Hej
Can the app-schema extension handle GML3 2D topology structures, like Planar Topology, as defined in GML3 spec chapter 13 (and ISO19107) ?
If so, how may GeoServer communicate (read/write) the topology information with a topology-aware client?
Best regards

Hi Andreas,
Ben can confirm but I think the answer is no. As far as I know the app-schema extensions do not extend any of the geometry modeling capabilities in geoserver, although this is is on the future road map.

Andreas,
Justin is correct: the app-schema extension uses the 2D geometry capabilities of GeoServer.
I have never tried using app-schema to map topology properties. If there are no existing bindings in GeoServer, complex types with topology properties should be treated like any other XSD complex type. It is likely that app-schema could be used to deliver these, but it has not been tested.
app-schema does not support WFS-T so does not support read/write access.
Kind regards,
Ben.

Hi,
I'm currently looking at doing some work with Justin in extending the
bindings to support schema-driven complex attributes as well as
source-data driven 2D geometry -objects, mainly in order to handle 3D
and 1D geometry and temporal data types. The approach should be fairly
generic though, and I'm interested in supporting topology operations
in queries (e.g. to support the INSPIRE Hydrographic and Transport
data models) - though this will be next year in current project
priorities.
Please provide some simple sample data, application schema and queries
for your requirements and I'll have a look to see how achievable it is
as part of the process.
Regards
Rob Atkinson

Hej
We have currently three business cases which requires various levels of
Planar 2D Polygon Topology.
When time and weather permits (I have vacation), I will describe these
in a document and send to you.
Can you point me to relevant docmentation about the INSPIRE Hydrographic
and Transport data models?
Is INSPIRE Hydrographic using the S57 (and/or the coming S100) standard?
S57 has an advanced, non-redundant topology data structure and object
model with many-many relationships between spatial and feature objects.
As I have worked with S57 for several years (developed ESRI-based
systems), I may give some assistance.
Best regards
Andreas
