   - Please describe your application.

    - What is its name? *Iris*
         - What is the home page URL? *http://scitools.org.uk/*
         - Which OSI approved Open Source Licence is used? *LGPL* *v3*
         - What does the application do and how does it add value to the
         GeoSpatial stack of software?
         *The Iris python package allows* *users to work with large
         multi-dimensional datasets such as those found in the fields
of weather and
         climate science. Iris builds on the semantics and data model from the
         Climate and Forecasting conventions for NetCDF (CF-NetCDF)
which exist to
         define the metadata within NetCDF files in order to provide a
         description of each of the data variables including their spatial and
         temporal properties. CF-NetCDF is being adopted by the OGC as
a WCS payload

         Iris enables users of data from different sources to build
         applications with powerful extraction, regridding, and
display capabilities
         and export their data to CF compliant NetCDF. The ability to
provide data
         sets of three, four, and higher-dimensions represents a significant
         expansion of the capabilities of web coverage services* *which
         require tooling to generate the data sets.  NetCDF and t**he CF
         conventions provide extensive capabilities for multidimensional data
         * *,* *Iris can provide an interface to NetCDF data sets. ***

         - 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.
         *This Iris data model follows the CF-NetCDF 1.6 conventions **
         **Current use cases include using Iris to convert data into a
         format suitable for use with GeoServer to serve slices of
         datasets via WMS 1.1.1 and 1.3.0
         Developers are currently looking at integrating Iris with
         Zoo-project to allow users to interact with the library via WPS calls.
          - What language is it written in? *Python*
         - Which version of the application should be included in the next
         OSGeo-Live release?
          *- Iris 1.4.0 (https://github.com/SciTools/iris/tags)*

          - 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?
      *Iris was developed by the UK Met Office (metoffice.gov.uk) to
      provide a more robust, intuitive and standards complaint environment for
      use across the organisation's research and production systems.  The
      software was released as open source to ensure easy collaboration with
      partners and external developers are now also contributing to code base.
      - Ohloh <https://www.ohloh.net/> provides metrics to help assess the
      health of a project. Eg:
      http://adhoc.osgeo.osuosl.org/livedvd/docs/en/metrics.html Could you
      please ensure that your project is registered with Ohloh, and Ohloh has
      been updated to reference the correct code repository(s) for
your project.
      What is the Ohloh URL for your project?
      *  http://www.ohloh.net/p/scitools-iris*
      - What is the size of the user community? You can often answer this
      by mentioning downloads, or describing a healthy, busy email list?
      *  * *Within the Met Office we have over 250 unique users.
      Externally we are in contact with collaborators who also use the
      we would like to use OSGeo Live to increase the user base*

    -  What is the size of your developer community?
      *  The project currently has 5 full time core developers and an
      additional 3-6 developers.*

      - Do you have a bug free, stable release?
      *   Yes, The Met Office has currently deployed the stable
      1.4.0 release.*

      - Please discuss the level of testing that your project has gone
      *   The 1.4.0 release has over 1,200 unit tests.  Each pull request
      must pass peer-review and Travis CI testing before being merged into the
         e.g. **https://travis-ci.org/SciTools/iris/builds/7844677*<https://travis-ci.org/SciTools/iris/builds/7844677>
      - How long has the project has had mature code.
      *  Iris has been considered mature since the 1.0 release in October
       - 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.)
   *  **  **No, this is a software library
       For examples, see:
   - We give preference to OSGeo Incubated Projects, or Projects which are
   presented at FOSS4G <http://foss4g.org> conferences. If your project is
   involved in OSGeo Incubation, or has been selected to be presented at
   FOSS4G, then please mention it.
   *  FOSS4G 2013 Workshop: http://2013.foss4g.org/provisional/workshops#W15
   *  FOSS4G 2013 Presentation: Cartopy and Iris: Open Source Python Tools
   for Analysis and Visualisation*
   - 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.
   *   Ian Edwards - ian.edwards [ a t ] metoffice.gov.uk*
   - 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.
*   We intend to provide a PPA within the timeframe of OSGeo Live 7
**   Currently users install from recipes:
**   * *Automated Ubuntu install: **

   - OSGeo-Live is memory and disk constrained. Can the application run in
   512 Meg of RAM?
   *  Yes*

   - How much disk space will be required to install the application and a
   suitable example application?
   *  * *The Iris python code is only 3.3 Mb.  The size of the install will
   depend on which of the dependencies are already available on OSGeo Live,
   but the final install will still be small, see: **

   -  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.
   *  * *Additional sample* *data, if required, can be downloaded by the
   user from the web https://github.com/SciTools/iris-sample-data*


   - Each OSGeo-Live application requires a Project Overview available
   under a CC By <http://creativecommons.org/licenses/by/3.0/> and a
   Quickstart available under a CC
By-SA<http://creativecommons.org/licenses/by-sa/3.0/>license. (You may
release under a second license as well). Will you produce
   *  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?
   *  Windows support is still in development we currently have a small Mac
   user group - we certainly would like to be able to provide both in the
   future, but probably not on this release.*
