Anzo includes both an open source enterprise-featured RDF quad store and a sophisticated service oriented, semantic middleware platform that provides support for multiple users, distributed clients, offline work, real-time notification, named-graph modularization, versioning, access controls, and transactions. Developers will discover a host of features we believe are necessary for the creation of sophisticated applications based on W3C semantic technology standards like OWL, RDF and SPARQL.

exai is an open source project to create an artificial intelligence. The approach is to first construct an English dialog system whose initial goals are to acquire linguistic and common sense skills that improves its own performance. The project is hosted at SourceForge and has already released the largest freely available English lexicon in RDF.

Sesame is an open source framework for storage, inferencing and querying of RDF data.

SIMILE seeks to enhance inter-operability among digital assets, schemata/vocabularies/ontologies, metadata, and services. A key challenge is that the collections which must inter-operate are often distributed across individual, community, and institutional stores. We seek to be able to provide end-user services by drawing upon the assets, schemata/vocabularies/ontologies, and metadata held in such stores. SIMILE will leverage and extend DSpace, enhancing its support for arbitrary schemata and metadata, primarily though the application of RDF and semantic web techniques. The project also aims to implement a digital asset dissemination architecture based upon web standards. The dissemination architecture will provide a mechanism to add useful "views" to a particular digital artifact (i.e. asset, schema, or metadata instance), and bind those views to consuming services.

Today, we present a screencast exhibiting Protégé — a free, open source ontology editor and knowledge-base framework developed by Stanford Center for Biomedical Informatics Research at the Stanford University School of Medicine. In this screencast, we show you how to develop a useful Semantic Web-ready application in just minutes. You will learn how to model a very simple ontology in OWL (the Web Ontology Language).
