Talk:Geodata Discovery Working Group

Proposal

This is 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)

Agenda

• Overview, short(!) statements of all about catalog services implementation:
  • What are the experiences so far?
  • What are the requirements?
  • What are possible alternatives, how should we/NSDIs proceed?

• Approaches:
  • owscat (Tom Kralidis)
  • OAI approach (Stefan F. Keller)
  • Google scraping (Paul Ramsey)
  • Client programming (Jody Garnett)

• CSW Software:
  • GeoNetwork (Jeroen Ticheler?)
  • deegree (someone?)

• Models for Metadata Management and for Exchange
  • CSW 2.1 ebRIM (Raj Singh?) => Metadata Management
  • FGDC extended (Jo Walsh?) => Metadata Management
  • Dublin Core extended (Stefan) => Metadata Exchange

• Discussion of pros and cons of approaches (all)
  • Timelines
  • Way forward
