This looks very interesting, and a nice formalization of things that where discussed on this list a while ago.
One thing wondering if would be nice to be able to specify something like: <opensearchgeo:extents>49,-9.5,62,2.3</opensearchgeo:extents> in the main definition block. Not sure of the practical use, or how it would be understood by the search initiator, but in theory it should allow an engine to state where it works. So if the initiator is capable of talking in boxes then it could know what is a rational search (assuming the engine isn't global) (btw haven't given this much thought, so the actual format of the tags, or if it could also be specified as a country code, or lat/long/radius extra. But the basic idea would to specify a geographic extent. ) FWIW, geograph.org.uk, now supports this extension: http://www.geograph.org.uk/stuff/osd.xml (well technically it doesn't actually mark up the results correctly, but something to be worked on!) Now who is going to be the first initiator capable of creating a geo search via this, (for running against mapufacture.com or geograph.org.uk, unless someone knows of more...) ? ;) On 6/15/07, Andrew Turner <[EMAIL PROTECTED]> wrote:
Greetings - as some of you may know - from WhereCamp - we rapidly put together a draft specification of OpenSearch-Geo. We did it with DeWitt Clinton - the original mastermind behind OpenSearch, and had general consensus in the group. I've posted the draft here - with some modifications: http://www.opensearch.org/Specifications/OpenSearch/Extensions/Geo/1.0/Draft_1 I would definitely like any more feedback or thoughts people could offer on the spec. The guiding principle behind the spec was to make it work with existing services where possible (hence the bbox w,s,e,n order) and also make it parallel to GeoRSS and GeoJSON. This makes it easier for all the specs to try and move forward together in the future (we can argue concepts/terminology once and have it apply to all) as well as educating other developers and users by being able to instruct once and have common concepts carry over to the different "formats". I figured Friday afternoon - you're all looking for some interesting reading and the weekend to play with it. :) Thanks Andrew -- Andrew Turner [EMAIL PROTECTED] 42.2774N x 83.7611W http://highearthorbit.com Ann Arbor, Michigan, USA _______________________________________________ Geowanking mailing list [email protected] http://lists.burri.to/mailman/listinfo/geowanking
