Open Archives Metadata Harvesting Protocol

• Standards for efficient dissemination of content.

• Not just for archives!

• Simpler than Z39.50 - based on Harvest protocols and experience with union catalogs

Federated search services

• servers gather metadata via HTTP, normalize, remove dupes, etc.

• user queries service via HTTP

Dublin Core is the common metadata format

• others must be transportable in XM L

• example: e-print archives include author affiliation, journal name, etc.

Does not cover authentication, trust, security, use policies, etc.

Does not do fulltext search automatically
