Semantic Web Development

摘要

The work funded by DARPA and done by MIT and W3C under DAML Agent Markup Language (DAML) project between 2002 and 2005 provided key steps in the research in the Semantic Web technology, and also played an essential role in delivering the technology to industry and government in the form of open W3C standards. The Web Ontology Language (OWL), a W3C Recommendation, is widely adopted in industry and academia and standardization work has started on a Rule Interchange Format (RIF). The chief products of research were the development of the SWELL logic language, instantiated as the Notation3 language; the experience of its use, and the software tools such as cwm developed around it. These tools, released as open source, have formed an on-ramp for many newcomers to the semantic web technology. Despite these successes, the Semantic Web has a long way to go - both in terms of research on the higher layers and in deployment. The report discusses factors which may have affected deployment speed, and concludes with an outline of ongoing efforts which would be appropriate.
