First Free Semantic Web Editing and Querying Tool with Object-oriented Rule Modeling and RDFa Import

SEMANTIC TECHNOLOGY CONFERENCE 2009, SAN JOSE, Calif. – June 16, 2009 - TopQuadrant(tm), the global leader in Semantic Web application development technology, today announced TopBraid Composer(tm) Free Edition, a professional editing and querying tool for Semantic Web technology that allows users to view, share and query RDF data. TopBraid Composer Free Edition is a light version of TopBraid Composer, the leading commercial Semantic Web ontology modeling environment.

For the first time, technically savvy users can build enterprise-class Semantic models, design and edit Semantic queries, create Semantic business rules and share their creations with others – for free. Users can also import RDFa markup used to publish machine-readable data on the web. TopBraid Composer Free Edition simplifies the process of linking business logic to domain models by providing an object-oriented rule model. This object-oriented approach provides users with a more natural way of expressing knowledge, behavior and rules.

"There is fast-growing interest from all industries to understand the unique data quality, data integration and dynamic discovery benefits that Semantic Web technology has to offer," said Holger Knublauch, VP of product development at TopQuadrant. "But we recognize that unfamiliarity with W3C Semantic Web standards and cost are two obstacles prohibiting many organizations from starting a Semantic Web project. By offering a free version of our modeling environment, we are removing these barriers."

TopBraid Composer Free Edition shortens the learning curve for starting Semantic Web projects by using Eclipse, a popular open source development environment that is familiar to a broad set of developers and technically savvy people. In addition to support for W3C standards such as RDF, OWL and SPARQL, TopBraid Composer Free Edition also includes SPIN (SPARQL Inferencing Notation), the first Semantic Web language with an explicit object-oriented rule model that can link business logic and domain models. SPIN eliminates the need to learn OWL to link RDF resources with associated queries or to share and reuse queries.

"Support for RDFa from industry leaders such as Google and Yahoo is an important step in the adoption of Semantic Web technologies," added Knublauch. "We’ve included RDFa import capabilities in the free version of TopBraid Composer as a way to facilitate the use of RDFa tags within enterprise-class Semantic Web projects and applications."

TopBraid Composer Free Edition offers all of the functionality needed to view, share and query RDF data to start an enterprise-class Semantic Web project. Users can:

  • Load, edit and save RDF files in RDF/XML, N3 and N-triple files
  • Define ontologies using form-based editors
  • Create and execute SPARQL queries
  • Create and execute SPIN rules
  • Import RDFa markup from web pages
