Simple Catalog Interface

This page helps document a conversation in the Geodata Committee about developing simple protocols for discovering and syndicating metadata describing where geodata is available. The conversation is visible and joinable through the osgeo geodata mailing list (archives for Aug. 2006)

Stefan Keller wrote an excellent overview describing some of the background to why there is a felt need for a simple metadata exchange/search interface

Requirements

• we want a simple web interface
• we want it to be as existing-standards-compliant as possible
• we want it to be very easily syndicatable and contributable as possible
• we not only want to register a static resource but also web services

Web addressable interfaces
