TopQuadrant Offers Free Semantic Web Modeling Tool

SAN JOSE, CA, Jun 16 (MARKET WIRE) --
SEMANTIC TECHNOLOGY CONFERENCE 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
