Resource Description Framework The Resource Description Framework (RDF) is a family of World Wide Web Consortium (W3C) specifications [1] originally designed as a metadata data model. It has come to be used as a general method for conceptual description or modeling of information that is implemented in web resources, using a variety of syntax notations and data serialization formats. Overview[edit] Resource Description Framework
Faceted navigation for document discovery Faceted navigation for document discovery Better search with faceted navigation Text search is one of the most important ways that users of enterprise content can find the documents they need. Unfortunately, there are a number of reasons why enterprise text search systems often work less well than search of the public Internet (Enterprise Search: Tough Stuff, Rajat Mukherjee and Jianchang Mao. ACM Queue vol. 2, no. 2, April 2004).
The Resource Description Framework (RDF) is a language for representing information about resources in the World Wide Web. This Primer is designed to provide the reader with the basic knowledge required to effectively use RDF. It introduces the basic concepts of RDF and describes its XML syntax. It describes how to define RDF vocabularies using the RDF Vocabulary Description Language, and gives an overview of some deployed RDF applications. It also describes the content and purpose of other RDF specification documents. RDF Primer RDF Primer
SPARQL SPARQL SPARQL (pronounced "sparkle", a recursive acronym for SPARQL Protocol and RDF Query Language) is an RDF query language, that is, a query language for databases, able to retrieve and manipulate data stored in Resource Description Framework format.[1][2] It was made a standard by the RDF Data Access Working Group (DAWG) of the World Wide Web Consortium, and is recognized as one of the key technologies of the semantic web. On 15 January 2008, SPARQL 1.0 became an official W3C Recommendation,[3][4] and SPARQL 1.1 in March, 2013.[5] SPARQL allows for a query to consist of triple patterns, conjunctions, disjunctions, and optional patterns.[6] Implementations for multiple programming languages exist.[7] "SPARQL will make a huge difference" making the web machine-readable according to Sir Tim Berners-Lee in a May 2006 interview.[8]
ar·got·ic (ahr-got-ik) A specialized idiomatic vocabulary peculiar to a particular class or group of people.One of the most powerful and extensible web content syndication frameworks available to .NET developers.Project DescriptionA powerful and extensible .NET web content syndication framework for RSS, Atom, OPML, APML, BlogML, RSD and more. The Argotic Syndication Framework is a Microsoft .NET class library framework that enables developers to easily consume and/or generate syndicated content from within their own applications. The framework makes the reading and writing syndicated content in common formats such as RSS, Atom, OPML, APML, BlogML, and RSD very easy while still remaining extensible enough to support common/custom extensions to the syndication publishing formats.

The Matchmaker is also a web service that helps make connections between service requesters and service providers. The Matchmaker serves as a "yellow pages" of service capabilities. The Matchmaker allows users and/or software agents to find each other by providing a mechanism for registering service capabilities. Registration information is stored as advertisements. When the Matchmaker agent receives a query from a user or another software agent, it searches its dynamic database of advertisements for agents that can fulfill the incoming request.

LibraryThing LibraryThing LT members who’ve been around for a year or so may remember our partnership with Books Matter, an organization dedicated to providing books to needy schools in Ghana. I caught up with Keith Goddard—founder of Books Matter—this week, who was kind enough to update me on their latest projects! Interested in donating to Books Matter? Drop me a line at loranne@librarything.com to donate books, or visit their website for monetary donations. Can you tell us a bit about how Books Matter got started? Basically, three things happened.
Update February 2011: This has been translated into Dutch: Hoe maak je een facetclassificatie en hoe plaats je haar op het web? Many thanks to Janette Shew and the Information Architecture Institute's Translations Initiative for doing this. Also, How to Reuse a Faceted Classification and Put It On the Semantic Web, by Bene Rodriguez-Castro, Hugh Glaser and Les Carr, takes my example of dishwashing detergents and extends it into ontologies and RDF. Update February 2007: IA Voice has used this paper as the basis for a series of four podcast episodes!
