Thanks for the responses everyone. We weren’t aware of the “gs:PagedUnique” WPS
process. For now we’re going try to using PagedUnique in combination with
DescribeFeatureType and see if it can match our requirements. I’ll get back to
you if we decide to implement something extra.
Cheers,
Alex

Subject: Re: [Geoserver-devel] Available Filters Community Module Proposal
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

Hi,
I think this may have been one of the posts that was missed because of the
sourceforge mailing problems. I should add that we already have something
similar running off a fork, though we need to make it much more generic. Any
thoughts? Happy to discuss further.
Cheers,
Alex

Subject: Available Filters Community Module Proposal
Hi all,
I would like to propose a community module to add a RESTful interface for
describing the filters available for a particular layer. This would entail two
new request types, "getFilters", and "getFilterValues". A "getFilters" request
would return a list of the available filters, with their names and types. A
"getFilterValues" request would describe the valid values of a particular
filter. This would make it easier for users to discover the filter
functionality available to them.
Regards,
Alex
