linked semantic web data

I just arrived at O'Reilly's Sebastopol Campus where they're holding a *Camp event on the open web, eponymously named "Open Web Foo Camp". A few days ago I was speaking with Jim Dwyer of the New York Times about the Federated Indie Social Web vs. sharecropping and site death (more on that in another post), and he happened to ask me (probably because I mentioned it in passing), what is, or what do I mean by "the open web". At the time I didn't have a working definition, but apparently provided an answer good enough for a self-described non-technical journalist to "get" what is the open web.
Steffen asked me if I could also provide a few examples on how to actually put RDF triples in the HTML, as the template I gave yesterday is a mere empty canvas to draw the triples on. There are actually various examples in my blog, which I will summarize here. Before I start, I like to put some emphasize on the following RDFa pattern. An RDF resource that serves as subject is always mapped to a HTML element.

Similar to outside efforts like Microformats, HTML5′s microdata offers a way of extend HTML by adding custom vocabularies to your pages. The easiest way to understand it is to consider a common use case.
Written by Brian Cray on September 8th, 2010 Many big web design blogs are raving about HTML5, as they should be. But if you read many of them, [ 1 , 2 , 3 ], you'll be bombarded with an over-publicizing of header , article , footer , et. al tags, which reminds me of circa 2002 when we were all jumping onto the XHTML bandwagon. But 8 years later where'd XHTML get us? Suddenly we're moving back to HTML.

[ contents ] Abstract This document is a specification for a vocabulary to represent content in the Resource Description Framework ( RDF ). This vocabulary is intended to provide a flexible framework within different usage scenarios to semantically represent any type of content, be it on the Web or in local storage media. For example, it can be used by web quality assurance tools such as web accessibility evaluation tools to record a representation of the assessed web content, including text, images, or other types of formats.

I’ve invented a new Batman villain. His name is “The Modeller” and his scheme is to model Gotham city entirely accurately in a way that is of no practical value to anybody. He has an OWL which sits on his shoulder which has the power to absorb huge amounts of time and energy. The Modeller In the first issue, “ Batman vs the Modeller” the modeller gets away by confusing batman as to exactly which incarnation he currently is (Frank Miller, Golden age or Batman Begins) which forces Batman into an identity crisis where he registers different URIs and FOAF profiles for Batman and Bruce Wayne .
Edit : fise is now known as the Stanbol Enhancer component of the Apache Stanbol incubating project. As a member of the IKS european project Nuxeo contributes to the development of an Open Source software project named fise whose goal is to help bring new and trendy semantic features to CMS by giving developers a stack of reusable HTTP semantic services to build upon. As such concepts might be new to some readers, the first part of this blog post is presented as a Q&A. What is a Semantic Engine? A semantic engine is a software component that extracts the meaning of a electronic document to organize it as partially structured knowledge and not just as a piece of unstructured text content.
A misleading title perhaps, since WebGL isn’t generally available to iOS platform developers. Hacks aside, if you’re learning WebGL and have an iPhone it is still a very educational environment. WebGL essentially wraps OpenGL ES in a modern Web browser environment. You can feed data in and out as textures associated with browser canvas areas, manipulating data objects either per-vertex or per-pixel by writing ‘vertex’ and ‘fragment’ shaders in the GLSL language.
Overview Technology experts and stakeholders who participated in a recent survey believe online information will continue to be organized and made accessible in smarter and more useful ways in coming years, but there is stark dispute about whether the improvements will match the visionary ideals of those who are working to build the semantic web.

While HTML 5 has a bunch of semantic elements, including new ones like <article> and <nav> , sometimes there just isn’t an element with the right meaning. What we want are ways to extend what we’ve got, to add extra semantics that are machine-readable — data that a browser, script, or robot can use. Native ways to extend HTML There were five fundamental ways we could extend HTML 4: <meta> element class attribute rel attribute rev attribute profile attribute In HTML 5, rev has fallen by the wayside, becoming obsolete since hardly anyone used it correctly, and because it can be replaced by rel . profile is also obsolete, and there is no support for namespaces in HTML 5.
At the SemTech conference earlier this summer there was a kind of vuvuzela -like buzzing in the background. And, like the World Cup games on television, in play at the same time as the conference, I found the droning to be just as irritating. That droning was a combination of the sense of righteousness in the superiority of linked data matched with a reprise of the “ chicken-and-egg ” argument that plagued the early years of semantic Web advocacy  .
SKOS is an area of work developing specifications and standards to support the use of knowledge organization systems (KOS) such as thesauri, classification schemes, subject heading lists and taxonomies within the framework of the Semantic Web ... [ read more ] Alignment between SKOS and new ISO 25964 thesaurus standard (2012-12-13) ISO 25964-1, published in 2011, replaced the previous thesaurus standards ISO 2788 and ISO 5964 (both now withdrawn).
