One thing that we missed in yesterdays meeting Andrea's idea of porting the
CSS module to Java for inclusion in GeoTools.
I personally like the idea as it would put the work under more response
maintenance (as befitting what is now used as a GeoServer extension). The
only thing I was worried about was isolating David Winslow, but it sounds
like he has had technical input into how to port the module.
I assume the initial port would be as a GeoTools module, and then after a
QA pass it would take over CSS translation duty for GeoServer.
Questions:
- Andrea was there anything you wanted out of a discussion before
proceeding with this work?
- My understanding is that it is unfunded, volunteer, maintenance work ...
is anyone else in position to asset on this one, or supply funding?
- On a related note is porting the CSS module a good subject for FOSS4G
code sprint?
And a technical question, is there any advantage to "going native" and just
using the CSS data structures "as is" and constructing the appropriate data
structure for the Renderer? The SLD DataStructures are currently translated
into Style2D objects in StreamingRenderer processSymbolizers. A similar
approach could be used to "directly" translate the CSS data structure.
Advantage: May be faster to implement and easier to maintain. Disadvantage:
avoiding the OGC standard - SLD support may bit rot.
