The Los Alamos National Laboratory has released of aDORe Archive, open-source, OAI-compliant archiving software. From the site:
The aDORe Archive is a write-once/read-many storage approach for Digital Objects and their constituent datastreams. The approach combines two interconnected file-based storage mechanisms that are made accessible in a protocol-based manner. First, XML-based representations of multiple Digital Objects are concatenated into a single, valid XML file named an XMLtape. The creation of indexes for both the identifier and the creation datetime of the XML-based representation of the Digital Objects, facilitates OAI-PMH-based access. Second, ARC files, as introduced by the Internet Archive, are used to contain the constituent datastreams of the Digital Objects in a concatenated manner. An index for the identifier of the datastream facilitates OpenURL-based access. The interconnection between an XMLtape and its associated ARC file(s) is provided by conveying the identifiers of these ARC files as administrative information in the XMLtape, and by including OpenURL references to constituent datastreams of a Digital Object in the XML-based representation of that Digital Object stored in the XMLtape. The aDORe Archive allows for the storage of mutliple XMLtapes and ARC files through the introduction of OAI-PMH compliant XMLtape and ARCfile registries.
PS: aDORe clearly has special features that set it apart from other archiving packages. To someone more technically proficient than I, the site may suggest the special uses aDORe supports that the other packages don't. But I'm still trying to figure them out.

The open access movement:
Putting peer-reviewed scientific and scholarly literature
on the internet. Making it available free of charge and
free of most copyright and licensing restrictions.
Removing the barriers to serious research.
