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
In an attempt to reaching out to the Web developers (called 'Hacker Joe', here ;) I've compiled a screen-cast on how one can understand the Web as a huge database . The screen-cast starts out with a bit of explanation of some essentials, however, the bigger part of it is dedicated to two hands-on examples: first we query and use data from DBPedia (the linked data version of Wikipedia) and then we look into a heavily distributed linked data form, that is, using a FOAF profile we again query and use data from there. Note that the accompanying slides are available as well via slideshare . In case you want to test the queries used in the screen-cast along with the endpoints, here you are ...
Up to Design Issues The Semantic Web isn't just about putting data on the web. It is about making links, so that a person or machine can explore the web of data. With linked data, when you have some of it, you can find other, related, data. Like the web of hypertext, the web of data is constructed with documents on the web. However, unlike the web of hypertext, where links are relationships anchors in hypertext documents written in HTML , for data they links between arbitrary things described by RDF ,.
This book gives an overview of the principles of Linked Data as well as the Web of Data that has emerged through the application of these principles. The book discusses patterns for publishing Linked Data, describes deployed Linked Data applications and examines their architecture. The World Wide Web has enabled the creation of a global information space comprising linked documents. As the Web becomes ever more enmeshed with our daily lives, there is a growing desire for direct access to raw data not currently available on the Web or bound up in hypertext documents. Linked Data provides a publishing paradigm in which not only documents, but also data, can be a first class citizen of the Web, thereby enabling the extension of the Web with a global data space based on open standards - the Web of Data. In this Synthesis lecture we provide readers with a detailed technical introduction to Linked Data.
The objective of this SPARQL tutorial is to give a fast course in SPARQL. The tutorial covers the major features of the query language through examples but does not aim to be complete.
The Semantic Web is based on the relatively straightforward idea that to be able to integrate (link) data on the Web we must have some mechanism for knowing what relationships hold among the data, and how that relates to some “real world” context.
