Infrae has released MOAI 1.0.7, a standalone OAI-PMH server that can “can be used in combination with any repository software that comes with an OAI feed.”
Here's an excerpt from the announcement:
MOAI is a platform for aggregating content from different sources, and publishing it through the Open Archive Initiatives protocol for metadata harvesting. It's been built for academic institutional repositories dealing with relational metadata and asset files. . . .
More specifically MOAI has the ability to:
- Harvest data from different kinds of sources
- Serve many OAI feeds from one MOAI server, each with their own configuration
- Turn metadata values into OAI sets on the fly, creating new collections
- Use OAI sets to filter records shown in a feed, configurable for each feed
- Work easily with relational data (e.g. if an author changes, the publication should also change)
- Simple and robust authentication through integration with the Apache webserver
- Serve assets via Apache while still using configurable authentication rules
