RDFa Distiller and Parser. This distiller corresponds to the RDFa 1.0 specification. In 2012, W3C has published an updated version of that specification, called RDFa Core 1.1. A new distiller, processing RDFa 1.1 content, has been implemented which suprecedes this one. Note that the new distiller can also process RDFa 1.0 content (there are some minor incompatibilities) if the XHTML+RDFa file uses the right (RDFa 1.0) DTD and/or the @version attribute. Users are advised to migrate to RDFa 1.1 in general, including the RDFa 1.1 distiller. If you intend to use this service regularly on large scale, consider downloading the package and use it locally. Storing a (conceptually) “cached” version of the generated RDF, instead of referring to the live service, might also be an alternative to consider in trying to avoid overloading this server… What is it? RDFa is a specification for attributes to be used with XHTML or SVG Tiny to express structured data. PyRdfa is a server-side implementation of RDFa.

Introduction FOAF-a-matic is a simple Javascript application that allows you to create a FOAF ("Friend-of-A-Friend") description of yourself.
You can read more about FOAF in Edd Dumbill's "XML Watch: Finding friends with XML and RDF" article, at the FOAF homepage on RDFWeb, and also the FOAF vocabulary description. In short though, FOAF is a way to describe yourself -- your name, email address, and the people you're friends with -- using XML and RDF. The FOAF-a-Matic is being provided as a quick and easy way for you to create your own FOAF description. Note: none of the information you enter in this page is used or stored in any way. If you have comments about this application, or further questions about FOAF, why not join the RDFWeb-dev mailing list?
Update: I'm currently writing the FOAF-a-Matic Mark 2 a desktop application for creating and managing your FOAF data. People You Know Tell FOAF-a-matic about some people you know.

Abstract This document defines a set of extension attributes for the Web Services Description Language and XML Schema definition language that allows description of additional semantics of WSDL components. The specification defines how semantic annotation is accomplished using references to semantic models, e.g. ontologies. Semantic Annotations for WSDL and XML Schema (SAWSDL) does not specify a language for representing the semantic models. Instead it provides mechanisms by which concepts from the semantic models, typically defined outside the WSDL document, can be referenced from within WSDL and XML Schema components using annotations.
Status of this Document This section describes the status of this document at the time of its publication. Other documents may supersede this document. This is the W3C Recommendation of the Semantic Annotations for WSDL and XML Schema specification. The Working Group released an implementation report and a test suite. Table of Contents Appendices 1.
Concept. Ontology for Media Resources 1.0. This section describes the status of this document at the time of its publication. Other documents may supersede this document. A list of current W3C publications and the latest revision of this technical report can be found in the W3C technical reports index at This document has been reviewed by W3C Members, by software developers, and by other W3C groups and interested parties, and is endorsed by the Director as a W3C Recommendation. It is a stable document and may be used as reference material or cited from another document. W3C's role in making the Recommendation is to draw attention to the specification and to promote its widespread deployment. This document is based upon the Ontology for Media Resources 1.0 Proposed Recommendation of 29 November 2011. 1 Introduction This document defines the Ontology for Media Resources 1.0.
Ideally, the mappings defined in this document would preserve the semantics of a metadata item across metadata formats. 3 Terminology.

Included are the fifteen terms of the Dublin Core Metadata Element Set, which have also been published as IETF RFC 5013 [RFC5013], ANSI/NISO Standard Z39.85-2007 [NISOZ3985], and ISO Standard 15836:2009 [ISO15836].

Introduction The Dublin Core Metadata Element Set is a vocabulary of fifteen properties for use in resource description. The name "Dublin" is due to its origin at a 1995 invitational workshop in Dublin, Ohio; "core" because its elements are broad and generic, usable for describing a wide range of resources. The fifteen element "Dublin Core" described in this standard is part of a larger set of metadata vocabularies and technical specifications maintained by the Dublin Core Metadata Initiative (DCMI).
The full set of vocabularies, DCMI Metadata Terms [DCMI-TERMS], also includes sets of resource classes (including the DCMI Type Vocabulary [DCMI-TYPE]), vocabulary encoding schemes, and syntax encoding schemes. The terms in DCMI vocabularies are intended to be used in combination with terms from other, compatible vocabularies in the context of application profiles and on the basis of the DCMI Abstract Model [DCAM].

SKOS Simple Knowledge Organization System Namespace Document - HTML Variant, 18 August 2009 Recommendation Edition. Status of this Document This document describes the schema available from the SKOS namespace. Introduction The Simple Knowledge Organization System (SKOS) is a common data model for sharing and linking knowledge organization systems via the Semantic Web.This document provides a brief description of the SKOS Vocabulary. For detailed information about the SKOS Recommendation, please consult the SKOS Reference [SKOS-REFERENCE] or the SKOS Primer [SKOS-PRIMER]. SKOS Schema Overview The following table gives a non-normative overview of the SKOS vocabulary; it replicates a table found in the (normative) SKOS Reference [SKOS-REFERENCE].

[read more] Alignment between SKOS and new ISO 25964 thesaurus standard (2012-12-13) ISO 25964-1, published in 2011, replaced the previous thesaurus standards ISO 2788 and ISO 5964 (both now withdrawn). Members of the Working Group responsible for ISO 25964 have gone on to consider the implications for SKOS users. They have developed a set of linkages between the elements of the ISO 25964 data model and the ones from SKOS, SKOS-XL, and MADS/RDF. This new "Correspondence between ISO 25964 and SKOS/SKOS-XL models" document can be accessed at and replaces the previous table presented in the SKOS Primer.

Les logiques de description aussi appelé logiques descriptives (LD) sont une famille de langages de représentation de connaissance qui peuvent être utilisés pour représenter la connaissance terminologique d'un domaine d'application d'une manière formelle et structurée. Le nom de logique de description se rapporte, d'une part à la description de concepts utilisée pour décrire un domaine et d'autre part à la sémantique basée sur la logique qui peut être donnée par une transcription en logique des prédicats du premier ordre.
La logique de description a été développée comme une extension des frames et des réseaux sémantiques, qui ne possédaient pas de sémantique formelle basée sur la logique. Origines et applications des logiques de description[modifier | modifier le code] Définition des logiques de description[modifier | modifier le code] La plupart des logiques de description divisent la connaissance en deux parties : , où Définition 1 : Soit pour .
