From the MOAI site: "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. The MOAI software can aggregate content from different sources, transform it and store it in a database. The contents of this database can then be published in many separate OAI feeds, each with its own configuration. MOAI is a standalone system, so it can be used in combination with any repository software that comes with an OAI feed such as Fedora Commons, EPrints or DSpace. It can also be used directly with an SQL database or just a folder of XML files.
...the MOAI software makes it as easy as possible to add or modify parts of your repository (OAI) services stack. It tries to do this without sacrificing power, and encouraging the re-use of components.

I remember when pyoai first came out a few years back, I think there were some zope integration components alongside it. It's great to see that this project is still in use and still being improved.

More details about getting it and installing it are on installing MOAI page, and a copy of the 1.0 source tarball is attached.
