Jody,
I have committed the initial implementation of a sample DataAccess to
GeoTools trunk. It lives in:
modules/unsupported/app-schema/sample-data-access
and has artifactId gt-sample-data-access.
sample-data-access does not depend on any other app-schema modules, so
if you have built the standard geotools modules, you should be able to
change into the sample-data-access and "mvn install".
sample-data-access provides a DataAccessFactory registered via SPI,
which can be loaded with DataAccessFinder. It responds to connection
parameters with "dbtype" set to "sample-data-access" (e.g.
SampleDataAccessFactory.PARAMS).
At the moment, the DataAccess returns two features a little like
GeoSciML MappedFeature, each with a description and shape. There are
still some shortcomings in the implementation, with some info methods
not yet implemented, and the geometries not a GeometryAttribute, but it
should in its current form be sufficient to explore the interaction
between a DataAccess and GeoServer.
Jody, please also try this in uDig. I expect some unimplemented info
methods will cause problems. Please let me know which and I will fix them.
Kind regards,
