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
-Brian

Hi,
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.
cheers,
Massimo.

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?

* 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
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):
* 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?
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 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
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 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.

* 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
development
Currently users install from 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 and a Quickstart available under a CC By-SA 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.
