIS from my application ignoring
 CORS issue on Google Chrome.  So, application  logging to DHIS , JSESSIONID
 stored in Cookie and after that I have possibility calling DHIS API
 because  JSESSIONID automatically inserted in other request headers. And
 also I can verify if credentials are correct.

 So now I can start working on the one of the main part of application .
 It is task with calling DHIS api and obtaining data for future graphs.

 I have not updated this for a while though, but it is easily done. Some

 Hi Yuriy,

 Why do you get a cross-domain issue??
 Is it because you are developing on localhost and the server you are
 using is http://apps.dhis2.org/demo http://apps.dhis2.org/dev?
 All DHIS2 URLs support Basic Authentication... so all you have to do is
 pass the authorization headers.
 Thus, I dont think we need a separate URL for authentication. Also
 tokens for getting this done during the summer is not feasible IMO.

 To deal with cross-domain calls, I suggest you to do either one of the
 two things.
 1. Put all your CSS, HTML, JS inside a folder in expanded tomcat dhis
 and run tomcat. You'll be hosted in the same tomcat as DHIS2 and hence not
 have cross-domain issues
 2. If you wish to work with the your mobile app from localhost and make
 calls to dhis2 demo, you can start Chrome with flags:
 chrome.exe --disable-web-security -–allow-file-access-from-files (or
 similar in Linux)

 Also, since this will be mobile app, the mobile browser WebView or what
 have you for the different platforms, allow cross-domain calls. So that
 will not be a deployment problem.

 It is very inconveniently using standart way of authentication  . I
 get problems with Cross-domain and other.

 So, I suggest implements some new security for accessing for API.

 It will be look like :

 Client makes a request to .../authenticate (unprotected URL) with
 credentials; server returns a secure token which contains enough
 information for the server to validate future requests.

 Client makes subsequent requests to various (protected) URLs,
 appending the previously obtained token as a query parameter.

 Since we use Spring already, the solution will make use of Spring
 Security.

 So , I think this solution will be very useful for my future

 If you agree with me I can start investigating how to implement this

 using is http://apps.dhis2.org/demo http://apps.dhis2.org/dev?
 All DHIS2 URLs support Basic Authentication... so all you have to do is
 pass the authorization headers.
 Thus, I dont think we need a separate URL for authentication. Also tokens
 for getting this done during the summer is not feasible IMO.

 To deal with cross-domain calls, I suggest you to do either one of the
 two things.
 1. Put all your CSS, HTML, JS inside a folder in expanded tomcat dhis and
 run tomcat. You'll be hosted in the same tomcat as DHIS2 and hence not have
 cross-domain issues
 2. If you wish to work with the your mobile app from localhost and make
 calls to dhis2 demo, you can start Chrome with flags:
 chrome.exe --disable-web-security -–allow-file-access-from-files (or
 similar in Linux)

 Also, since this will be mobile app, the mobile browser WebView or what
 have you for the different platforms, allow cross-domain calls. So that
 will not be a deployment problem.

 Hello guys,

 I already started working on my task with Mobile Visualizer .

 The first point in my plan is : Implement authentication functionality.

 So, I started working on first point and get some problems.

 It is very inconveniently using standart way of authentication  . I get
 problems with Cross-domain and other.

 So, I suggest implements some new security for accessing for API.

 It will be look like :

 Client makes a request to .../authenticate (unprotected URL) with
 credentials; server returns a secure token which contains enough
 information for the server to validate future requests.

 Client makes subsequent requests to various (protected) URLs, appending
 the previously obtained token as a query parameter.

 Since we use Spring already, the solution will make use of Spring
 Security.

 So , I think this solution will be very useful for my future application
 and for future external applications which use DHIS API.

 If you agree with me I can start investigating how to implement this
 functionality.

 Yuriy Bugryn

Re: [Dhis2-devs] [Dhis2-users] hibernate_sequence is working by default in Postgres

2013-05-16 Thread Saptarshi Purkayastha

DHIS2 uses the hibernate_sequence to generate the id and even if you create
another sequence that will not be used.
This is the general way in which the Postgres Dialect operates.
If we've imported data outside of hibernate, there will be mismatch with
the sequence generator and this is the current problem you are facing.

One approach for us could be to change the dialect to be able to deal with
this problem, such that every auto-increment column has its own sequence.
That sequence can be used if data is imported into the database.
Here is some discussion around that -

 Unfortunately, Now If  i am create a new dataelemt then it is not taking

[Dhis2-devs] Migrating from MySQL to PostgreSQL

2013-05-07 Thread Saptarshi Purkayastha

Hello DHIS users and devs,

Apologies for the long email... Should have probably been multiple blogpost
to reduce its length...

I recently encountered a situation with a very large implementation of
DHIS2 having problems generating data mart.
Thus no reports were generated and only data entry was being done. I
thought I'd share some of the experiences to solve these issues, so that it
might be useful to other implementers.
Some changes will be needed in the DHIS2 source, so sending this to the dev
list also, where dev-related discussions can follow-up.

While PostgreSQL is our recommended database, many implementations have
also used MySQL.
My findings clearly highlight that DHIS2 performs much better on PostgreSQL
and there are also some bugs related to MySQL dialect.
Total org units - 26303
Total Monthly datasets - 9
Total Daily dataset - 1
Total Yearly dataset - 3

The implementation has about 34 million datavalues (non-zero)... but I
pruned it for my benchmarking. I added 1-million datavalues and ran the
data mart.
The results are from my fairly good laptop (quad-core i7; 8GB RAM; tuned
JVM; tuned MySQL 5.5 (4GB RAM); tuned PostgreSQL 9.2 (4GB RAM); 240GB SSD)
Using DHIS2 2.11. When doing MySQL benchmark turned off all services
including postgres and vice versa.
Java Opts:  -Xmx3G -Xms768m -XX:MaxPermSize=512m
Java version: 1.7.0_21 x64
Java vendor: Oracle Corporation OS name: WindowsMySQL = datamart completed
in 3hrs 46min 12sec
PostgreSQL = datamart completed in 2hrs 5min 16sec

So, it is obvious that PostgreSQL is doing datamart much faster. The
advantages might scale better if larger number of datavalues
One could argue MySQL 5.6 has many performance improvements, I didn't have
time to explore that.
The migration to PostgreSQL has some challenges. Following are steps I
followed:

 - Take the mysqldump
 - replace bit(1) to tinyint(1) in the SQL file
 - You'll see that column names are camelCase. This is an issue because
postgres will added a double quotes around to get case-sensitivity, which
MySQL by default nicely excludes.
So you'll have to make all column names to lowercase and remove the quote
characters. I did this with a simple java program. There are 150-odd column
names that need changes.
 - Used Navcat premium (trial version or SQLSquirrel also has this
feature). Data transfer is the name of the feature that will move data
from MySQL to Postgres
 - In MySQL non-standard use of boolean (which came only a few yrs back),
its converted to smallint in Postgres. I wrote a JDBC program to change
column type from smallint to boolean. A single table example is as follows
that can be made into a looping procedure as well in pure PSQL.
ALTER TABLE indicator ALTER COLUMN annualized TYPE boolean
USING CASE WHEN annualized = 0 THEN FALSE
   WHEN annualized = 1 THEN TRUE
   ELSE NULL
END;
 - remove NULL values from minimumvalue column of minmaxdatalement table
DELETE from minmaxdatalement WHERE minimumvalue=NULL
 - remove NULL values from maximumvalue column of minmaxdatalement table
DELETE from minmaxdatalement WHERE maximumvalue=NULL
 - remove NULL values from name column of relationshiptype table
DELETE from relationshiptype WHERE name=NULL
 - blobs to bytea conversion is a mess and I had to truncate. Probably a
JDBC based connector program will do better conversion, but I just
truncated it and accepted the data loss to systemsetting and usersetting :-)
*
Devs*:
We need to make all column names lowercase in hbm.xml files in code. This
will ensure portability and is generally a good practice.
We should also have a convention of using last_updated instead of
lastUpdated in column names, as is the common practice.

We are in the process of changing some of the projects to make them
possible for students who are new to DHIS2.
From the question that have been coming from the students, we realize that
some of the projects might require quite a bit of understanding of DHIS2
before they can be attempted. So, we are trying to simplify the projects.
I would request you to keep checking the projects page -

Also would be good if you hung out at the IRC.
There are other students and you might be going through the same problems
of starting DHIS2 development as others.

 Hello,

 My name is Rafaela. I am currently pursuing a MSc program in Computer
 Science at the Technical University of Denmark, after finishing my Computer
 Engineering BSc program at POLITEHNICA University in Bucharest.

 I have a big passion for self development and an equal passion for IT and
 programming. I have experience with Java, Android, C/C++ and python
 development. I am a very fast learner and I am a goal oriented type of
 person. I also find it important to work with deadlines and I have
 experience with working in international projects.

 I am looking for a challenge in doing something that matters and that can
 help society. While I was browsing through the project ideas submitted to
 Google Summer of Code I found your project and I think that your work is
 amazing!

 I especially like the idea about the mobile application for a health
 worker workplan! I instantly thought about applying for this! I think it is
 something that can make a difference. While I think the idea of monitoring
 mothers and their children from ante-natal care to post-natal care and
 further is a very good usability case, I also consider that the app can be
 made to be used in other cases as well (e.g. tracking patients who have
 suffered from strokes or suffer from diabetes for instance). As I see it,
 the app can be made in a way in which the purpose of the workplan can be
 generated based on the patient’s need. Also, I believe the app needs to be
 easily extendable in the future, because this has a high potential and it
 can have a high impact on society.

 I also took a look and played with the demo (apps.dhis2.org/demo) and I
 saw there are some steps already made in the mobile direction. I wanted to
 ask if the project would involve taking this further or would it involve
 making a new app from scratch. However I suppose that since the steps seem
 to be only for a web version, in order to provide offline functionality, a
 native application would be better.

 I would be interested in having more information about the purpose you
 have considered for this idea and also, I would be very interested what
 else can I do before applying in order to get even more familiarized with
 the project.

 Have a nice day,
 Rafaela Voiculescu*

Re: [Dhis2-devs] GSoC 2013

2013-04-18 Thread Saptarshi Purkayastha

Hi Shruti,

Thank you for your interest in contributing to the DHIS2 project.
Each of the project that you listed, require understanding the data model
and domain model of DHIS2.
The following slides might give an overarching idea -
http://www.uio.no/studier/emner/matnat/ifi/INF5750/h12/undervisningsmateriale/dhis-2.pdf

Being able to connect ODK to DHIS2 has many advantages. It is a widely used
client application and many projects in the countries where we have DHIS2
implementations use ODK. The core of ODK is the JavaRosa Xforms standard. -
http://opendatakit.org/help/form-design/
Understanding this, will be required, so that the submitted Xforms from
JavaRosa can be imported into DHIS2.

The native DHIS2 exchange format is called DXF 2.0. An XSLT transform to
convert an Xforms to DXF and vice-versa, might be one approach to do this
integration between ODK and DHIS2. You could suggest another approach.
Please look through these and feel free to come back with questions on
this.

Also would be good if you hung out at the IRC.
There are other students and you might be going through the same problems
of starting DHIS2 development as others.

Re: [Dhis2-devs] Non-gregorian calendar systems

2013-04-13 Thread Saptarshi Purkayastha

I think we should be Calendar agnostic in code and like most i18n capable
systems, not expect the timestamp in the database to be Calendar-specific
Postgres for instance uses Julian calendar internally. But still supports
many different systems, much more than standard SQL asks for.
Java similar uses long values, instead of Calendar-specific representations.

My point is, Java, Postgres (and MySQL) are well designed to work by being
calendar-agnostic.
Also,
Joda-timehttp://joda-time.sourceforge.net/apidocs/org/joda/time/chrono/package-summary.htmlprovides
nice Chronology classes for different calendars, which we can use
for localized storing, retrieving or converting

For the JavaME app in one of the releases, we did have a custom calendar
component.
Having it display BS, Ethiopian or anything else, should be fairly easy.
But yes, very few low-end Java phones are locale specific.

Hi Saptarshi,
Yes, I cannot speculate really why DHIS2 only supports the Gregorian
calendar, but this issue I think has been discussed a few times on the list
before (perhaps for other countries).

I feel the best approach would be to store all of the data with Gregorian
dates, but what is shown through the web UI would be the calendar system of
the particular instance. I am not even sure if databases like Postgres and
MySQL (much less the operating system itself) would support non Gregorian
calendar systems.

As for data exchange, I see no immediate need for this, but if data is
stored in Gregorian format ( I suppose the de facto international
standard), then perhaps data exchange would be somewhat easier, but this is
just speculation of course.

Thanks for the link to the BS date picker. Does not seem to difficult to
solve at least this problem.The bigger issue as I see it would be data
entry through mobiles. At least the J2ME app uses the system calendar, and
do not think that non-Gregorian systems are even supported on any phone?

the more localized Calendar.getInstance(). The first task would be move to

Secondly, is conversion between Gregorian dates and some other calendar

different calendars, this is important. But if we are storing a timestamp

not too keen, unless really required to use the maps that allow co-relating
dates between calendar systems.

Thirdly, there are quite a few (and fairly easy to write new JavaScript
calendars) to suite different locales. The care that we need to take is
being able to retrieve the correct calendar based on the set locale. A

Hi Devs,
I have a question regarding non-Gregorian (Western) calendar systems.
This issue has come up in a couple of different places which I know of,
namely Ethiopia (Ethiopian calendar) and Afghanistan (Solar Hijri
calendar). Currently, the system only supports a Gregorian calendar system,
but I am trying to think of ways how we can support different
ones, specifically the Bikram Sambat (BS) calendar system used in Nepal.

There appears to be no easy way to convert between a Gregorian
calendar. I dug out some code here
https://github.com/bahadurbaniya/Date-Converter-Bikram-Sambat-to-English-Date
which
will convert between Gregorian dates and BS dates (but not the other way
around). The approach is to use a look-up table, because of the fact that
it seems to be difficult (if not impossible) to calculate the
conversion algorithmically.

This leads me to my question. Would it be possible that we consider
adding a Calendar system to the application. The default would be
Gregorian, which is currently the case. The Second alternative might be
Bikram Sambat. This would require someone to prepopulate the system with
periods (BS months, quarters and years) which would be calculated through
some other means (common Lisp code
herehttp://emr.cs.uiuc.edu/~reingold/calendar.l which
may be able to do this). These would be in Gregorian periods, but instead
of the system calculating future periods, they would

Hi Saptarshi,
Yes, I cannot speculate really why DHIS2 only supports the Gregorian
calendar, but this issue I think has been discussed a few times on the list
before (perhaps for other countries).

I feel the best approach would be to store all of the data with
Gregorian dates, but what is shown through the web UI would be the calendar
system of the particular instance. I am not even sure if databases like
Postgres and MySQL (much less the operating system itself) would support
non Gregorian calendar systems.

Secondly, is conversion between Gregorian dates and some other calendar
really required. If data is exchanged between different systems with
different calendars, this is important. But if we are storing a timestamp
in database, it should be fine to store it in the locale calendar. So I am
not too keen, unless really required to use the maps that allow co-relating
dates between calendar systems.

Thirdly, there are quite a few (and fairly easy to write new JavaScript
calendars) to suite different locales. The care that we need to take is
being able to retrieve the correct calendar based on the set locale. A

 There appears to be no easy way to convert between a Gregorian calendar.
 I dug out some code here
 https://github.com/bahadurbaniya/Date-Converter-Bikram-Sambat-to-English-Date
  which
 will convert between Gregorian dates and BS dates (but not the other way
 around). The approach is to use a look-up table, because of the fact that
 it seems to be difficult (if not impossible) to calculate the
 conversion algorithmically.

 This leads me to my question. Would it be possible that we consider adding
 a Calendar system to the application. The default would be Gregorian,
 which is currently the case. The Second alternative might be Bikram
 Sambat. This would require someone to prepopulate the system with periods
 (BS months, quarters and years)   which would be calculated through some
 other means (common Lisp code 
 herehttp://emr.cs.uiuc.edu/~reingold/calendar.l which
 may be able to do this). These would be in Gregorian periods, but instead
 of the system calculating future periods, they would have to be
 pre-calculated and entered/imported into the system somehow.

 The second part of this (which I think may be more difficult) is the use
 of the JavaScript Gregorian calendar throughout the system. For data entry
 of aggregate data, it would not to be too problematic. But for the tracker
 module (and other places in the system), a Gregorian Javascript widget is
 used, and it would seem to be potentially difficult to replace this.

 Could the developers comment on feasibility and possible level of effort?

[Dhis2-devs] DHIS2 participating in Google Summer of Code 2013

2013-04-08 Thread Saptarshi Purkayastha

Dear DHIS2 developers and users,

Today Google 
announcedhttp://google-opensource.blogspot.no/2013/04/mentoring-organizations-for-google.htmlthat
HISP https://www.mn.uio.no/ifi/english/research/networks/hisp/ (for DHIS2
development) has been selected as a mentoring organization for the Google
Summer of Code (GSoC) 2013 program. We feel happy that we've got the
opportunity to attract the best students to work with us over the summer on
projects that will help build tools to improve health systems. Please
spread the word among university students to apply to our project with full
zest on existing ideas, new ideas and engage in discussions with us (over
email - developers list or at the IRC - irc.freenode.net/#dhis ). I invite
all of you to hangout at the IRC.

In the coming days, we will have a number of interested students come with
their queries and questions to the list. They'd suggest their own project
ideas as well as discuss some of our suggested project
ideashttp://dhis2.org/gsoc2013.
Hopefully we'll all welcome them with open hearts and minds, and make them
part of our community.

--- About GSoC Program ---
Now in its ninth year, Google Summer of Code is a program designed to pair
university students from around the world with mentors at open source
projects in such varied fields as academic research, language translations,
content management systems, games, and operating systems. Since 2005, over
6,000 students from 90 countries have completed the Google Summer of Code
program with the support of over 350 mentoring organizations. Students gain
exposure to real-world software development while earning a stipend for
their work and an opportunity to explore areas related to their academic
pursuits, thus “flipping bits, not burgers” during their school break. In
return, mentoring organizations have the opportunity to identify and
attract new developers to their projects as these students often continue
their work with the organizations after Google Summer of Code concludes.

Below is the timeline:
 - Monday, April 8th - Accepted organization announcement
 - April 22nd to May 3rd - Student applications period
 - May 24th: Accepted students are announced
 - Till June 16th: Community bonding period
Get to know your fellow interns and mentors.
Communicate about the project, create designs and plan
 - June 17th: Coding begins
 - July 29th: Mentors send Google a mid-term evaluation of your work
 - Sep 16th: Plan to finish coding by this date. Polish code after this
 - Sep 23rd: Pencils down. Stop coding. Mentors submit their final
evaluation
 - Oct 1st: Results of evaluations are announced
For the internship, Google grants
$4500 to the student and $500 to the mentoring organization.

Re: [Dhis2-devs] GSOC 2013 Information

2013-04-08 Thread Saptarshi Purkayastha

Dear Ovidiu Rosu,

Lars forwarded me this email and I'd like to highlight that we are still in
the process of finalizing the projects.
But we have some project ideas already on our page -
http://dhis2.org/gsoc2013
These projects are new ideas, but use existing frameworks, technologies and
APIs

A good way to get started would be to compile the DHIS2 codebase and
install it.
http://dhis2.org/development - Follow the instructions from this page for
the same.
Then look through the frameworks like Struts, Hibernate and how they are
used in DHIS2. Ask questions where you get stuck and have trouble
understanding. In the process we will improve our developer documentation
and provide starting steps for DHIS2 development.

 - Will be good to signup for a launchpad.net ID
 - Signup for the  dhis2-devs mailing list...
 - Playing around with the demo - apps.dhis2.org/demo
 - Follow through the documentation -
http://dhis2.org/doc/snapshot/en/implementer/dhis2_implementation_guide_en_full.html
 - Look at the presentations -
http://dhis2.org/download/presentations/presentations.zip

These might help you give conceptual understanding about DHIS2 that will be
useful for becoming a developer on the platform.

PS: To the dev list, please help bring together other pieces of
documentation that might be useful for incoming students

 To: Lars Helge


 Hello,

 First I would like to introduce myself, my name is Ovidiu Rosu a Computer
 Science student (2nd year) from Romania looking to participate in the
 Google Summer of Code 2013 program.

 I am writing this e-mail because I've read your GSOC 2013 Project ideas /
 information (concerning the dhis2 project) and it got me really interested.
 It is the first time I've read about your project and to be honest the idea
 of using software in order to improve the health care system in poorer
 countries is really noble.

 I would like to know how to get involved in the project and try to
 contribute to it as part of my application. Are the Project ideas already
 in development or will they be implemented from scratch ?

 Where do you recommend me to start in order to get involved in your
 project ?(since this is the first time I'm getting involved in a project of
 this magnitude). Can I somehow contribute to it before the GSOC 2013 coding
 part starts?

 I will leave my contact details here:
 contact details hidden

 Thank you for your time.

 Best regards.

Re: [Dhis2-devs] Metadata's use of List

2013-04-06 Thread Saptarshi Purkayastha

If you are sorting it, the order of insertion and keeping it in order isn't
useful I guess.
Also, one could also use a ordered Set like LinkedHashSet or TreeSet
(obviously slightly slower in operation).

Would you be open to making that change, but I think in terms of expected
behavior we'd have metadata to be Collection of unique objects.

 I'm sure some of them can be made sets. But I think the main reason was
 that we wanted a stable order. For most of the types, this doesn't matter,
 but for organisation units, we are exporting according to level. Not sure
 how useful this is, since I'm currently also doing the sort before starting
 a OU import.

 This is also used for generating the API web-pages, so that all types are
 sorted on names. Which makes paging etc more stable.

 I guess you could also use a SortedSet for this.

[Dhis2-devs] Metadata's use of List

2013-04-04 Thread Saptarshi Purkayastha

Hi Morten and others,

Today when Bob and me were looking through the Metadata class, we saw List
was used.
We were hoping that the metadata objects would be unique and we'd like them
to be unique in the import-export.
We were planning to iteratively get some metadata (data elements,
categories etc.) and put them together to output as DXF.

Is there a reason not to use a Set here instead?

  Hi all,
 
  DHIS version 2.11 is out and we have some great features for you:
 
 
  - Web-based pivot table: Allows you to create pivot tables with data
  aggregated along all data dimensions, including data element/organisation
  unit group sets. Data dimensions can be arranged freely on columns, rows
 and
  as filters. You can include totals and subtotals on all axis and control
 the
  table density and font size under options. Your pivots can be saved as
  favorites and downloaded to your local computer. This design goal is to
  allow users to create their own reports with the data they need without
 any
  involvement of super-users.
 
  A pivot table with immunization indicators for last 4 quarters by
 facility
  ownership, type and location can be made like this (log in with
  admin/district):
 
  http://apps.dhis2.org/demo/dhis-web-pivot/app/index.html?id=XWXTmFUffng
 
  A pivot table with number of diagnosis by facility ownership and type
 with
  totals and subtotals looks like this (notice that diagnosis are data
 element
  groups):
 
  http://apps.dhis2.org/demo/dhis-web-pivot/app/index.html?id=vlnZeGhgw1T
 
  A pivot table for vaccines, broken down on categories, age group and
 point
  of service, last 12 months:
 
  http://apps.dhis2.org/demo/dhis-web-pivot/app/index.html?id=z31v4RMNqnu
 
  A pivot table with reporting rates, major forms for public facilities by
  location and type, last 12 months:
 
  http://apps.dhis2.org/demo/dhis-web-pivot/app/index.html?id=VHewKMjyLnR
 
  We encourage you to play around - select dimension items for the left
 menu
  and arrange dimensions from Layout in the top menu. Documentation can
 be
  found here:
 
  http://dhis2.org/doc/snapshot/en/user/html/ch15.html
 
 
 
  - Data analytics Web-API resource: A flexible API for retrieving
 aggregated,
  analytical data for all data dimensions using a simple query syntax. The
  pivot table module is built on top of this API. It allows developers of
  third-party apps and web portals to connect to DHIS 2 and query for any
 type
  of aggregated data, where any number of dimensions and filters can be
  specified. Data can be retrieved in json, jsonp, xml, csv, html and xls
  (Excel) format and responses can be constrained with criteria like
 greater
  than, equals and so on.
 
  A query for retrieving data for certain data elements, periods and
  organisation units might look like this:
 
 
 http://apps.dhis2.org/demo/api/analytics?dimension=dx:fbfJHSPpUQD;cYeuwXTCPkUdimension=pe:2012Q1;2012Q2dimension=ou:O6uvpzGd5pu;lc3eMKXaEfw
 
  Documentation can be found here:
 
  http://dhis2.org/doc/snapshot/en/user/html/ch25s18.html
 
 
 
  - Sharing: Several objects including chart, pivot table, map, indicator
 and
  data set can now be shared and have fine-grained access control. An
 object
  can be made private to yourself, shared with any number of user groups
 or be
  made available for all. You can grant edit or view-only rights to other
  people. You can create user groups directly from the dashboard. Who
 should
  be allowed to create public objects can be controlled through user roles.
 
  This functionality is useful for example in a scenario where entities
 like
  health programs and implementing partners need to create indicators and
  reports which should be available only for members of their
 organisation. In
  this case, an organisation can create a user group for their staff, then
  develop charts and maps which could be made available for that
 organisation
  only. General reports made by the ministry could still be shared with all
  and made publicly available.
 
  Another use-case is that of an international NGO with operations in
 multiple
  countries. Here, user groups could be set up for each country and
  indicators, resources, charts and reports which are country-specific
 could
  be made available for staff working in that country only, without
 appearing
  in lists for staff working in other countries. Indicators and reports
 which
  are applicable for all counties could be made accessible for all. The
  sharing solution also opens up for great possibilities when combined with
  the self-registration of user account feature.

[Dhis2-devs] WebDriver-based functional testing free for OSS projects

2013-03-06 Thread Saptarshi Purkayastha

We've had some functional testing done that was using manual scripts that a
tester needed to follow.
That proved useful for getting DHIS2 certified, but it is pretty hard to
manage regressions and that too across different browsers.
Being able to automate using WebDriver (Selenium2) seems like a useful step
forward.

SauceLabs https://saucelabs.com/pricing is providing their cloud-hosted,
testing platform available to open-source projects for free of cost.
They have a wide variety of browsers and platforms supported and helps us
avoid regressions and allows upto-date functional testing.

We should hope to migrate those manual scripts to automated using this.
I think it will be a very useful exercise in the long term for functional
testing of DHIS2.

 You are right of course.  The fix fixed only one of the 3 issues and

 A proper fix requires the addition of fields in the email setup
 configuration which currently has just hostname, username and
 password.

 In addition what is required are:
 port number, reply to address (these could be populated with defaults)
 and probably a checkbox for no smtp authentication required.

 I know Lars was concerned about having too much to configure but I
 think the above would be fine provided there were sensible defaults.
 Lars, what do you think.

 Talking of which, I don't know how most implementations are
 configuring mail, but for an internet hosted server (which is
 increasingly our target) I *think* the most sensible
 zero-configuration default is to just point to localhost:25 with no
 authentication.  I think most internet servers will have a local exim
 or postfix installed for sending out system alerts and the like.  If
 not they probably should :-)

 I see the error when I type 'sh startup.sh'.

 But when I explicitly type 'bash startup.sh' all is fine.  Or even

 Can you confirm how you are starting this script?  Maybe you have a

 Also I would not suggest that dhis-live is the best option for running
 on ubuntu server if this is meant to be for production use.  It uses a
 pre-canned set of JAVA_OPTS which you would more likely want to tune

Re: [Dhis2-devs] DHIS-Live not working with Linux

2013-02-01 Thread Saptarshi Purkayastha

oops, my bad.
This is a bash script with function calls. You'll need to work with it.

You'll need to verify that the first line is indeed
*#!/bin/bash*
and the file has executable permissions

 Hi Neeraj

 This strange error seems to indicate you don't have a bash shell which
 is odd, or if you do its not being used.

 I see the error when I type 'sh startup.sh'.

 But when I explicitly type 'bash startup.sh' all is fine.  Or even
 just './startup.sh'

 Can you confirm how you are starting this script?  Maybe you have a
 shortcut which explicitly calls 'sh'.

 Also I would not suggest that dhis-live is the best option for running
 on ubuntu server if this is meant to be for production use.  It uses a
 pre-canned set of JAVA_OPTS which you would more likely want to tune
 to your environment.

Re: [Dhis2-devs] defining datavalueset reports for dhis2 web api

2012-07-16 Thread Saptarshi Purkayastha

Hi Bob,

This is very interesting.
Much closer to xforms where the form is sent without the dataValues and can
be filled with values and sent back.

Some comments:
1.) I wonder though why you are sending all the dataElements in the xml??
Is that required or we should be able to generate only those required on a
dataSet or section of a form?
2.) There should be a dataType field for the elements or are u suggesting
chatty conversation to get the types??

Other than that I wonder if the client has to deal with the transform. Or
was this just an example to generate it and will be done on the server-side.
I would suggest that the client should be able to set Accept headers and
get the template in formats that you mentioned in your email...

 Setting up a client to produce datavalueset reports using the web api

 gives you the list of dataelements to report - but finding out which
 categoryoptioncombos are required for each dataelement involves quite

 Creating an sdmx style data structure definition is difficult because
 of the raggedness of our datasets (they are not neat datacubes with
 uniform dimensionality).  So another way to approach this is to
 acquire report templates for each datavalueset - ie. retrieve the
 template from dhis and the client is then only required to configure
 itself to provide the values for each row in the template.

 The web api doesn't provide these directly, but they are easy enough
 to generate off the metadata.  At a minimum you require the datasets,
 the dataelements and the categoryoptioncombos.  If the client is a
 facility based system (like openmrs) then its really not necessary to
 get the list of 1000's of orgunits.

 Using the attached xsl and the url below is my first stab at this:

 curl -v -X GET -u admin:district
 
 http://apps.dhis2.org/demo/api/metaData.xml?assumeTrue=falsecategoryOptionCombos=truedataElements=truedataSets=true
 
 | xsltproc dxf2template.xslt - |xmllint --format -

 The resulting output (also attached) is I think the minimum
 information required to fully configure a datavalueset producer based
 on a template, using dxf2, sdmx, csv, xforms  or what have you.  I am
 assuming that a facility already 'knows' its facility identifier or
 code.

If you just want the specification for a single datavalueset template
then you really do just need the list of dataelements for that
datavalueset. Notice that you do already have that list of required
dataelements in the dataset xml - unfortunately this list format (it
is generic for all identifiable objects) doesn't contain the
categorycombo so a bit of duplication is required.

Yes, I was thinking if this duplication can be avoided. So only the
required disAggregations are received...

There should. I was assuming numeric but I guess that is not fair.

Although the type might be dataType like you did in the next xslt, it'd
still not be able to do the xforms/javarosa-style xforms because its
datatype and not viewtype. Like I could represent a multi-select through
checkbox or list etc. So, that case of having view-representation is still
missing.

I agree that the client's life could be made easier if such a
transform was done on the server side. I just put this out as a
feeler to see if people who are building dxf2 clients might find it
useful. Of course its not a big problem to do on the client side and
has the advantage of not needing to build consensus around what a
standard representation should be. But such a representation
available from the server could make building clients even easier.

xslt is fairly memory intensive because its in-memory. The newest XSLT 3.0
standard brings streaming, but that's not what you are using. This means
that clients need a lot of memory on large transforms and I'm thinking of
mobile when I was referring to be able to get this transform done on the
server-side.

Where would you map it? If you want to get all the reports like I
have done then something like application/reportTemplate+xml on
metadata url might do, The idea being that a client could read in the
list which templates it wanted to configure/save.

Slightly more chatty but maybe also sensible (but I think maybe more
complicated to implement), would be to use
application/reportTemplate+xml on the dataset url (with the
restricted list of dataelements).

a small nitpick that mime-types are generally not camelCase.
Yes, but we could have the client configure/save the XSLT on the server and
on next calls get that response only. Sadly, javarosa-xforms uses text/xml
and nothing more specific :-( . Some mobile client could nicely send an
XSLT for JSON and get that representation from the server for
reportTempate??

[Dhis2-devs] Web API Usage

2012-03-12 Thread Saptarshi Purkayastha

Dear devs,

Is there documentation about the web-api. Like what resources support
GET/POST? I see a list of all the resources and 4 representations, but is
there more detailed documentation??

I also recently saw commits from Lars that implementing caching for WebAPI.
Is there any reason not to use ETags for the purpose?? That will enable to
check if new content is exposed by the web service or not and seems like
the standard way for update checks.

Is there a way to create organization units through the Web API?? If not
the web api, are there any considerations to adding org units on-the-fly,
attaching datasets and collecting data. I vaguely remember having to do
something with resource tables. Is that still necessary??

Too many questions probably in one email... but all somehow related to one
another.

 Hi,

 as you know Oracle has withdrawn the Operating System Distributor
 License for Java which means that Oracle JDK has been removed from
 Linux package repositories. Another issue is that Oracle will no
 longer post public updates to JDK 6 after November 2012. So which JDK
 to choose for DHIS installations has become a question.

 In that regard I have done some bench-marking running a full data mart
 export using various JDK versions on Ubuntu 64bit. Each test was done
 3 times and the result is the average time.

 Sun JDK 6   2h 36m
 OpenJDK 6  3h 24m
 Oracle JDK 7   3h 25m
 OpenJDK 7  3h 34m

 A bit surprisingly Sun JDK 6 is far ahead. Will continue to
 investigate the reasons for this and monitor JDK 7 performance in
 future updates.

Thank you so much for the info Lars.
Sounds like we should be getting POST/PUT on many resources... I'd like to
vote on the org unit creation to priority :-)

Didn't realize what you were solving with the caching... but for the
client-side trying to check if new data is available, ETags are generally
useful.
Like you explain, you are solving a different problem, so it might not be
relevant.

 Server-side validation / etag based caching is not useful in this
 scenario since the main purpose (besides saving network usage) is to
 reduce the load on the server - if you are to produce reliable
 hashes/etags then you will have to generate those reports/charts first
 anyway. The idea now is to use the knowledge of when the data in the
 reports are refreshed. And then we might as well use expiration
 caching (cache-control/expiry headers) and let the client cache the
 representations completely and thus avoid the validation round-trip.
 Will write some more about this later.

2012/2/18 Lars Helge Øverland larshe...@gmail.com

 Hi all,


 DHIS version 2.7 is released. The improvements this time are: (demo
 login is admin/district)


 1) Translation of database content: Most database content, including
 data elements, indicators, validation rules, groups and group sets can
 now be translated to any language. Each user can independently decide
 what language to use in the system. To translate an object click on
 the blue translation icon next to the object in the various lists.
 Later in the settings module under general user settings you can set
 your preferred language.

 This functionality is useful for countries with more than one
 widespread language or when English is needed as a second language.
 This functionality has already been field tested in Tanzania with
 Swahili and English.


 http://apps.dhis2.org/demo/dhis-web-maintenance-datadictionary/dataElement.action


 2) Chart options in data visualizer module: Support for several
 options for chart including i) Domain and range axis labels for
 displaying the units of measure of the chart ii) Target line for
 displaying the desired target value iii) Trend line for displaying the
 trend of the chart data iv) Hide legend and title to make more space
 for the chart itself v) Dynamic inclusion of the organisation unit of
 the currently logged in user on order to make charts more reusable in
 the dashboard. The user interface for the chart options can be found
 in the bottom left corner.


 http://apps.dhis2.org/demo/dhis-web-visualizer/app/index.html?uid=nwqNUFG9Vky


 3) Option sets: Support for pre-defined sets of options for name-based
 data. You can define any kind of options, for instance an option set
 called Delivery type where Normal, Breach, Caesarian and
 Assisted would be the options. This option set can later be
 associated with any number of data elements. When doing data entry in
 name-based records module those elements will then appear in the form
 as drop-down lists with auto-completion support.

 The user interface for defining option sets are found in data
 administration module. Option sets can be associated with data
 elements in the add / update data element interface. Int the demo
 below select any facility and then the Delivery returns program:

 http://apps.dhis2.org/demo/dhis-web-caseentry/anonymousRegistration.action


 4) Data locking: New and improved solution for locking of data entry
 forms. With the new solution you define a number of expiry days for
 each data set which is relative to the end date of the data entry
 period. So when the number of expiry days has passed after the end
 date of a period, that period will be locked for further data entry.
 You can cater for special situations where data entry should be
 allowed despite the automatic locking through the lock exception user
 interface in data administration module.


 http://apps.dhis2.org/demo/dhis-web-maintenance-dataadmin/lockException.action


 5) Improved messaging: i) Paging - all messages can now be browsed
 page by page ii) Follow up - messages can be marked for later
 follow-up by clicking on the familiar star next to it iii) Faster
 navigation - buttons for marking a message as unread, remove it and go
 back are  included also at the bottom of the read message screen.

 http://apps.dhis2.org/demo/dhis-web-dashboard-integration/message.action


 6) Full data mart export: A new user interface in reports module for
 easily doing full data mart exports. You can select the period types
 and start- and end-date for which periods to include in the export.
 Full export implies that all organisation units, data elements and
 indicators are included in the export process. This means that you
 don't have to worry about getting invalid data marts as a result of
 e.g. not including all organisation unit levels. This interface
 provides you with continuous feedback so that you can easily track
 progress of the process.

 http://apps.dhis2.org/demo/dhis-web-reporting/displayDataMartForm.action

[Dhis2-devs] Lighweight DHIS for organization unit management and data entry

Hi,

Has anyone built a lightweight version of DHIS for offline data entry??
Excluding all the analytics and datamart services.
Basically want to only allow creating organization units and do data entry
for these organization units on low-end netbooks. It is probably easy to
just remove the not-required web modules from the web-portal pom.xml , but
I want to remove those services that are not required from maintainence
module.

Is there documentation somewhere for dependencies or someone already has a
lightweight version of DHIS for dataentry only??

 I built a data entry only version just by modification of the pom for use
 on Amazon micro instances, but sounds like you need additional stuff?

 Hi,

 Has anyone built a lightweight version of DHIS for offline data entry??
 Excluding all the analytics and datamart services.
 Basically want to only allow creating organization units and do data
 entry for these organization units on low-end netbooks. It is probably easy
 to just remove the not-required web modules from the web-portal pom.xml ,
 but I want to remove those services that are not required from maintainence
 module.

 Is there documentation somewhere for dependencies or someone already has
 a lightweight version of DHIS for dataentry only??

Re: [Dhis2-devs] Lighweight DHIS for organization unit management and data entry

Great... this is what I'm looking for.
Will the Android phones be using HTML5 offline support in the browsers??
Or are we talking about a mobile application/browser-view that uses the
web-api (REST services)??

I'm thinking organization unit management, so that those can be added as
well.

 This is in the short term plans. Morten and a master student will be
 working on on a light-weight browsing client with offline support (for
 example for use on Android phones).
