Hi Alex,
as other said, the functionality you're proposing seems to be at
least partially covered by two existing features in GeoServer:
- WFS DescribeFeatureType (list of attributes and their type)
- WPS process reporting unique values of an attribute
Is the module going to offer something further? Like, for example:
- Configuration reporting which attribute it's best to filter (and not
to filter) on, e.g., based on knowledge of which attributes are indexed in
storage for example
- Soft configuration of which attributes are actually enumerated (the
paged unique process is nice, but computing unique over a very large
dataset can take forever)
Mind, don't take this a a "no" on the module, a community module can
overlap with core functionality, no problem there, it's just for discussion
sake
Cheers
Andrea
