I wrote a proposal for an effort to specify (= profile) a geospatial search protocol. Background: Currently, implementations of geospatial catalogue (search) services, like CSW, are rare. Some say ([http://www.digitalearth.com.au/2006/06/23/lightweight-web-resource-catalogue/][http://geotips.blogspot.com/2006/02/more-simple-web-services-catalogues.html]) that they are too complicated while the problem supposedly lies deeper: it's probably the metadata model which is also too sized. On the other hand there seems to be a trend towards search protocols (Web 2.0). So perhaps time is ripe for another effort.

Here are some requirements: simple and light weight (i.e. REST full like WxS), based on recent international standards (WFS, Z39.50 or UDDI all seem too grave), ... Any comments?

I wrote a proposal for an effort to specify (= profile) a geospatial search protocol. Background: Currently, implementations of geospatial catalogue (search) services, like CSW, are rare. Some say ([1][2]) that they are too complicated while the problem supposedly lies deeper: it's probably the metadata model which is also too sized. On the other hand there seems to be a trend towards search protocols (Web 2.0). So perhaps time is ripe for another effort. Proposal: See Simple_Catalog_Interface SFK 19:58, 13 July 2006 (CEST)
