Tupelo 2

Overview

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 and Sesame .

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 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, to more web-like models derived from RDF variants such as RSS.

Tupelo's Main Features

• WebDAV
• URIQA
• plain filesystem
• MySQL
• PostgreSQL
• Derby

Server-side support for content API's including

• URIQA
• RSS

Abstract "Context"/"Operator" model supporting

• Writing and querying RDF data to heterogeneous stores
• Reading and writing binary streams
• Merging/mirroring heterogeneous RDF and content stores
• Declarative specification and procedural execution of RDF transformation rules
• Rudimentary ability to execute SPARQL queries and SWRL rules
