Today we released Places , a new way for people on Facebook to share where they are, see where their friends have checked in, and discover interesting places nearby. As part of the rollout, we're making Places available to developers via the Graph API , so you can integrate location features into your own mobile applications, websites, and applications on Facebook. Once you are granted user permission, you can access a user and their friends' check ins on their behalf. More information on the Graph API can be found here . In the coming months, we will offer additional location features through the Graph API and the Open Graph protocol, including the ability to check in with Facebook through your application and discover places nearby. We're working with an initial set of partners including Gowalla , foursquare , Yelp and Booyah's InCrowd to enable users to share check-ins on Facebook.

Open Graph protocol
At Facebook's core is the social graph; people and the connections they have to everything they care about. Historically, Facebook has managed this graph and has expanded it over time as we launch new products (photos, places, etc.). In 2010, we introduced an early version of Open Graph, an extension of the social graph, via the Open Graph protocol , to include 3rd party web sites and pages that people liked throughout the web.
RDFa inside
The Open Graph protocol enables any web page to become a rich object in a social graph. For instance, this is used on Facebook to allow any web page to have the same functionality as any other object on Facebook. While many different technologies and schemas exist and could be combined together, there isn't a single technology which provides enough information to richly represent any web page within the social graph.
Implementing
We shared an update last week about the products launched at f8 and that over 50,000 websites have already implemented the new social plugins to become more personalized. We created the Open Graph protocol in support of social plugins as part of our efforts to help realize the vision of the Open Graph. Any website can implement the Open Graph protocol. It allows any web page to become a rich object in any social graph, making it easy to find what people are liking across the Web -- from a movie to a blog. To start integrating the Open Graph protocol into your Web pages, read our documentation . Last week, Facebook's David Recordon gave a presentation at the WWW Conference explaining the design decisions behind the Open Graph protocol, which is embedded below.

Do they really want a Semantic Web?
Two weeks ago, Facebook has announced a major new initiative called Facebook Open Graph. This is an attempt to not only re-imagine Facebook, but in a lot of ways, an attempt to re-define how the Web works. We wrote in details about the implications of this move for all interested parties. A big part of the announcement is Facebook's vision of a consumer Semantic Web. In this new world, publishers have an incentive to annotate pages by marking up activities, events, people, movies, books, music and more. The proper markup, would in turn, lead to a much more interconnected Web - people would be connected with each other across websites and around the things they are interested in.Two weeks ago, Facebook has announced a major new initiative called Facebook Open Graph.

Retour le 21 avril au soir : Facebook organise l'événement F8 au cours duquel il va annoncer les évolutions de sa plate-forme à destination des développeurs. A titre personnel, je n'ai pas vu l'annonce dont je n'ai a priori rien à attendre. Un premier twitt de Nicolas attire mon œil : « Mark Zuckerberg - 3 fois le mot semantic par phrase.. des graphs dans tous les sens avec des connections avec d'autres sites. hmm.. » Attiré, certes, mais sans grand espoir, je continue à vaquer à mes occupations numériques.
Facebook se met au Web sémantique ?
Open Graph Protocol
Facebook & Semantic Web
RDF Schema Follows
Following last week’s W3C Conference in Raleigh, Facebook and some semantic web leading lights, including W3C Semantic Web Activity Lead Ivan Herman, had a chance to make contact with each other. Facebook’s David Recordon got to explain the design decisions behind the Open Graph protocol, and in a breakout group with some of the semantic web folks – including Herman – they came up with a plan on how what Facebook is doing would be precisely described in terms of RDF schema. As Facebook reports on its developer blog, “members of the W3C’s Linked Data Camp helped to develop a RDF schema file which relates the Open Graph protocol to existing ontologies (such as Dublin Core, FOAF, and DBpedia).” Further, note this from the blog: “Beyond helping relate the Open Graph protocol to Semantic Web technologies and developing a variety of open source implementations, the community identified that a page type for an ‘article’ (such as a blog post or story on CNN) was missing.Facebook, with its open graph announcements at the f8 conference today , is digging itself deep into the infrastructure of the web. Outside developers and existing sites will now be able to hook into Facebook users’ data and activities directly and persistently, keeping logs well beyond the previous limit of 24 hours. Organizing the world’s information by powering it is clearly a direct affront to Google. Where Google observes links and relationships between web sites from a distance, Facebook aims to be the glue that connects the web itself . The implications are thrilling, but also scary — what if Facebook goes down? The benefits of using a Facebook authentication system were already strong.
Central Point of Failure ?
“Oh mon dieu, Facebook fait du web sémantique, mais c’est horrible !” se sont écriés à la fois le gros newbe du web et Alex Iskold, CEO de la startup très sémantique et bientôt disparu: GetGlue . Le gros newbe du web dit que c’est horrible car il pense que Facebook va l’espionner pour revendre ses informations aux chinois du FBI. Et Alex Iskold dit que c’est horrible car il vient de jeter un oeil au code de Facebook et c’est moins beau que ce qu’il a développé en 4 ans, avec $6 M .
et alors ?
N'importe quoi ...
W3C is pleased
At the Semantic Technology conference in San Francisco last week, I met up with two W3C representatives to discuss the current state of the Semantic Web - a Web of added meaning and structured data. W3C, the World Wide Web Consortium, is the official standards organization of the Web and is led by Sir Tim Berners-Lee. I spoke with W3C Semantic Web Activity Lead Ivan Herman and W3C eGovernment Interest Group leader Sandro Hawke.This week we've been exploring the emergence of the Semantic Web among companies like Best Buy and Google . It's all thanks to RDFa , code that is inserted into the HTML of web pages to add extra meaning. The increasing usage of RDFa was one of the main themes at the recent Semantic Technology conference in San Francisco. There is perhaps no better example than Facebook 's use of RDFa. We chatted to Facebook open standards evangelist David Recordon to find out more.
