Resource Description Framework (RDF) is a W3C standard data structure for storing arbitrary data on the web and elsewhere.[ 1 ] Its key advantages include flexibility in describing different kinds of data, ease of aggregation, and the availability of standards supported by both commercial and open source software. Several syntaxes are available for representing RDF data. RDF/XML was one of the earliest, and its frequent ugliness and syntactic complexity for representing what became little-used RDF features gave RDF a bad reputation in its early days, but RDF/XML doesn't have to be ugly.[ 2 ] Formats more popular today include n3, its sibling Turtle, N-triples, and RDFa (formerly "RDF/a"[ 24 ]).

Many research and evaluation projects in the few years of the Semantic Web technologies produced ontologies, and significant data stores, but the data, if available at all, is buried in a zip archive somewhere, rather than being accessible on the web as linked data. The Biopax project, the CSAktive data on computer science research people and projects were two examples. [The CSAktive data is now (2007) available as linked data] There is also a large and increasing amount of URI s of non-ontology data which can be looked up. Semantic wikis are one example. The "Friend of a friend" ( FOAF ) and Description of a Project ( DOAP ) ontologies are used to build social networks across the web. http://www.w3.org/DesignIssues/LinkedData.html Linked Data - Design Issues

Minding the Planet: What's After the Real Time Web? Decentralization . As the semantics of the Web get richer, and the WebOS really emerges it will finally be possible for applications to leverage federated, Web-scale computing. This is when intelligent agents will actually emerge and be practical. By this time the Web will be far too vast and complex and rapidly changing for any centralized system to index and search it. Only massively federated swarms of intelligent agents, or extremely dynamic distributed computing tools, that can spread around the Web as they work, will be able to keep up with the Web. http://novaspivack.typepad.com/nova_spivacks_weblog/2009/10/whats-after-the-real-time-web.html

Quels sont les futurs possibles du web ? by miniseb Dec 13

http://techcrunch.com/2010/01/22/t2-bing-google-radar-semantic-search-race/ But both are facing a buy-or-build decision when it comes to semantic search. Bing’s recipe search is only based on partner feeds and tags, not a proper semantic index. Radar Networks is a serious player here, with a total of $24 million in capital raised since 2006. It owns four patents on the technology, with 20 more pending. Radar is essentially building a huge structured database for every page on the Web, which breaks down the information contained on those pages into well-defined facets.

Beyond Twitter Search: Semantic Analysis of the Real-Time Web http://www.readwriteweb.com/archives/beyond_twitter_semantic_analysis_of_the_real-time_web.php And let's not forget the main dish - the live-updating stream of tweets. The message stream shows who tweeted what, when and what Twitter client they used to do so, which is the same information you would see on Twitter.com. However, where Twitter's own homepage and search results pages stay put until you refresh them, this message stream moves in real-time as tweets come in. If it goes too fast for you (something that's a real possibility when you watch a currently hot trend), you can pause the stream with a click of a button. For data hounds, search results like these are tantalizing to say the least. And this engine is now just one of many that has access to Twitter's entire stream of tweets.
