dave sgonechinaTwine uses RDF in its bookmarking. Good explanation of RDF and OWL, too.

Processing data in this clear 1, 2, 3 format is much faster and less error-prone than “screen scraping” the web page in the hope of retrieving the correct fields. Twine’s knowledge of Jurassic Park is simply the set of all tuples that have this book as the subject. When two tuples refer to the same object, they become linked and in this way start to build a semantic graph. In short, Twine uses tuples to access a tremendous breadth and depth of information about any given subject.
-
Another important aspect of RDF is that each object or resource, no matter its location on the Internet, is referred to by a universally distinct identifier or URI.
-
Twine uses another important technology called OWL (Web Ontology Language) to define these properties and classes, and to determine their uses.

Twine’s “smarts” are derived from the simplicity of three-part RDF statements, often called triples or tuples. In fact, all information in Twine— whether about a particular object, person, note, bookmark, tag, email message, or even a video—is expressed in a set of tuples.

As Tim Berners-Lee and others have described it, the Semantic Web creates a web of data that allows computers to find, extract, share, re-use information, and potentially even reason with it. Semantic content can be embedded in web pages, published from databases, and gathered into online repositories. Most important, semantic data itself contains “meta-information” so that other services are able to make sense of it. For example, the Semantic Web uses markup not only to indicate how something should be rendered, but also to express content (e.g. the authorship, title, and date of an article).

DF documents like the one above are made up of simple three-part statements in the form
. For example, a system will see that Jurassic Park * has an author: Michael Crichton * was released on: 9/07/2006 * and has a comment, made by /user/lew. Processing data in this clear 1, 2, 3 format is much faster and less error-prone than “screen scraping” the web page in the hope of retrieving the correct fields. Twine’s knowledge of Jurassic Park is simply the set of all tuples that have this book as the subject. When two tuples refer to the same object, they become linked and in this way start to build a semantic graph. In short, Twine uses tuples to access a tremendous breadth and depth of information about any given subject. Another important aspect of RDF is that each object or resource, no matter its location on the Internet, is referred to by a universally distinct identifier or URI. In the case above, the URI is: “http://www.twine.com/item/1sj51123-2g5”. This distinct identifier allows Twine to specify the book object and not confuse it with any other book object that might have the same title or author. A book might be collected by one or more users in the system, so it’s important to uniquely identify the book by its URI in order to know precisely what object is a favorite of a particular user. By building on the foundational technologies of the Semantic Web, specifically RDF, Twine hopes to provide its users with an open and extensive platform for organizing, sharing and discovering information. By making information accessible to a wider audience, Twine also seeks to foster the growth of the Semantic Web.
