Wondering if anyone here has though a bit, or more thoroughly, how MapServer
could be extended to support complex features (for WFS) such as the ones of
Inspire application schemas. The lack of support for them becomes a serious
problem for existing MapServer users that have to comply with Inspire.
Looking at the GeoServer documentation about app-schema (
http://docs.geoserver.org/stable/en/user/data/app-schema/ ) or Deegree one (
feature-store §6.5.2 and following) shows the level of difficulty, just at the
configuration level. I guess that the implementation complexity would be way
My intuition is that it woud likely require parsing and understanding GML
application schema. XPath analysis. And a code base with a much more object
oriented approach to model concepts of DataStores, Types, Features,
Properties, multiple geometries per features, etc... Our current modeling of
shape attributes as a "char **values" is probably too simplistic...
I'm not sure the current codebase (and functionnality) could survive such an
