XML.com: SIMILE: Practical Metadata for the Semantic Web: "Browsing digital libraries today can be a difficult process of navigating through different interfaces and different terminologies for each collection visited. The SIMILE Project is working to make it easier to wander from collection to collection and, more generally, to find your way around in the Semantic Web.
SIMILE (an acronym for Semantic Interoperability of Metadata In unLike Environments) was originally motivated by DSpace, a repository for storing, indexing, preserving, and redistributing digital assets, jointly developed by Hewlett-Packard Research Labs and the MIT Libraries. DSpace is a tool used by many research-producing organizations, and often by their libraries, to manage digital data and for researchers to find that data. DSpace is available as open source software and is used and supported by the DSpace Federation community."
