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)
BOF on Geodata Discovery and Metadata Models
This is an open BOF; participants are welcome!
Organization: See OSGeo_at_FOSS4G2006#BOFs

- Participants: curr. expected about 8
- Duration: One hour
- Time: Thursday, 14 Sept., 12:30-13:30 (not Tuesday, 12 Sept., 17:30-18:30)
- Room: Amphimax (MAX 351).
- Infrastructure: Beamer, (Sandwich ok)
Agenda
- Overview, short(!) mission statements about catalog services implementation (all):
- What are the experiences so far?
- What are the requirements?
- What are possible alternatives, how should we/NSDIs proceed?
