Hi Cameron - 

  this netCDF data topic is perhaps a special category, because of its 
use with climate and earth sciences data... 
Ian Edwards also points out that he is looking for increased visibility 
via OSGeo Live, something we may be able to 
help with... 

  I notice in the 1.40rc1 source tree, that most of the disk space is 
taken by the visual tests .png's
also there is one data file, lib/iris/tests/stock_arrays.npz  that is 17MB
When using git to clone the project, git adds a project directory that 
is bg, too

  Perhaps we could make a downloadable file, or even a debian package, 
of IRIS 1.4.0 that has 
a lighter footprint of test data?  for our disk-constrained project ?

  It is encouraging to hear Massimo give his enthusiastic support.. 

  best regards from Berkeley, California

We (as WHOI and USGS in north east US) are using IRIS intensively for 
plotting data in our python workflows coming from netcdf dataset. 

IRIS in union with PyCSW the Ipython Notebook (already installed in 
osgeolive 6.5) and other geo-related python libraries (all already 
installed into osgeolive) 
will allow us to build really powerful workflow .. definitely a big 
deal for the osgeolive project!
I'm strongly in favor of this addiction. 

i'll be happy to provide my contribution to build overview and 
quickstart as well.

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?

   * 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 usersto 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 the CF conventions 
provide extensive capabilities for multidimensional data , Iriscan 
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 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):

   *  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 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?

   *  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 

   *  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 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

   * 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 

      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 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.

   * OSGeo-Live is Ubuntu Linux based. Our installation preference is:

   * Install from UbuntuGIS or DebianGIS
   * Install .deb files from a PPA
   * 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?

   *  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 and a Quickstart available under a  CC By-SA license. 
(You may release under a second license as well). Will you produce this?

   * 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.
