Microsoft has released the Research-Output Repository Platform Version 1.0, which is called "Zentity."
Here's an excerpt from the announcement (includes download link):
The platform is based on Microsoft’s technologies (SQL Server 2008 and .NET Framework version 3.5 SP1) hence taking advantage of their robustness, their quality support infrastructure, and the plethora of developer-focused tools and documentation.. . . The platform focuses on the management of academic assets—such as people, books/papers, lectures, presentations, videos, workflows, datasets, and tags — as well as the semantic relationships between them. In this latest release, developers can declaratively (or at runtime) easily introduce their own asset and relationship types. Support for various formats and services such as full-text search, OAI-PMH, RSS and Atom Syndication, BibTeX import and export, SWORD, AtomPub, RDFS, and OAI-ORE are included as part of the distribution.
