Talk:Geodata Discovery Working Group

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

  • Chairs: Stefan F. Keller (organization) and Tom Kralidis
  • Participants: curr. expected about 8

  • 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?
  • Approaches:
    • owscat (Tom Kralidis)

Map Libraries

Why doesn't someone look into the holdings and records of map libraries? DK Flatla 04:35, 22 September 2006 (CEST)

I'm not sure whether you mean classic paper map libraries? If yes, that's exactly where Dublin Core and OAI-PMH come from! -- SFK 08:46, 22 September 2006 (CEST)
