Ian,
Thanks for your application for IRIS. The project does seem to have much
going for it.
The question I'm still unclear on is whether the project is too
specialised for the vast majority of people who pick up OSGeo-Live, and
is it seriously used outside of UK Met Office.
A primary focus on OSGeo-Live is to help new users looking for
established OSGeo projects. (A side benefit of helping new users is that
we provide a marketing pipeline for the established projects).
We need to be careful that we don't include every project looking for a
community, as it confuses users, which in turn reduces the value of
OSGeo-Live for all.
Based upon your explanation below, it seems that IRIS still would need
to attract users from outside the UK Met Office before it could be
considered to have an established community?
Is this something you can talk to? Maybe IRIS would be a better
candidate to join OSGeo-Live in a future release?

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
definitive 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 format.
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 **http://www.opengeospatial.org/standards/netcdf**
**Current use cases include using Iris to convert data
into a format suitable for use with GeoServer to serve
slices of multi-dimensional 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 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?
*Iris was developed by the UK Met Office (metoffice.gov.uk
<http://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.*
o 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*
o
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 software, we would like to use OSGeo Live to increase the
user base*
o What is the size of your developer community?
* The project currently has 5 full time core developers and
an additional 3-6 developers.*
o
Do you have a bug free, stable release?
* Yes, The Met Office has currently deployed the stable
1.4.0 release.*
o
Please discuss the level of testing that your project has gone
through.
*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 project
e.g. **https://travis-ci.org/SciTools/iris/builds/7844677*
o How long has the project has had mature code.
* Iris has been considered mature since the 1.0 release in
October 2012.*
*
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:
http://scitools.org.uk/iris/docs/latest/gallery.html*
* 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
<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 development
*
* Currently users install from recipes:
https://github.com/SciTools/installation-recipes
<https://github.com/SciTools/installation-recipes>
*
***Automated Ubuntu install:
**https://github.com/SciTools/iris/blob/master/.travis.yml*
* 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:
**http://scitools.org.uk/iris/docs/latest/installing.html#build-requirements*
*
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 this?
* 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.*
