What is the difference between BOAI and the Open Archives Initiative?
The Open Archives Initiative (OAI) is a protocol for collecting metadata about data files residing in separate archives. When the protocol is used by data services like search engines, they can process the data in separate archives as if they resided in just one archive. (In the technical jargon, the metadata harvesting protocol supports interoperability.) The BOAI supports OAI for all open-access literature, but BOAI is not part of OAI or vice versa.
