Dear OSGeoLive team,
we contact you to kindly propose the inclusion of the ETF testing
framework in the OSGeoLive distribution.
Following the requirements, please find below the answer to the
required questions.
Please let us know if any additional clarification is needed.
Thank you in advance
* *Please describe your application. *
o *What is its name? *
+ ETF
o *What is the home page URL? *
+ http://etf-validator.net
<https://urldefense.com/v3/__http://etf-validator.net/__;!!DOxrgLBm!UvR1kftQcLgI0pIHnKKusY23bweSMhF9CdWZjAsWPgY49H9cK9Rs5HIqNIO4Ob1On0UqAiU$> andhttps://github.com/etf-validator
<https://github.com/etf-validator>
o *Which OSI approved Open Source Licence
<https://urldefense.com/v3/__http://opensource.org/licenses__;!!DOxrgLBm!UvR1kftQcLgI0pIHnKKusY23bweSMhF9CdWZjAsWPgY49H9cK9Rs5HIqNIO4Ob1OXB4gFIA$>
is used? *
+ TheETF testing framework isan open source project
licensed
under EUPL v.1.2, please see it in the main webpage
<https://urldefense.com/v3/__http://etf-validator.net/__;!!DOxrgLBm!UvR1kftQcLgI0pIHnKKusY23bweSMhF9CdWZjAsWPgY49H9cK9Rs5HIqNIO4Ob1On0UqAiU$>and
in the source code
<https://urldefense.com/v3/__https://github.com/etf-validator/etf-webapp/blob/master/LICENSE__;!!DOxrgLBm!UvR1kftQcLgI0pIHnKKusY23bweSMhF9CdWZjAsWPgY49H9cK9Rs5HIqNIO4Ob1OzRXGAWQ$>.
o *What does the application do and how does it add value
to the
GeoSpatial stack of software? *
+ It is an open source testing framework that allows
validating spatial data, metadata and web services in
Spatial Data Infrastructures (SDIs) according to defined
Abstract Test Suites and Executable Test Suites.
Executing
these validations may increase the level of
interoperability
of SDIs by improving the compliance of geospatial data,
metadata and services.
o *Does the application make use of OGC standards? Which
versions
of the standards? Client or server? You may wish to add
comments
about how standards are used. *
+ The ETF testing framework allows GIS data providers and
solution providers to check whether data sets, network
services and metadata meet the requirements defined on
specific Abstract and Executable Test Suites. The
concepts
in ETF are based on ISO 19105 and the OGC Specification
Model which underpin the standards used in SDIs.
+ Validation capabilities span a wide range of OGC
standards.
For example, tests to validate WMS, WMTS, WFS, WCS,
SOS and
CSW are available, which are also partially reusing
the OGC
TEAM Engine suite.
o *What language is it written in? *
+ Java, HTML, JavaScript, CSS
o *Which version of the application should be included in
the next
OSGeo-Live release? *
+ ETF 2.0
* *Stability is very important to us on OSGeo-Live. If a new user
finds a bug in one application, it will tarnish the
reputation of
all other OSGeo-Live applications as well. (We pay most
attention to
the following answers): *
o *If risk adverse organisations have deployed your
application
into production, it would imply that these organisations
have
verified the stability of your software. Has the application
been rolled out to production into risk (ideally risk
adverse)
organisations? Please mention some of these organisations? *
+ European Commission, Joint Research Centre (use of
the ETF
testing framework as the core component of the INSPIRE
Reference Validator)
+ Organisations in several EU Member States at the
national
and regional level (using the ETF testing framework to
replicate the tests of the INSPIRE Reference Validator
and/or extending these tests to include tests to check
compliance with national requirements)
o *Open HUB
<https://urldefense.com/v3/__https://www.openhub.net/__;!!DOxrgLBm!UvR1kftQcLgI0pIHnKKusY23bweSMhF9CdWZjAsWPgY49H9cK9Rs5HIqNIO4Ob1OtMqComw$>
provides metrics to help assess the health of a project. Eg:
http://adhoc.osgeo.osuosl.org/livedvd/docs/en/metrics.html
<https://urldefense.com/v3/__http://adhoc.osgeo.osuosl.org/livedvd/docs/en/metrics.html__;!!DOxrgLBm!UvR1kftQcLgI0pIHnKKusY23bweSMhF9CdWZjAsWPgY49H9cK9Rs5HIqNIO4Ob1OvPpGSUg$>
Could you please ensure that your project is registered with
Open HUB, and Open HUB has been updated to reference the
correct
code repository(s) for your project. What is the Open HUB
URL
for your project? *
+ https://www.openhub.net/p/etf-validator
o *What is the size of the user community? You can often
answer
this by mentioning downloads, or describing a healthy, busy
email list? *
+ There is a mature user community developed around the
main
implementations of the ETF testing framework. For
example,
the number of downloads of the INSPIRE Reference
Validator
(the most popular implemetation of the ETF) is
approximately
between 1 and 3 hundreds for each release (see
https://hanadigital.github.io/grev/?user=etf-validator&repo=etf-webapp
<https://hanadigital.github.io/grev/?user=etf-validator&repo=etf-webapp>)
and the discussions in the issue tracker demonstrate the
healthy and busy user community (see
https://github.com/INSPIRE-MIF/helpdesk-validator/issues/
<https://github.com/INSPIRE-MIF/helpdesk-validator/issues/>).
o *What is the size of your developer community? *
+ Currently, the developer community is mainly limited
to the
two organisations which are funding the development
of the
ETF, i.e. the European Commission and interactive
instruments (https://www.interactive-instruments.de/en
<https://www.interactive-instruments.de/en>). Sometimes,
developers from organisations deploying the ETF at their
premise contribute code with ad hoc pull requests.
Funding
to improve the developer community is currently
available
and the submission of the ETF to the OSGeoLive is one
of the
steps to increase such community.
o *Do you have a bug free, stable release? *
+ Yes, ETF 2.0 is the latest stable release:
https://github.com/etf-validator/etf-webapp/releases/tag/2.0.0
<https://github.com/etf-validator/etf-webapp/releases/tag/2.0.0>
o *Please discuss the level of testing that your project
has gone
through. *
+ The ETF has a continuous integration cycle
established in
the GitHub repository, where contributions to the source
code (which have to adhere to the contribution
guidelines
<https://github.com/etf-validator/governance/blob/master/TOR/Contribution.md>)
pass through automatic validations. Subsequently, the
changes are manually reviewed and approved by the ETF
Technical Committee
<https://github.com/etf-validator/governance/blob/master/TOR/Technical_Committee.adoc>.
o *How long has the project has had mature code. *
+ The project is active since 2007 (see
https://github.com/etf-validator/etf-webapp/releases
<https://github.com/etf-validator/etf-webapp/releases>); the
latest stable release (v.2.0) was released in 2019.
* *OSGeo-Live is targeted at applications that people can use
rather
than libraries. Does the application have a user interface
(possibly
a command line interface) that a user can interact with? (We
do make
an exception for Incubated OSGeo Libraries, and will include
Project
Overviews for these libraries, even if they don't have a user
interface.) *
o Yes, the ETF testing framework has a user interface.
* *We give preference to OSGeo Incubated Projects, or Projects
which
are presented at FOSS4G
<https://urldefense.com/v3/__http://foss4g.org__;!!DOxrgLBm!UvR1kftQcLgI0pIHnKKusY23bweSMhF9CdWZjAsWPgY49H9cK9Rs5HIqNIO4Ob1OHj1k4aA$>
conferences. If your project is involved in OSGeo Incubation,
or has
been selected to be presented at FOSS4G, then please mention
it. *

* *With around 50 applications installed on OSGeo-Live, us core
packagers do not have the time to liaise with every single
project
email list for each OSGeo-Live release. So we require a
volunteer
(or two) to take responsibility for liaising between
OSGeo-Live and
the project's communities. This volunteer will be responsible
for
ensuring the install scripts and English documentation are
updated
by someone for each OSGeo-Live release. Also test that the
installed
application and Quickstart documentation works as expected on
release candidate releases of OSGeo-Live. Who will act as the
project's liaison person. *
o Enrique Soriano (jenriquesoriano at guadaltel.com) and José
Barrero (josebarrero at guadaltel.com)
* *OSGeo-Live is Ubuntu Linux based. Our installation
preference is: *
1. Install from UbuntuGIS or DebianGIS
2. Install .deb files from a PPA
3. Write a custom install script<=== preferred option*
*
*Can you please discuss how your application will be
installed. *
o Write a custom install script
* *OSGeo-Live is memory and disk constrained. Can the
application run
in 512 Meg of RAM? *
o No. A machine with at least 4 GB Ram (8GB are
recommended, 16 GB
and more if a large set of XML files are tested)
* *How much disk space will be required to install the
application and
a suitable example application? *
o It depends on the tests executed, but 1 GB HDD can be
enough.
* *We aim to reduce disk space by having all applications make
use of
a common dataset. We encourage applications to make use of the
example datasets already installed: *
* *Each OSGeo-Live application requires a Project Overview
