Authors: Pascal Hitzler, Markus Krötzsch, Sebastian Rudolph.
This document is written for those who are familiar with OWL 1 and require an introduction to the differences between OWL 1 and OWL 2. The list of changes below is fairly complete but not exhaustive. It reflects the status of the discussions on OWL 2 as of 8th of April, 2009.

Digital Version of the famous Encyclopédie....
The Encyclopédie ou Dictionnaire raisonné des sciences, des arts et des métiers, par une Société de Gens de lettres was published under the direction of Diderot and d'Alembert, with 17 volumes of text and 11 volumes of plates between 1751 and 1772. Containing 74,000 articles written by more than 130 contributors, the Encyclopédie was a massive reference work for the arts and sciences, as well as a machine de guerre which served to propagate the ideas of the French Enlightenment. The impact of the Encyclopédie was enormous. Through its attempt to classify learning and to open all domains of human activity to its readers, the Encyclopédie gave expression to many of the most important intellectual and social developments of its time.
Aufrührerisches im Lexikon? Heute schwer vorstellbar, wenn der Brockhaus im Schrank verstaubt. Doch als Denis Diderot 1751 seine Encyclopédie beginnt, geht es nicht nur um ein Mammutwerk. Auch an den Zuständen vor der französischen Revolution will er rütteln. So findet sich unter dem Stichwort "Menschenfresser" ein bitterböser Verweis: "Siehe auch Eucharistie, Kommunion, Altar usw."

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:
This specification defines the HTML microdata mechanism. This mechanism allows machine-readable data to be embedded in HTML documents in an easy-to-write manner, with an unambiguous parsing model. It is compatible with numerous other data formats including RDF and JSON.
