Chris, you read my mind. I'm supposed to be back in Atlanta on Sunday
night, so I can look into it on Monday.
Thank you very much Joe!
I also wonder... would you be eventually interested to contribute to
GeoAPI [1] too? This is not exactly SIS, but closely related since SIS
aims to be a GeoAPI implementation. Scope would be eventually larger,
since - if GeoAPI has some success - it would hopefully be implemented
by more software than just SIS. It is a "kind of work" slightly
different than SIS, in that SIS is more about extensive coding, while
GeoAPI is more about looking carefully to international standards.
GeoAPI is an Open Geospatial Consortium (OGC) working group, but
volunteers can contribute without being OGC member since the SVN
repository is hosted by SourceForge. However most GeoAPI work has to be
given OGC copyright, but the license is BSD-like.
One GeoAPI work that I'm thinking about is the "Geospatial integrity of
geoscience software (GIGS)" [2] test suite. GIGS tests were created by
the authors of the EPSG database (a very important piece of information
in a SIS). Those tests are provided as Excel documents. In GeoAPI, we
started to implement them as JUnit tests [3]. We ported the series 2000
and series 3000 tests, but more series need to be ported. Libraries like
SIS inherit automatically those test suites, so GeoAPI tests could be
used for making comparative analysis of correctness of different
geographic software (I think it could be a nice FOSS4G presentation - we
will be able to compare SIS with Proj.4).
However one inconvenient is that Apache SIS is not yet able to run those
GIGS tests. If you were working on GIGS tests and wanted to try them,
you would have to test with the Geotk library for now (a LGPL library
which is the source of the code ported and relicensed to Apache)... It
would be a temporary situation, since my goal is to finish porting the
Geotk referencing module (and hopefully more than just that module)
before the Nottingham FOSS4G meeting. However I think it is perfectly
normal if you prefer to focus on SIS, so GIGS tests are really just an
idea that I tell just in case.
