Explorator is a tool for exploring RDF data by direct manipulation. Explorator’s web interface allows users to explore a semi-structured RDF database to both gain knowledge and answer specific questions about a domain, through browsing, search, and exploration mechanisms.
A simple but powerful service that delivers RDF-based structured descriptions of Web addressable resources (documents or real world objects) in a variety of formats through Generic HTTP URIs.
While Lucene has long offered these capabilities, its native capabilities are not intended for large semi-structured document collections (or documents with very different schemas). For this reason we developed SIREn - Semantic Information Retrieval Engine - a Lucene plugin to overcome these shortcomings and efficiently index and query RDF, as well as any textual document with an arbitrary amount of metadata fields.
Universal Wikipedia tags are often too long and too hard to enter and the exact name of a tag has to be known beforehand. Furthermore, tags are personal items – a private association to some concept.
AWWSW is the somewhat facetiously named "Architecture of the World Wide Semantic Web" Task Force. This is a task force created in a November 2007 TAG meeting to look into the semantics of HTTP interactions.
