**
- 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
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*<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 <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
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*<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 <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
development
** Currently users install from recipes:
https://github.com/SciTools/installation-recipes
** * *Automated Ubuntu install: **
https://github.com/SciTools/iris/blob/master/.travis.yml*<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.*
