Hereby we would like to ask if hale studio is appropriate to be included
on the next OSGeoLive release.
Below you can find the answers to the application questions as described
on the wiki page.

Kind regards,

Please describe your application:

    What is its name? hale studio
    What is the home page URL?
    Which OSI-approved Open Source License is used? GNU Lesser General
Public Licence (LGPL) v3.0
    What does the application do and how does it add value to the
Geospatial stack of software? hale studio enables you to transform and
harmonise spatial data, with a focus on highly complex data sets. Set up
reporting, analysis and data publishing workflows easily by defining
schema mappings. Furthermore, hale studio documents the data
transformation process and its impact on data quality.
    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.
        Read and write GML (2.1.2 to 3.3)
        WFS client (1.1, 2.0, 2.0.2), including support for WFS Transactions
        WMS client (1.1.0, 1.1.1, 1.3.0)
        Simple Features SQL
        JSON (RFC 7159, ECMA-404)
        GeoJSON (IETF RFC 7946)
    What language is it written in? Java, Groovy
    Which version of the application should be included in the next
OSGeo-Live release? 3.3.0

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

    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
        State of Hamburg (Germany)
        State of Bavaria (Germany)
        State of Rhineland-Palatinate (Germany)
        Institute of Forest Management of Baden-Württemberg (Germany)
        Armed Forces (Germany)
        SMWA Sachsen (Germany)
        GDI Südhessen (96 districts and municipalities in Germany)
        Prisma Solutions (Austria)
        IGP (Portugal)
        IRCELINE (Belgium)
        HL Consulting (Belgium)
        Statkart (Norway)
        European Environmental Agency (Denmark)

Most of these organisations sponsor continued development of the
software through support contracts.

    Open HUB provides metrics to help assess the health of a project.
E.g.: http://adhoc.osgeo.osuosl.org/livedvd/docs/en/metrics.html 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?
    What is the size of the user community? You can often answer this by
mentioning downloads, or describing a healthy, busy email list?
        Downloads per year: 4.000 to 5.000
        Posts on the forum per year: 80 to 100
    What is the size of your developer community?
        At wetransform: 3 FTE
        Outside wetransform: 2-3 major contributions per year, e.g.
SQLite reader, Geoserver app-schema integration
    Do you have a bug free, stable release?
        There are stable releases for production usage available since
release 2.0.1 (2010). A release history is available through GitHub:
        The latest release is 3.2.0, with version 3.3.0 being released
this week (19.05.2017)
    Please discuss the level of testing that your project has gone through.
        hale studio's alignment creation and transformation capabilities
have been thoroughly tested in a multitude of data transformation
projects both by its developers as well as its open source user community.
        Furthermore, continuous integration tests are performed by our
build infrastructure at https://builds.wetransform.to on every commit to
the master branch. The integration test suite is continuously extended
with every new feature or problem report. We publish detailed test
reports using Allure.
        Every release candidate of hale studio undergoes additional
manual/explorative testing.
    How long has the project has had mature code?
        Version 1.0 of hale studio was released in December 2009. Since
the release of version 2.0.1 in 2010, the code base can be regarded mature.
    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.)
        hale studio has a graphical user interface to create
transformation projects and perform data transformations.
    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?
        Simon Templer (st at wetransform.to)
        Florian Esser (fe at wetransform.to) as backup
    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

Can you please discuss how your application will be installed? A custom
installation script will be used to extract the application archive at
the appropriate location and create an application launcher.

    OSGeo-Live is memory and disk constrained. Can the application run
in 512 Meg of RAM?
        Yes, though we recommend 1 GB or more. Very large/complex
transformation projects will benefit from 2GB+.
    How much disk space will be required to install the application and
a suitable example application?
        ~380 MiB including example data sets and Java runtime
    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:
http://wiki.osgeo.org/wiki/Live_GIS_Add_Project#Example_Datasets If
another dataset would be more appropriate, please discuss here. Is it
appropriate, to remove existing demo datasets which may already be
included in the standard release.
        In the standard release, some demo datasets are included. These
may be removed for the installation on the OSGeo Live DVD. The default
‘Natural Earth’ dataset could be used to illustrate the potential of the
application as an ETL tool with respect to INSPIRE and complex schemas.
However, this would be better illustrated by providing a more
specialized INSPIRE dataset.
    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?
        Yes. Both the Project Overview and Quickstart will be created
based on the existing project documentation, help and demos.
    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?
        Both Windows and Mac installers exist for the project.
Yours sincerely,
