OAI Best Practices wiki

The Digital Library Federation (DLF), with help from the National Science Digital Library, maintains an OAI Best Practices wiki.  (Thanks to Charles Bailey.)  From the wiki front page: 

Workspace for the DLF and NSDL working group to define best practices for the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) and for the metadata shared/exposed by its use. We also aspire to discover or create methods to overcome impediments to more widespread use of OAI for digital library aggregation.

This workspace is intended to be the staging area for development of documents, etc. for the target audience consisting of OAI data providers, OAI service providers, metadata creators, etc.
