Resource Description Framework (RDF) is a standard for describing resources on the web. This guide contains links to many RDF resources including examples, documents, software, tools and projects that use it.
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.
