Although the Semantic Web (SW) is still very much in its infancy, there is already a lot of data out there which conforms to the proposed SW standards (e.g. RDF and OWL). Small vertical vocabularies and ontologies have emerged, and the community of people using these is growing daily. People publish descriptions about themselves using FOAF (Friend of a Friend), news providers publish newsfeeds in RSS (RDF Site Summary), and pictures are being annotated using various RDF vocabularies. The amount of available formal data is growing steadily, but a means to find and thus utilize this data is still missing. What is needed is the equivalent of the services a search engine currently provides for the HTML-web: a service which continuously explores and indexes the Semantic Web and provides an easy-to-use interface through which users can find the data they are looking for.

The Tabulator project is a generic data browser and editor. Using outline and table modes, it provides a way to browse RDF data on the web. RDF is the standard for inter-application data exchange. You can use it in two ways As a Firefox Add-on The tabulator extension is a Firefox extension which allows Firefox to handle data as well as documents.

LinkedGeoData is an effort to add a spatial dimension to the Web of Data / Semantic Web. LinkedGeoData uses the information collected by the OpenStreetMap project and makes it available as an RDF knowledge base according to the Linked Data principles. It interlinks this data with other knowledge bases in the Linking Open Data initiative.

Knowledge bases are playing an increasingly important role in enhancing the intelligence of Web and enterprise search and in supporting information integration. Today, most knowledge bases cover only specific domains, are created by relatively small groups of knowledge engineers, and are very cost intensive to keep up-to-date as domains change. At the same time, Wikipedia has grown into one of the central knowledge sources of mankind, maintained by thousands of contributors. The DBpedia project leverages this gigantic source of knowledge by extracting structured information from Wikipedia and by making this information accessible on the Web under the terms of the Creative Commons Attribution-ShareAlike 3.0 License and the GNU Free Documentation License .
