The main features of TopBraid Composer™ 2.0 are:

• Customizable Inference Engines (reasoners) – Users can select from a catalog of available inference engines and arrange them to execute in a delegation chain. Allows SPARQL queries or rules to run on top of a description logic reasoner (such as Pellet).
• Information Visualization and Mash-up Facilities – Support for RDFa and GRDDL allows metadata to be embedded into existing HTML pages for the creation of mash-up applications that extract information from multiple sources. RSS and Atom feeds are also supported. Geographical location support using embedded Google maps allows users to visualize and edit the locations of geographical entities.
• Support for the emerging OWL 1.1 extensions – New expressivity in the OWL 1.1 web ontology language can be used to build richer ontology models.
• Ontology Mapping Support – Ontology translation between heterogeneous information sources, such as different databases.
• Integration with XML, Relational Database and Other Legacy Datasources - Conversion of UML models, XML schema, XML documents and spreadsheets into RDF/OWL. Ability to import data directly from legacy relational databases. Legacy database tables and rows are converted on-the-fly. Generation of XML Schema from RDF/OWL.
• Flexible Triplestore Integration – Support to optionally connect to Jena, Sesame and Oracle 11g, and other open source and commercial triplestore solutions and products.
• Multi-user Mode and Modular Ontologies – Allows a number of people to edit an ontology at the same time, across the internet. The tool supports to modularize ontologies into reusable building blocks that can be assembled dynamically.
• Customized Content Layouts – Users can configure the layout of forms and other content to enable user-friendly and domain-specific editing.
