Mostly if not only from the ZODB. There and from BTree/* When I built Python 2.5.1 I had to use the CFLAG -fwrapv Is this the same issue? If so, where can I add that flag so the zope .c files will be compiled correctly? What does that flag do? From the GCC manual: Using ‘-fwrapv’ means that signed overflow is fully defined: it wraps. When ‘-fwrapv’ is used, there is no difference between‘-fstrict-overflow’ and ‘-fno-strict-overflow’. With ‘-fwrapv’ certain types of overflow are permitted. For example, if the compiler gets an overflow when doing arithmetic on constants, the overflowed value can still be used with ‘-fwrapv’, but not otherwise. I can compile my stuff with Python 2.5.1 just fine. Which GCC is it built with? I've heard of another report where a MemoryError would occur with PYthon 2.5 on Linux x86 64bit. I don't have access to such a machine, unfortunately. It would be great if somebody with some C debugging skills could check this out. It might already be good to know whether it only occurs with zope.app.container, or also with other module that have C extensions. Probably any C code. Note, this isn't a bug of zopeproject :). It just shows that Python 2.4 is still the only blessed platform, for a good reason. You are correct and I shouldn't have used that subject line. I was ready to prove that it wasn't the Pythoon version but the GCC. So I installed Python 2.4.4 using GCC 4.1.2 and expected the exact same failures. I was wrong. It works as advertised. Hmm. Now I'm really confused. But; I haven't the skills to fix it. This is just so that others may see that even though some people are successful with Zope 3.4.x / Python 2.5.1 it may be a platform dependency issue as well.

[Zope3-Users] Best Practices - Zopeproject Deployment
Hi All, I have a Zope3 project that I started using 'zopeproject'. I now want to deploy this to an SVN server so other developers can checkout and work on the project. After reviewing the zopeproject and buildout docs as well as some examples like z3hello I still cannot decide the correct settings for SVN admin so that I ignore the correct things and yet still give the new developers all of the configuration requirements. For example I want to included my buildout.cfg so they can get all of the dependencies that are not listed in the default one from zopeproject. I also want to include my site.zcml. In my Linux installation instructions I have: Install Python-2.4.x Download and install virtual_env python24 virtual_env SANDBOX cd SANDBOX source bin/activate svn co url to svn server and application source Here is where the problem is though. Should I have the user install a zopeproject here first so that they get the correct paths setup? What should I do about having each user install the correct buildout.cfg since it has hard-coded paths to my egg repository? zopeproject was great for me getting started but now I am not certain how to deploy this application since it is an application framework for other developers. I would like to have an 'oship-project' like zopeproject/grokproject but that will have to wait I think.

Re: [Zope3-Users] Best Practices - Zopeproject Deployment
Hi Christophe, Thanks for your reply. Maybe my question is naive? For background my original zopeproject looked like this below the virtualenv dir: oship-- bin develop-eggs log parts src-- oship (where all the good stuff is located) oship.egg-info var apidoc.zcml buildout.cfg debug.ini deploy.ini setup.py zdaemon.conf zope.conf .installed.cfg Creating a new space using zopeproject --no-buildout oship yields this: oship-- log src-- oship (where all the good stuff will be located) oship.egg-info var apidoc.zcml buildout.cfg debug.ini deploy.ini setup.py zdaemon.conf zope.conf .installed.cfg So I want to commit 'oship' as the top level dir whihc will include all of the above files/dirs? On Sat, 2008-05-24 at 17:58 +0200, Christophe Combelles wrote: You should start your project with zopeproject --no-buildout, then commit all the files to the svn. Okay. This prevents the buildout-generated files from being included in the svn. Except for the buildout.cfg which is really my question. I have added some dependencies to this file that are not part of the normal Zope buildout (Pyparsing,mglob, etc) and it has my system specific path to my buildout-eggs (eggs-directory = /home/tim/buildout-eggs). Also my site.zcml files will be different from the zopeproject generated one because it needs to include directives for the app I am delivering. Then your users just have to svn co the project and launch the buildout to generate the remaining files. The developpers don't even need to know that you used zopeproject, this is just a buildout at the end. So, I am now thinking that I will have to have instructions in my installation instructions that tell developers to edit the 'eggs-directory' line; correct? Also they will need to install buildout (or zopeproject) and create a project space before doing the checkout? (I think I am very confused) Granted that these are developers and it shouldn't be a problem. I am just trying to be as black and white as possible since my audience typically is the Zope developer community and we all know that those that have no seen the light (or drank the kool-aid) have adverse reactions to Zopish things. :-) I just want to be as transparent as possible for developers and eventually for users as well.

z3c.formdemo/configure.zcml So now I added it to my
zopeproject/configure.zcml
!-- Add your own component registrations here --

So by now I am certain that there is something very fundamental about

[Zope3-Users] Python Package Construction
Hi All, I would like feedback on the proper/best 'Pythonic' approach. This is a rather subjective question. Where is the trade-off between package name lengths and faithfulness to the specifications? [Discussion follows] I am implementing a set of specifications for healthcare IT for Python programmers to be able to develop interoperable healthcare applications. I am using ZCA (aka.Zope3) extensively. My desire is to implement the specs as faithfully as possible for two reasons: 1) teachability - how easy/difficult is it to teach the framework and specifications to new developers? 2) maintainability - which approach, if either, will make it easier to maintain the framework if/when the specifications change? My first pass was to develop a skeleton of the specs using Interfaces from the ZCA approach and then the implementations following the document structure of the specs. The specs are available via SVN at: http://www.openehr.org/svn/specification/TRUNK/publishing/architecture/ It is best to probably use real examples. Following the document structure for packaging AND using the ZCA convention of having a sub-directory for interfaces caused massive circular import issues due to some classes being used in the interface definition of classes inside the same interface file being imported into the implementation file. If that sounds confusing; it is. It was confusing to write too. :-) If anyone has questions I'll try to expand. It is best to probably use specific, real examples. http://www.openehr.org/svn/specification/TRUNK/publishing/architecture/rm/data_types_im.pdf (note class names are converted from the upper case, underscore separated style to CamelCase) The package openehr.rm.datatypes.text defines the implementation class CodePhrase. The associated interface file openehr.rm.datatypes.interfaces.text needed CodePhrase as an attribute type in DvCodedText and TermMapping needs both CodePhrase and DvCodedText. This quickly got out of control. So my solution to solving the circular imports is to take each interface and implementation and put them into one file. Research tells me that this is probably the second mostly popular ZCA approach. So, ICodePhrase and CodePhrase are now in openehr/rm/datatypes/codephrase.py, DvCodeText and IDvCodedText in openehr/rm/datatypes/dvcodedtext.py, etc. But wait, now I don't have a 'text package'. So if codephrase.py and dvcodedtext.py were in openehr/rm/datatypes/text/ that would solve the problem. BUT! Throughout the specs many of the names are VERY long already. Adding another package name that is from 4 - 15 (or more) characters long adds to the length of already long import statements, i.e. (sorry for the email line wraps) from openehr.am.archetype.creferenceobject import ICReferenceObject,CReferenceObject should really be from openehr.am.archetype.constraintmodel.creferenceobject import ICReferenceObject,CReferenceObject Thoughts, opinions and jeers all gratefully accepted. :-) --Tim -- Timothy Cook, MSc Health Informatics Research Development Services LinkedIn Profile:http://www.linkedin.com/in/timothywaynecook Skype ID == timothy.cook ** *You may get my Public GPG key from popular keyservers or * *from this link http://timothywayne.cook.googlepages.com/home* ** signature.asc Description: This is a digitally signed message part ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] zope.interface.exceptions.InvalidInterface: Concrete attribute, existence
Hi All, [Zope3 on Linux, Python 2.4.4] I've been chasing a problem for a couple of days and I just can't figure out what the error is telling me. Thanks for any pointers. Google hasn't been much help as it mostly returns the source for the error or one conversation from 2004 discussing implementing Interfaces. The offending source code can be seen in this package: http://www.openehr.org/wsvn/ref_impl_python/TRUNK/oship/src/oship/openehr/am/archetype/?rev=0sc=0 At first I thought this was a circular import problem but now I am thinking that it may be a fundamental misunderstanding on my part in how to use Interfaces. I am currently inheriting an Interface from an associated Interface and then also inheriting the associated classes the same way. The problem begins when I attempt to import 'Archetype' which implements IArchetype. The full traceback is below but here is a synopsis: IArchetype has an attribute 'definition' which is a CComplexObject type CComplexObject implements ICComplexObject and inherits from CDefinedObject ICComplexObject inherits from ICDefinedObject CComplexObject inherits from CDefinedObject and implements ICComplexObject CDefinedObject inherits from CObject CObject has an attribute 'parent' which is a CAttribute type CAttribute inherits from Field and implements ICAttribute ICAttribute inherits from IField Traceback (most recent call last): File load_ar.py, line 183, in ? from atbldr.atbldr import CreateAT File /home/tim/projects/ref_impl_python/TRUNK/oship/src/oship/atbldr/atbldr.py, line 49, in ? from openehr.am.archetype.archetype import Archetype File /home/tim/projects/ref_impl_python/TRUNK/oship/src/oship/openehr/am/archetype/archetype.py, line 23, in ? from interfaces.archetype import IArchetype File /home/tim/projects/ref_impl_python/TRUNK/oship/src/oship/openehr/am/archetype/interfaces/archetype.py, line 23, in ? from openehr.am.archetype.constraintmodel.ccomplexobject import CComplexObject File /home/tim/projects/ref_impl_python/TRUNK/oship/src/oship/openehr/am/archetype/constraintmodel/ccomplexobject.py, line 23, in ? from interfaces.ccomplexobject import ICComplexObject File /home/tim/projects/ref_impl_python/TRUNK/oship/src/oship/openehr/am/archetype/constraintmodel/interfaces/ccomplexobject.py, line 23, in ? from cdefinedobject import ICDefinedObject File /home/tim/projects/ref_impl_python/TRUNK/oship/src/oship/openehr/am/archetype/constraintmodel/interfaces/cdefinedobject.py, line 23, in ? from cobject import ICObject File /home/tim/projects/ref_impl_python/TRUNK/oship/src/oship/openehr/am/archetype/constraintmodel/interfaces/cobject.py, line 25, in ? from openehr.am.archetype.constraintmodel.cattribute import CAttribute File /home/tim/projects/ref_impl_python/TRUNK/oship/src/oship/openehr/am/archetype/constraintmodel/cattribute.py, line 24, in ? from interfaces.cattribute import ICAttribute File /home/tim/projects/ref_impl_python/TRUNK/oship/src/oship/openehr/am/archetype/constraintmodel/interfaces/cattribute.py, line 28, in ? class ICAttribute(IField): File /home/tim/buildout-eggs/tmpJ-oHMS/zope.interface-3.4.1-py2.4-linux-x86_64.egg/zope/interface/interface.py, line 488, in __init__ zope.interface.exceptions.InvalidInterface: Concrete attribute, existence -- Timothy Cook, MSc Health Informatics Research Development Services LinkedIn Profile:http://www.linkedin.com/in/timothywaynecook Skype ID == timothy.cook ** *You may get my Public GPG key from popular keyservers or * *from this link http://timothywayne.cook.googlepages.com/home* ** signature.asc Description: This is a digitally signed message part ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

[Zope3-Users] zope.schema Question
I have a class attribute defined in an interface as such: description=Object( title=_(uDescription), description=_(uDescription of the activity.), required=True, ) I used Object because this attribute can be one of several different class instances. But I get an error: TypeError: __init__() takes exactly 2 non-keyword arguments (1 given) When the implementation is attempting to import the interface. But if I enter a default=None or description=Object(None, title=_(uDescription), description=_(uDescription of the activity.), required=True, ) I get: File /home/tim/buildout-eggs/zope.schema-3.4.0-py2.4.egg/zope/schema/_field.py, line 453, in __init__ raise WrongType zope.schema._bootstrapinterfaces.WrongType I do not have these issues using many of the other zope.schema types.

It's not for *arbitrary* objects (use zope.schema.Field or zope.interface.Attribute here). Thanks Philipp. Field doesn't work because it expects a unicode type. Attribute works but I would like to be able to flag it as 'required' which is not part of the Attribute class. Object would work if it would allow types that subclass from the schema given. A concrete example: IItemStructure(Interface) IItemTree(IItemStructure) IItemTable(IItemStructure) ... ItemTree(ItemStructure) implements(IItemTree) ItemTable(ItemStructure) implements(IItemTable) ... Now I want to allow description to be any descendant of ItemStructure. So I had hoped that: description=Object( schema=IItemStructure, title=_(uDescription), description=_(uDescription of the activity.), required=True, ) would provide that functionality. It still throws a WrongTypeError. I feel like the answer lies somewhere in the zope.interface.implement* functions but I lack the Zen to get the right combination.

I feel like the answer lies somewhere in the zope.interface.implement* functions but I lack the Zen to get the right combination. It's hard to tell w/o knowing what actually throws the exception. I think I was misreading the traceback. In stepping through the debugger I was able to determine that the type 'unicode' in the error is referring to description entries several layers up the inheritance tree. I had copy/pasted a lot of this from the specifications document and there are the strange backwards single and double quote characters in the text. The documents were created with Framemaker and then saved to PDF. So once I remove all those characters I can get back to the task at hand. Am I correct in thinking that the above definition of Activity.description will constrain the possible types to the classes implementing IItemStructure or a subclass of it? BTW: The traceback is below. I don't think it would have been possible to find this without stepping through the debugger and watching the stack data.

After flattening the nested construct and unicode converting the

[u'include', u'archetype_id/value', u'/disposition\\.v1draft/']
Same problem.
If so; if I remove the unicode declaration will that prevent this error?
Nope!
Now I don't know where to search for the problem.
Any ideas?

Re: [Zope3-Users] Set List constraints
I appreciate the list members time and patience. I used Zope heavily 2000-2003 but after not writing any code for almost five years this is like starting over. :-) On Fri, 2008-07-11 at 06:48 +0200, Markus Kemmerling wrote: You want to restrict the elements of a list to instances that provide a given interface IMyClass, right? That's exactly what a field's value_type attribute is for: Thanks. I missed that in the docs about collections. is meant to be used in class definitions to declare that a class itself -- not is instances -- provides a given interface. I use that and I guess that's why I thought it might do double duty. I am not sure if I get this. If you set an instance of a mutable type like a list as an attribute of some other instance described by a schema, it will be validated, but still remain mutable (finally your other object only holds a reference to your mutable). It doesn't matter if it is persistent or not, or if it was copied before. But I might misunderstand your intention here. As usual a bit of context will help if you'll bear with me. I am implementing a set of healthcare application specifications designed (over almost 2 decades) to maintain semantic context of information across applications and to be implementable in any OO language. There are implementations in Eiffel,Java and .Net. http://www.openehr.org This will reduce the number healthcare data silos since any application in any language can exchange information. The reference model describes broad concepts such as observation,instruction,action,etc along with the required data types and data structures to support them. The 'instances', referred to above, are created as constraints on the reference model in order to define a maximal dataset for ONE clinical concept, i.e. blood pressure. These definitions are parsed from a special purpose language (see attachment) designed to describe the entire semantics of that concept. Since (with my code) parsing one of these and creating the in-memory object takes about .1 - .2 secs. and since an application may use as many as 20 on a screen it is out of the question to do it on-the-fly. My solution then is to pre-store these in a repository in the ZODB as a kind of template. An application can then reuse these by making a copy. My priorities are: 1. To demonstrate implement-ability in Python. 2. Have a platform that can be used to demonstrate and teach the reference model and archetypes in use to a broad audience; physicians, health care researchers, computer science and medical students, etc. 3. Build an interested open source community where 'real' developers can fine tune my code and create wonderful interoperable healthcare applications using the reference model in their chosen language. So, yes I am recruiting developers to what I believe is a good cause project. In the interim I will keep plugging away at. :-) Thanks, Tim -- ** Join the OSHIP project.

Re: [Zope3-Users] Interface confusion (still)
The purpose of this question is related to an earlier question I had about using the best/correct schema field choice. It was pointed out that I should use 'Object' and set the schema to the interface of the class(es) that I wanted that attribute to accept. Since I did not point out that all of the classes that I wanted an attribute to accept would be descendants of that base class (and their interfaces) that is probably where I misunderstood that I would need to use classProvides.

The 'implements(IDvText)' statement is enough for all instances of 'DvText' to provide 'IDataValue'. Barring any replies to the contrary; I will remove all the superfluous classProvides calls. Since this makes sense to me and was my original understanding. Basically that interface inheritance acts just like class inheritance. Thanks, Tim -- ** Join the OSHIP project.

[Zope3-Users] Copying Objects from/in the ZODB
Hi All, Another basic question but I can't seem to find the easy way to do this. I have a group of instances stored in the ZODB. They are basically skeletons that I want to copy, edit and store as new instances elsewhere in the ZODB. In Zope2.x this was fairly obvious to me. Using the ZCA it isn't so obvious. Is there a class I should be inheriting from to do this or do I need to provide a copy method in the class itself? If the later; are there any good examples? Thanks, Tim -- ** Join the OSHIP project.

[Zope3-Users] Configuration Problems?
Hi All,
I've read all the books and readme's as well as most of the source. I
also went through as many tutorials as I could find. I just can't seem
to 'get' the configuration process for the ZCA.
I used Paul Carduner's ZContact tutorial. I had no problem with it.
I have a rather large healthcare project based on a robust set of
specifications. Most of the implementation for the specifications are
complete. We are just finishing a 10 day workshop on implementing these
specs. using the ZCA as the application server. We made some great
improvements in the code. But ..
When it comes to actually viewing our content with a browser we fail. I
thought that certainly a workshop full of bright people working all day
on this problem would be able to discover what is missing; nope.
If you have ZCA skills and are interested in getting into a field
developing interoperable healthcare applications for NGOs and
governments worldwide then we can offer to teach you the intricacies of
these specs in exchange for your help. We NEED you!
Running paster serve debug.ini:
The exact issue at this point is that we built a skin and layer as well
as a display form using the zc3.* eggs modeled after the ZContact
example. Using the introspector from the ZMI shows the contents of the
object and all looks okay. But if we try to use the skin and form
(named index.html) using a URL like this:
http://127.0.0.1:8080/++skin
++DemoAT/AR/openEHR-EHR-EVALUATION.goal.v1/@@index.html
we get a ComponentLookupError (traceback below). I just can't seem to
figure out WHERE the look up error is coming from.
I do see that if adapter is None:' raises the error and my guess is
that there isn't one registered for Archetype objects (these are not
Plone Archetypes). So, where to look?
The source is available at:
http://www.openehr.org/svn/ref_impl_python/TRUNK/oship
Since this is based on zopeproject the configure files and browser
subdirectory are at:
http://www.openehr.org/svn/ref_impl_python/TRUNK/oship/src/oship/
Thanks for taking a look and I hope I can encourage some (one at least)
of you to spend some time with us on this rapidly growing project.
Cheers,
Tim

Re: [Zope3-Users] Configuration Problems?
Marius,
Thanks for the feedback.
On Fri, 2008-08-01 at 21:13 +0300, Marius Gedminas wrote:
The traceback shows you the WHERE, but that's not interesting. The WHY
is interesting,
Very true.
and I could make a guess.
Your form schema contains a plain Field() field. Zope has no widgets
for this.
Usually this happens when you define a content object's interface
inheriting from IContained or ILocation. The fix is to omit __name__
and __parent__ from the interface.
and I'd change it to
class ATDemoDisplayForm(form.Form):
A simple display form Archetypes.
fields = field.Fields(IArchetype).omit('__name__', '__parent__')
mode = DISPLAY_MODE
Okay. This wasn't 'the solution' but it did give me a hint as to the
cause of the problem.
In the project we have many complex classes where attributes are of
another type within the project and not one of the basic zope.schema
types. Their interface looks like this:
archetypeId=Object(
schema=IArchetypeId,
title=_(uArchetype Id),
description=_(uMulti-axial identifier of this archetype.),
required=True,
So, since there are no widgets for these types of fields I assume then
they will cause the same error? I had hoped that it would just return a
__repr__.
So just to show something in the browser to be sure I have the wiring
correct I tried to figure out how to only display one attribute that
does have a widget:
adlVersion = TextLine(
title = _(uadlVersion),
description = _(uADL version if archteype was read in from an
ADL sharable archetype.),
required = False,
default = None
)
I tried changing the display form to:
class ArchetypeDisplayForm(form.Form):
A simple display form for archetypes.
#fields = field.Fields(IArchetype).omit('__name__', '__parent__')
fields=['adlVersion']
mode = DISPLAY_MODE
But this returns:
AttributeError: 'list' object has no attribute 'values'
in the browser (running paster serve debug.ini).
So I assume fields should be a mapping but looking through the text
files in z3c.form I can't determine the expected contents.
In fact I find this Zope convention of showing examples being created in
the Python interpreter to be very confusing. I'm sure that if you are
already familiar with the components it can be intuitive. But for
someone that doesn't know their way around yet (me). It is difficult to
determine how the code should look in a module when so often certain
things have been imported or created in an earlier example.
Case in point. I want to start by just displaying the contents of my
instance that has already been created and stored in the ZODB. I may
never need an add form, only edit and display forms.
BTW: Is this the proper way to say that I want an attribute that is a
Set and the contents must implement IAssertion?
invariants=Set(
title=_(uInvariants),
description=_(uFOPL invariant statements),
required=False,
value_type=Object(schema=IAssertion),
)
Thanks,
Tim

I've been staring at this too long I guess. :-)
Of course:
fields=field.Fields(IArchetype['adlVersion'])
works fine. So now I have something in my browser.
The question about all those potential custom widgets still exists
though.Is there a 'magic' Object widget that will walk the tree all
the way to the leaf of each object and use the z3c widget??? Probably
not but I am hoping.

Hi All, What are your thoughts on the best way to implement the configure.zcml files for this application framework? The framework is a nested structure up to five levels deep in places of approximately 150 classes. Would it be better/more efficient to create a configure.zcml in each package or just one at the top level? Another design decision is that this is a framework for application developers and probably 99% of them will have no previous Zope experience. So teaching them how to setup zcml for their own security declarations etc will be an issue as well.

With print 'Object schema validation errors=',errors: I get: Object schema validation errors= [] Object schema validation errors= [] Just to try to cover all bases. I uncommented the if test and the only print that changed was the one with just 'errors' (the last one above). It produces, as I said before: Object schema validation errors= [] Object schema validation errors= [, []] Chasing this down is definitely above my Python abilities.

Object field validation actually attempts to validate the schema (IObjectId in this case) of the object you're trying to store (the ObjectId object, in this case). If any of the fields cannot be validated during this nested validation, you get a WrongContainedType with the list of errors (one for each field). Apparently those errors have horrible __repr__s. That ought to be fixed. I'm not passing a list nor is the schema using a list. I realize that this may be pretty basic but I am missing something in reading the error.

Hi Dan, Thanks for taking a look. On Thu, 2008-12-18 at 20:06 +0300, Dan Korostelev wrote: Hi, Tim. I builded out your application and took a quick look at the error. It looks like you're mis-using the zope.schema.Field class and its interface. It should be only used in schema definition, while you are using Field instances as attributes for other objects. For example, you are defining the ObjectId as a field, but are using its instances as objects. That's not a valid use. Okay. I can accept that it might be a mis-use. I extracted the problematic code to separate file and changed the IField to Interface and Field to ``object`` (though you'll want to use Persistent, i guess) for ObjectId and ObjectRef and it works okay. :-) This is actually what I did at first. You may want to refer to the UML http://www.openehr.org/svn/specification/TAGS/Release-1.0.1/publishing/architecture/computable/UML/uml_start_view.html (This is the rm.support.identification package we are looking at) Since ObjectId is an abstract class so inheriting from object seems reasonable. However, most of the other id classes inherit from ObjectId and when they are used as attributes to other classes they need to have the meta data expected by zope.schema. Otherwise you get errors like keyword required not found (or something similar). This is true throughout the model. So my solution (and CERTAINLY there may be a better one) was to use the Field class (it is just a Python class - right?) as the base class for all of the base classes in the model. As I said before I may have miss-diagnosed the problem and may fix may break other things? Or, it might be that I don't fully understand your code and application architecture, so I would like to hear more about it. It looks quite over-engeneered to me. I fully understand why you might think that. IF you'll bear with me... healthcare information is very complex (certainly the complex domain I've run into in 32 years of dealing with information systems) and the knowledge domain is constantly changing. I have a short point paper here http://timothywayne.cook.googlepages.com/context-lies.pdf that gives a 30,000' view of the issues of semantic interoperability and computability of healthcare information. and a good introduction to the domain issues are here: http://www.openehr.org/shared-resources/getting_started/openehr_primer.html This model has more than 20 years of constantly improving RD on this subject. The key goal have always been to be abstract enough so that it can be implemented in any OO language on any platform in any type of healthcare setting and all stored patient information is guaranteed to be computable (decision support, etc) as well as maintain it's semantic integrity over the course of time irregardless of the changes in the science. So in essence you can go back to any point in time and not only know what the blood pressure of the patient was, but also what was known about blood pressure at that time. This model has been implemented in Eiffel, Java, C# and VB. The applications (both commercial and open source) have demonstrated these capabilities. Certainly the model isn't perfect but there is a completely open change management system in place that deals with any changes due to new ares or new science. In order for this Python implementation to remain as true as possible to the model as well as exercise the value in the ZCA; this is the path I have taken. Thanks for your help.

Hi Shane, On Tue, 2009-01-13 at 14:10 -0700, Shane Hathaway wrote: Sorry, but the patch doesn't make any sense. Your version of _validate_fields quietly skips validation entirely by default. First of all that is why I asked for others to look at it. :-) But I DID test it by inserting an incorrect schema and it did throw the correct error. I think it was the ShemaNotImplemented error. This was a few weeks ago but I can repeat it if needed. As I explained before; when one schema is checked by _validate_fields then all is well. The parameter 'errors' is None. Then errors is set to an empty list and any possible error msgs are appended. BUT when a schema has to check another schema because they are chained. 'errors' is already an empty list but even though the parameter errors is None a new list is appended to the first pass errors. This creates the msg WrongContainedType: [, []] because it IS a WrongContainedType because there is an empty list inside the original list. 'errors' is returned from _validate_fields back to the _validate method of the Object class where it is simply tested to see if it is empty. On this second pass it ISN't empty. It has another list inside so it fails the truth test and incorrectly throws an error. Look at the __repr__ method of the ValidationError class in the _bootstrapinterfaces.py module of the zope.schema package. This method was designed to generate short error messages, but in your case it appears to be truncating the error messages altogether. I would start by changing that particular __repr__() method to: def __repr__(self): return '%s(%s)' % (self.__class__.__name__, repr(self.args)) This version prefers verbosity. At a minimum, I hope this version of __repr__ will change the bizarre message zope.schema.interfaces.WrongContainedType: [, []] into something legible. It is more verbose. But I'm afraid it exhibits the same behavior as described above. Here are the results: in _validate raise WrongContainedType(errors) WrongContainedType: [RequiredMissing(()), WrongContainedType(([RequiredMissing(())],))] Note the empty parens. Now if I introduce bad code I get: in _validate raise WrongContainedType(errors) WrongContainedType: [RequiredMissing(()), SchemaNotProvided(())] SchemaNotProvided is correct. Though there isn't much else to go on but the full traceback points me to the right place. *** Shane, I think that so much of this is no longer useful.

There has been a tremendous amount of help from folks like you. However there is still not a solution. I have been asked several times for a 15 minute overview. This is tough given the complexity but allow me to ask the question at a more basic level. I believe it is similar to the way I asked it last year, but here goes. I'm not going to address Field or Object here, just explain the basics. class DataStructure(Persistence): abstract class class ItemStructure(DataStructure): abstract class class ItemList(ItemStructure): u Logical list data structure, where each item has a value and can be referred to by a name and a positional index in the list. The list may be empty. items = List( value_type=Object(schema=IElement), title=_(uitems), description=_(uPhysical representation of the list.), required=False ) class ItemTable(ItemStructure): u Logical relational database style table data structure, in which columns are named and ordered with respect to each other. Implemented using Cluster-per-row encoding. Each row Cluster must have an identical number of Elements, each of which in turn must have identical names and value types in the corresponding postions in each row. Some columns may be designated 'key' columns, containing key data for each row, in the manner of relational tables. This allows row-naming, where each row represents a body site, a blood antigen etc. All values in a column have the same data type. Used to represent any data which is logically a table of values, such as blood pressure, most protocols, many blood tests etc. Not used for time-based data, which should be represented with the temporal class HISTORY.. The table may be empty. class ItemSingle(ItemStructure): u Logical single value data structure. Used to represent any data which is logically a single value, such as a person's height or weight. * There are others and I left out the attributes and methods of these classes; with the exception of ItemList attribute 'items', where it is a zope.schema List but the value types are restricted to the schema described by IElement (also part of openEHR); but I think you get the idea. These classes are used as the base software for all openEHR applications. Of course the classes get more complex and deal directly with healthcare related issues. Now there are thousands of applications that will have data instance with attributes expressed in classes based on the above software that represent single (but complete) clinical concepts. But not all application user interfaces will use all available attributes of the concept. One may use an ItemTable and another an ItemList but they will both be valid in ANY application because the attribute represents a legal instance of ItemStructure. When that data instance is sent from application to another the receiving applications still needs to know the complete semantic context of when that data was collected.Think medico-legal, research and decision support over the lifetimes of patients and populations. So even if the user didn't see all the options in their GUI; it is still all contained in the data that was transfered. So how do I build my schemas so that Zope does the validation of nested schemas and even lets me use standard widgets? I hope this was less than 15 min.

In reality it inherits from an openEHR class called Locatable but that gets into another whole thing about writing queries one time that run on every openEHR application. I hope you don't instanciate any of this classes and use them for store something. Do you? [my next 15 minutes] No! These classes are part of a reference model where clinical experts can use tools to build and govern maximal data sets for clinical concepts. The tools only give them the options to use classes developed in the reference model. These are called archetypes and are represented in a language called the Archetype Definition Language (A CEN/ISO standard). They are version controlled and every compliant system will have them. To describe how they work in an application let's use just one attribute of blood pressure; 'position'. So position would be an ItemList that is composed of Elements that are of type Text. In the Archetype, position can be one of: Standing Sitting Lying Reclining A specific application may only want to use Standing, Sitting, Lying. So a GUI in one location (triage?) may only want to allow the option of Sitting. But say in the ER GUI they may want to also Standing and Lying or a cardiologist may want to record Reclining (as well as the +/-angle). Of course there is lots more to BP than this. So at the application level the archetype can be constrained to allow only certain options and at the GUI level the template can be used to further constrain the options for ease AND accuracy of data entry. But now everywhere that instance of that BP goes it can be validated against the archetype and the reference model. It really isn't unlike writing Python code that runs on multiple platforms. The exception here is that openEHR is also programming language independent. OSHIP (the app I'm working on) is the Python implementation of the openEHR specifications. It will be a framework for building interoperable healthcare applications basically by writing only the templates. This work is based on more than 20 years of research and development (and other language implementations).

[Zope3-Users] Reusing Widgets
If I have an interface (IDvText) and a class DvText (shown below). and
I want it to act exactly as a zope.schema Textline (with some additional

register/add to the TextLine widget? Apologies for the line wraps.

I do not like it because I want all the data describing the degustative experience in one page. This applies to page reloading too. I suggest using Viewlets attached to a Viewletmanager. I am just learning about these myself but it was easy to see how you can communicate between Viewlets. I recently did a remake of a Grok tutorial on viewlets: http://grok.zope.org/documentation/how-to/understanding-viewlets that demonstrates something that might help you out. Unfortunately they haven't published it yet but if you have a login on grok.zope.org I think I can share it with you. I'll also send you the code via email if you wish.
