[ows.js] Jsonix and OGC-Schemas progress and status report

[Aleksei Valikov]

Hi everyone,

here's an update on Jsonix status.

In the last few days I've released Jsonix 2.1.1 and OGC Schemas 2.0.1:


   - https://github.com/highsource/jsonix/releases/tag/2.1.1
   - https://github.com/highsource/ogc-schemas/releases/tag/2.0.1


As well as supplimentary Jsonix Schema Compiler 2.3.1 and W3C Schemas 1.0.3:


   - https://github.com/highsource/jsonix-schema-compiler/releases/tag/2.3.1
   - https://github.com/highsource/w3c-schemas/releases/tag/1.0.3


With the latest release OGC Schemas we've added support for all of the
requested schemas including but not limited to:


   - WMS 1.0.0.
   - WCS 1.0.0, 1.1, 2.0.
   - KML 2.2.0.
   - SLD 1.1.0.
   - OWC 0.3.1.
   - CSW 2.0.2.
   - IC 2.0, 2.1.
   - SWE 1.0.1, 2.0.
   - SensorML 1.0.1, 2.0.
   - OM 1.0.0, 2.0.
   - SOS 1.0.0, 2.0.
   - GML 3.2.1.
   - GMLCOV 1.0.
   - SWES 2.0.
   - ISO 19139 20070417.
   - Sampling 2.0.
   - SPS 2.0.
   - WFS 2.0.
   - Filter 2.0.

There's actually many more schemas supported, see the README.md
<https://github.com/highsource/ogc-schemas/blob/master/README.md> for the
full list.
All of the requests for schemas which we've received are served now. Please
send more. :)
*Please let me know <https://github.com/highsource/ogc-schemas/issues> if
you need further schemas.* Otherwise I'll just add the few remaining
schemas from OWSLib <http://geopython.github.io/OWSLib/> and that would be
it for the moment.

I've also added an extensive test suite
<https://github.com/highsource/ogc-schemas/tree/master/scripts/tests>, as
far as I can tell it seems that Jsonix works pretty well for OGC schemas.
So far there were no big issues, everything could have been solved without
much effort. I am now confident that Jsonix will be able to handle XML<->JS
conversion for OGC schemas very well.

By the way, my talk "Jsonix: communicate to OGC Web Services in JSON"
was accepted
for FOSSGIS 2015
<http://www.fossgis.de/konferenz/2015/programm/events/814.de.html> so I
hope this will give some additional momentum.

*Many thanks to Bart van den Eijnden* for his contributions. His reports
and pull requests were a great help.

In the next releases we'll add more OGC schemas. A few which are still
missing from OWSLib <http://geopython.github.io/OWSLib/> and probably some
more from the most popular.

We'll also add optimized mappings. Jsonix Schema Compiler has now a
"dependencies-of-mapping"
<https://github.com/highsource/jsonix-schema-compiler/wiki/Including-Dependencies-of-Other-Mappings>
feature which may be quite useful. For instance, ISO 19139 mappings are
using in many of the second-generation OGC Schemas to describe metadata -
but they're huge! This new "dependencies-of-mapping" feature generating
optimized mappings which include only those things you really need.

In Jsonix we'll focus on modularization and minification of the JavaScript
code. I think there's a good chance to cut down the code size.

Last but not least - Best Wishes and Happy New Year!
I wish you and your families to live long and prosper.

Alexey
