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 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
 * Chairs: Stefan F. Keller (organization) and Tom Kralidis
 * 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?


 * 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
