Microsoft Research has released Research-Output Repository Platform Beta 1 and Savas Parastatidis, Architect in the Technical Computing @ Microsoft group, has released OfficeSWORD.
Here's an excerpt from the Research-Output Repository Platform's download page:
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 documentation. New applications on top of the platform can be developed using any .NET language and the Visual Studio 2008 SP1 environment. The platform focuses on the management of research assets—such as people, papers, lectures, workflows, data, and tags—as well as the semantic relationships between them. Support for various services such as full-text search, OAI-PMH, RSS and Atom Syndication, BibTeX import and export, SWORD, AtomPub, and OAI-ORE are included as part of the distribution.
Here's an excerpt from "SWORD Plugin for Word 2007":
During discussions with the Fedora Commons and DSpace communities, it was suggested to us that an open source plugin for Word 2007 that talks with any repository service through SWORD would be a good idea. I finally managed to put some time aside to develop such a plugin and upload it to Codeplex. You'll need VS.NET 2008 SP1 to load the code and run it (there is currently no separate installer I am afraid but we are working on one).
