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 
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
      o *Which OSI approved Open Source Licence
        is used? *
          + TheETF testing framework isan open source project licensed
            under EUPL v.1.2, please see it in the main webpage
            in the source code

      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
        provides metrics to help assess the health of a project. Eg:
        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
            and the discussions in the issue tracker demonstrate the
            healthy and busy user community (see
      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:
      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
            pass through automatic validations. Subsequently, the
            changes are manually reviewed and approved by the ETF
            Technical Committee
      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>); 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
    conferences. If your project is involved in OSGeo Incubation, or has
    been selected to be presented at FOSS4G, then please mention it. *
      o The ETF was already presented at FOSS4G conferences:

  * *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 available
    under a CC By
    and a Quickstart available under a CC By-SA
    license. (You may release under a second license as well). Will you
    produce this? *
      o Yes
  * *In past releases, we have included Windows and Mac installers for
    some applications. It is likely we won't have space for these in
    future releases. However, if there is room, would you be wishing to
    include Windows and/or Mac installers? *
      o No
