JenaProposal. Nov 2010: This proposal has been accepted: Results email. Abstract Jena is a semantic web framework for Java, based on W3C standards. Proposal Jena provides a semantic web framework in Java that implements the key W3C recommendations for the core semantic web technologies of RDF and SPARQL. Jena is a number of components and modules built on this core system. It currently includes: an API for working with RDF Parsers and writers for the RDF formats (RDF/XML, Turtle, N-triples, NQuads, TriG) an implementation of SPARQL, the W3C standard RDF query language multiple storage systems for RDF data including in-memory, file-backed, in SQL databases and in custom scalable storage systems an API for manipulation of OWL a rule-based inference engine an implementation of GRDDL for extraction of RDF from XML formats a standards compliant IRI library.
This proposal includes the main components of Jena: the main Jena download, ARQ, GRDDL, SDB, TDB, the IRI library and Joseki. Background Rationale Alignment. WTF Is The Semantic Web? (Infographic) The WHATWG Blog » microdata. This Week in HTML5 – Episode 38 Welcome back to "This Week in HTML 5," where I'll try to summarize the major activity in the ongoing standards process in the WHATWG and W3C HTML Working Group. This week, there were some more refinements to microdata. r4139 changes the names of the DOM properties that reflect microdata markup. r4140 renames the content property to itemValue Since no browser has actually implemented this API yet, these changes shouldn't make any difference.
Standards are like sex; one mistake, and you're stuck supporting it forever! r4141 and r4147 fix up some microdata examples, in particular this example from Gavin Carothers about marking up O'Reilly's book catalog. Hooray for real-world examples! Other noteworthy changes this week: r4097 defines fallback content for the obsolete <applet> element.r4098 "dramatically simplifies <script defer> and <script async> handling. " Around the web: Tune in next week for another exciting edition of "This Week in HTML5. " Microdata. HTML Microdata. Dumb eBooks Must Die, Smart eBooks Must Live « The eBook Test. In a prior post, I withdrew my support for all eInk devices as being detrimental to the development of eBooks. Let me go further and repeat what I have been stating on Twitter: It is so. All eBooks — so-called — are right now nothing more than a lightly tarted-up text dump into a specific electronic container.
They’re objects with less capability than print (go on, riffle through those pages with eInk’s refresh rate!) And even dumber than print (uh, which page are you actually on?). They are unworthy of serious consideration. Here are two bits I’ve cloned from the blog of writer Warren Ellis: When I showed this tiny, heavy thing [an original Sony Walkman cassette tape player] to Lili [his young daughter], I’m wondering now if she was thinking, “yeah, it plays music, but what else does it do?” And: As a coda to the previous post, Jamais Cascio notes how the touchscreen generation interacts with a Kindle: They try to “turn the page” by flicking a finger across the screen. Jesus wept. And J.K. Introduction to Semantic Web (Part 2)
In the first part i talked about the characteristics on which the Semantic Web is built. Now I'll introduce a couple of standards tools that support those characteristics. The Standards and Tools i’ll cover are: RDFSparqlRDFa RDF (Resource Description Framewor): Is the De facto standard way of representing graph data for Semantic Werb, in a way that is both understandable by humans and machines.
Is a language in which evrything is represented as a Resource (or a literal value), the subject, the predicate and the object. Cc=" dc=" fb=" rdf=" xhtml=" about=" <fb:m.04l1354> <dc:description>The Other Side of Midnight is a novel ..... In this RDF we can see the three parts of every triple. In this case subject, predicate and object are all resources.
