NCSA Releases Tupelo for Metadata Archiving
The Digital Library Technologies group at the National Center for Supercomputing Applications (NCSA) is pleased to announce the release of Tupelo 1.0, a data and metadata archiving system. Earlier versions of Tupelo were previously available as part of the NEESgrid software distribution. Tupelo is designed to support archiving and configuration management for complex metadata objects and files. Objects and files can be created, updated, organized into semantic networks, and secured. In addition, metadata objects can be searched and retrieved based on the values of arbitrary, user-defined attributes. Tupelo supports the description of metadata ontologies in RDF-OWL and secure, remote access using Grid Services and GridFTP. The Digital Library Technologies group is currently working with a pair of teams at NCSA and the University of Illinois at Urbana- Champaign to use Tupelo to archive molecular dynamics simulation data and digital music collections.
