getSchema's RDFa Lite extractor is a REST web service to extract RDF [1] data from RDFa Lite [2] annotations and provide the semantic information as N-Triples [5] , N3 [3] and JSON [4].
This is a specification of a precise semantics, and corresponding complete systems of inference rules, for the Resource Description Framework (RDF) and RDF Schema (RDFS).
RDF Translator is a multi-format conversion tool for structured markup. It provides translations between data formats ranging from RDF/XML to RDFa or Microdata. The service allows for conversions triggered either by URI or by direct text input. Furthermore it comes with a straightforward REST API for developers.
This site is a complementary effort by people from the Linked Data community to support Schema.org deployment and usage with a special focus on Linked Data:
The Resource Description Framework RDF allows you to describe web documents and resources from the real world—people, organisations, things—in a computer-processable way. Publishing such descriptions on the web creates the semantic web. URIs are very important as the link between RDF and the web. This article presents guidelines for their effective use.

In March 1989, Tim Berners-Lee submitted a proposal for an information management system to his boss, Mike Sendall. ‘Vague, but exciting’, were the words that Sendall wrote on the proposal, allowing Berners-Lee to continue.
