C'est vrai que ce talk est super. Toute la valeur vient du faite d'avoir rassemblé ces données au même endroit. – nicolas
Linked Data. An introductory overview of Linked Open Data in the context of cultural institutions.
In computing, linked data (often capitalized as Linked Data) describes a method of publishing structured data so that it can be interlinked and become more useful. It builds upon standard Web technologies such as HTTP, RDF and URIs, but rather than using them to serve web pages for human readers, it extends them to share information in a way that can be read automatically by computers. This enables data from different sources to be connected and queried. Tim Berners-Lee, director of the World Wide Web Consortium, coined the term in a design note discussing issues around the Semantic Web project. Principles 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. DBpedia allows users to query relationships and properties associated with Wikipedia resources, including links to other related datasets. DBpedia has been described by Tim Berners-Lee as one of the more famous parts of the decentralized Linked Data effort. Background The project was started by people at the Free University of Berlin and the University of Leipzig, in collaboration with OpenLink Software, and the first publicly available dataset was published in 2007.
It is made available under free licences, allowing others to reuse the dataset. Dataset 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. Barack Obama's CIO pushes for Web 2.0 government. Barack Obama, US president, has appointed a new chief information officer who has already said he will act aggressively to change the federal government's use of IT.
Vivek Kundra, the new federal CIO and currently chief technology officer at the District of Columbia, said he will adopt consumer technology and ensure the government data is open and accessible. Kundra also wants to use technology such as cloud computing to attack the government's culture of big-contract boondoggles and its hiring of contractors who end up "on the payroll indefinitely". Kundra, in a conference call on Thursday with reporters shortly after President Barack Obama named him as federal CIO said one of his first projects is to create a data.gov web site to "democratise" the federal government's vast information treasures by making them accessible in open formats and in feeds that can be used by application developers.

Ce besoin de voyage est d’autant plus fort que le coût d’un trajet numérique Boston / Bangalore tend vers zéro. Et puis après tout, n’est ce pas dans notre nature de partager, copier, diffuser l’information ? Nous sommes des primates, nous apprenons par mimétisme. Et dans un monde hautement interconnecté et numérique, où il n’a jamais été aussi simple d’apprendre et de partager, notre nature reprend le dessus. Je crois profondément que nous sommes à l’aube d’une ère nouvelle. OpenStreetMap.
Du coup j'ai rajouté pearltrees ;) – nicolas
