Bienvenue sur le portail de la cartographie sémantique. Metaweb. Semantic Web roadmap. Up to Design Issues A road map for the future, an architectural plan untested by anything except thought experiments. This was written as part of a requested road map for future Web design, from a level of 20,000ft. It was spun off from an Architectural overview for an area which required more elaboration than that overview could afford. Necessarily, from 20,000 feet, large things seem to get a small mention.
It is architecture, then, in the sense of how things hopefully will fit together. This document is a plan for achieving a set of connected applications for data on the Web in such a way as to form a consistent logical web of data (semantic web). Introduction The Web was designed as an information space, with the goal that it should be useful not only for human-human communication, but also that machines would be able to participate and help. It follows the note on the architecture of the Web, which defines existing design decisions and principles for what has been accomplished to date. 1999: The WWW Proposal and RDF. Initial version: 1999-11-12, Dan Brickley danbri@w3.org Revised: March 2001 Status: This is a work in progress, and an early release of the document for feedback from the RDF Interest Group. It is intended as an informal discussion document, and is not a formal publication of any working group, or of the W3C itself.
See the Semantic Web Activity pages for information about current W3C work in this area. Although the HTML is valid and the RDF/XML parses successfully with SiRPAC, W3C's Java RDF parser, readers are cautioned that the Javascript demonstration referenced here will only work on some platforms. General comments on this work-in-progress should be sent to the RDF Interest Group; bug reports should be sent to the author. Information Management: Then and Now The original proposal of the WWW from 1989 included a figure showing how information about a Web of relationships amongst named objects could unify a number of information management tasks.
(CERN figure from WWW proposal) DBpedia. DBpedia ( from "DB" for "database" ) is a project aiming to extract structured content from the information created as part of the Wikipedia project. This structured information is then made available on the World Wide Web.[1] DBpedia allows users to query relationships and properties associated with Wikipedia resources, including links to other related datasets.[2] DBpedia has been described by Tim Berners-Lee as one of the more famous parts of the decentralized Linked Data effort.[3] Background[edit] The project was started by people at the Free University of Berlin and the University of Leipzig, in collaboration with OpenLink Software,[4] and the first publicly available dataset was published in 2007.
It is made available under free licences, allowing others to reuse the dataset. Dataset[edit] From this dataset, information spread across multiple pages can be extracted, for example book authorship can be put together from pages about the work, or the author. Examples[edit] Use cases[edit]
