Ce billet livre une réflexion intéressante sur l’utilisation, les potentialités et les limites du web sémantique avec l’exemple du New York Times.
Notamment, il apparaît indispensable de créer des normes, ou des convention, par métier, pour nommer les relations.
« Creating standards is the next step in the process towards building a more connected web. Working to further connect information on the web, The World Wide Web Consortium (W3C), among other communities, continues to develop standards for the Semantic Web, explained Sandhaus, including RDFa, which enables users to embed rich metadata, such as title, author and date information, within web documents. This allows users to call out meanings for specific portions of a webpage, making the information more usable on the greater web.
The problem with RDFa, though, is that different organizations can use it to develop different naming systems for the same pieces of data, says Sandhaus. In the media world, for example, a “headline” could also be called a “title,” or even “Schlagzeile” (in German) or “intestazione” (in Italian).
The New York Times is hoping to alleviate this problem. As of October 2010, The Times, in collaboration with the International Press Telecommunications Council, is working on creating a standard within the publishing industry to express structural metadata within HTML — this framework is called rNews. With this standard, search engines, aggregators and social sites, for example, will have access to the data, making it more useful to the web at large. The project has only just begun, but Sandhaus expects to have more details about its direction in coming months. »
