Cool URIs for the Semantic Web

by 2 others
The Resource Description Framework RDF allows the users 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 (Uniform Resource Identifiers) are very important, forming the link between RDF and the Web. This document presents guidelines for their effective use. It discusses two strategies, called 303 URIs and hash URIs. It gives pointers to several Web sites that use these solutions, and briefly discusses why several other proposals have problems.

by 6 others, 4 comments
Bien qu’elle ait été lancée par le W3C dés 1998, l’initiative du Web sémantique [1] reste encore aujourd’hui marginale face aux problématiques courantes du Web, comme par exemple la publication de contenu.
