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
