I'm thinking here of the CQL/ECQL filters that can be used in WMS GetMap and
WFS GetFeature requests
(http://docs.geoserver.org/latest/en/user/filter/syntax.html).
For instance a layer might have a property called 'region' which can be
filtered by three potential string values "pacific", "indian", and "southern".
Adding "&CQL_FILTER=region%20LIKE%20'pacific'" to your request would get only
the subset of data located in the pacific region.
Under the proposed module a user could make a "getFilters" request to find out
that 'region' is a potential property to filter on with type string, and make a
"getFilterValues" request to find out that the potential values of 'region' are
"pacific", "indian", and "southern".

I am fine with a community module, but I am not sure I understand about
filters? Do you mean function reference? Schema attributes overview? WFS
predefined queried?

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
