This paper is about the relationship between the topic map and RDF standards families. It compares the two technologies and looks at ways to make it easier for users to live in a world where both technologies are used. This is done by looking at how to convert information back and forth between the two technologies, how to convert schema information, and how to do queries across both information representations. Ways to achieve all of these goals are presented. This paper extends and improves on earlier work on the same subject, described in [Garshol01b]. This paper was first published in the proceedings of XML Europe 2003, 5-8 May 2003, organized by IDEAlliance, London, UK.

The OpenLink Data Explorer is a browser extension (currently available for Firefox with additional browser support to follow) that adds a new option to the Web User Agent functionality realm in the form of new main and context menu options for viewing Data Sources associated with Web Pages.

The Open Data Movement aims at making data freely available to everyone. There are already various interesting open data sets availiable on the Web. Examples include Wikipedia, Wikibooks, Geonames, MusicBrainz, WordNet, the DBLP bibliography and many more which are published under Creative Commons or Talis licenses. The goal of the W3C SWEO Linking Open Data community project is to extend the Web with a data commons by publishing various open datasets as RDF on the Web and by setting RDF links between data items from different data sources. RDF links enable you to navigate from a data item within one data source to related data items within other sources using a Semantic Web browser. RDF links can also be followed by the crawlers of Semantic Web search engines, which may provide sophisticated search and query capabilities over crawled data. As query results are structured data and not just links to HTML pages, they can be used within other applications.

The Semantic Web, a knowledge-centric model for the Web's future, supplements human-readable documents and XML message formats with data that can be understood and processed by machines. SPARQL Protocol and RDF Query Language (SPARQL) is to the semantic Web as SQL is to a relational database. It allows applications to make sophisticated queries against distributed RDF databases, and is widely supported by many competing frameworks. This tutorial demonstrates its use through the example of a team tracking and journaling system for a virtual company.

ibm's rdf store. this was the project that was forked to create anzo.

Creativecommons' recommended metadata format - allows embedding of RDFa metadata info into any file - so tracking authorship, attribution and so on as well as media formats.
