Towards the semantic web: Easy RDF
Two new tools to take the future of the web a step closer Most of us have a rough idea by now that it all starts with having content published on websites using decent schemas.
For now, the semantic web relies on RDF, and that if content is published in RDF, then OWL can be easily mapped Simply put, RDF supports the 'syntax' of the content, OWL supports the semantics, as well as lots of other meaningful information about relationships, logic, axiom that will help us use the content to enable process automation. Or at least, to try. It's a start.
Right now RDF and OWL use 'triples, subject-predicate-object expressions In the future, we might step up our statements to 'quadruples', perhaps. In the meantime we take semantic statements at face value, in the absence of alternatives, but to have content into RDF is a skilled task, a specialized functionality How come we cant just produce RDF dynamically, in the same way that our systems produce RSS, or other types of feed?
Today, two new tools were announced. First a Firefox extension of Tabulator (alpha release) Based on code from the original Tabulator web application, the Tabulator Extension integrates the ability to browse linked data directly into Firefox. After installing the extension, pages served as application/rdf+xml and text/n3 will be automatically loaded into a Tabulator outline view for easy browsing, wish the developers A single store contains all of the data found during a Firefox session, smushing the data from all loaded documents together as you continue to browse.
Queries can then be generated across the entire store in the same way as the original Tabulator web application. James Hollenbach, from the Tabulator team says: "New in this version is the ability to directly edit files in real time through the outline interface. This feature is still largely in testing (it allows the user to enter values that should not be valid in many cases), but it is a very powerful interface for quickly editing RDF.
A testing environment for editing Here At Web2express, Aj Chen acknowledges that one of the big challenges facing semantic web is to encourage people to put out their data in semantic format on the web. "I have been looking into practical areas where semantic web can make real difference.
Datafeed is such an area, I believe." Aj just released a free new online tool - unified data feed on web2express.org to help people create data feeds for products, news, events, jobs and studies. Besides the feeds, all of the data are also openly available as RDF. The semantic web happens a small step at the time.
