The National Science Digital Library Core Integration team at Cornell University has released a partial version of NCore, a "general platform for building semantic and virtual digital libraries united by a common data model and interoperable applications," which is built upon Fedora.
Here's an excerpt from the NSDL posting:
The NCore platform consists of a central repository built on top of Fedora, a data model, an API, and a number of fundamental services such as full-text search or OAI-PMH. Innovative NSDL services and tools that empower users as content creators are now built on, or transitioning to, the NCore platform. These include: the Expert Voices blogging system (http://expertvoices.nsdl.org/);the NSDL Wiki (http://wiki.nsdl.org/index.php/NSDL_Wiki); the NSDL OAI-PMH metadata ingest aggregation system; the OAI-PMH service for distributing public NSDL metadata; the NSDL Collection System (NCS), derived from the DLESE Collection system (DCS); the NSDL Search service, and the OnRamp content management and distribution system (http://onramp.nsdl.org).
Because NCore is a general Fedora-based open source platform useful beyond NSDL, Core Integration developers at Cornell University have made the repository and API code components of NCore available for download at the NCore project on Sourceforge (http://sourceforge.net/projects/nsdl-core). Over the next six months, NSDL will release the code for major tools and services that comprise the full NCore suite on SourceForge.
