[Geoserver-devel] App-schema: mapping GeometryArrayPropertyType

[Andrea A. <and...@ge...>]

Hi,
still looking into app schema here. Today I noticed that the schema I
have to map to uses a
GeometryArrayPropertyType. As far as I can see there is no support for it.
A GeometryArrayPropertyType is not a GML geometry (like
GeometryCollection), and it's not
a multi valued property either, it's a plain jane container of
heterogeneous geometries instead:

<mygeomarray>
  <Point>...</Point>
  <Polygon>...<Polygon>
  ...
</mygeomarray>

Now... how the heck to I map to this? I guess there are two questions
to be answered:
- what in memory representation to give the array
- how to make the encoder turn it into an array

Plan A:
- assume the geometries are all in the same SRS
- represent the thing as a GeometryCollection
- roll out a binding for GeometryPropertyType that can take a
GeometryCollection and encode it

Plan A.1:
- as above, but create a converter from GeometryCollection to
Geometry[]. Wondering if the
  encoder at this point will know what to do, or if I still have to
create a (simpler) binding

Plan B:
- represent the attribute as a Geometry[] directly
- modify app-schema to handle that case as well?
- create a binding to encode the thing.

I'm leaning towards A.1 but would like to hear what others think about
this case.

Cheers
Andrea
