Welcome

This site contains information, documentation, and access to downloadable software including and related to the Tupelo semantic content repository, NCSA (http://www.ncsa.uiuc.edu/) software for managing data and metadata.

Tupelo is being developed by Joe Futrelle (http://www.ncsa.uiuc.edu/People/futrelle), Joel Plutchak, and Jeff Gaynor at NCSA. The development effort was initially primarily supported by the NEES (http://www.nees.org/) project.

About Tupelo 2

Tupelo is a data and metadata management system based on semantic web technologies. Tupelo provides a variety of generic utilities for managing large RDF graphs using best-of-breed RDF database implementations such as Jena (http://jena.sourceforget.net/) and Sesame (http://www.openrdf.org/).

Tupelo is designed for archiving large-scale, complex scientific data and metadata collections. It is also suitable for more conventional digital libraries containing Dublin Core (http://dublincore.org/) or other standard digital library metadata schemas. Its RDF-based metadata framework can support a wide variety of schemas, from simple, flat-namespace schemas such as Dublin Core, to hierarchical models derived from XML Schema (http://www.w3.org/XML/Schema), to more web-like models derived from RDF (http://www.w3.org/RDF/) variants such as RSS (http://en.wikipedia.org/wiki/RSS).
