We are pleased to announce the release of the BETA version of the
OAI-PMH v.2.0:

* The BETA protocol document is available at
http://www.openarchives.org/OAI/2.0/openarchivesprotocol.htm .
* Linked from the protocol document is also a migration document
pointing out the major differences between the experimental 1.0/1.1
version of the protocol and version 2.0, which is released as a stable
* Also linked from the protocol document are Implementation Guidelines,
covering a broad range of topics related to protocol implementation.

This BETA release comes after 16 months of worldwide experimentation
with version 1.x of the protocol, an 8 month revision process by the
OAI-tech group, and 2 months of alpha testing.  We feel confident about
the quality of the resulting specification.  We encourage discussion of
the specification on the oai-implementers list to help us further
improve the specification. Also, we encourage you to inform the list
about v.2.0BETA conformant data provider implementations, when they
become available.  We expect this to be useful to support other

The full release of the OAI-PMH v.2.0 is expected around the middle of
June 2002.  Up until that time we hope to keep the functionality of the
beta specification stable, restricting changes to textual clarifications
and corrections.

Below, preliminary information is provided regarding OAI-PMH v.2.0
conformant tools that will become available by or soon after June 1st
2002.  They will be listed on the Open Archives website as they become
