linked semantic web data
Get flash to fully experience Pearltrees
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.

Linked Data Patterns
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.

Microdata: HTML5âs Best-Kept Secret | Webmonkey | Wired.com
Given the amount of industry noise about native video and scripted animations, you’d be forgiven if you had never heard of the new microdata specification included in HTML5. 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. Let’s say you want list details about a business on your page — the name, address, telephone number and so on.
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. Why?

FISE - Enhancement Engines
Stateless REST analysis This stateless interface allows the caller to submit content to the Stanbol enhancer engines and get the resulting enhancements formatted as RDF at once without storing anything on the server-side. The content to analyze should be sent in a POST request with the mimetype specified in the Content-type header. The response will hold the RDF enhancement serialized in the format specified in the Accept header: curl -X POST -H "Accept: text/turtle" -H "Content-type: text/plain" \ --data "John Smith was born in London." http://fise.demo.nuxeo.com/engines By default the URI of the content item being enhanced is a local, non de-referencable URI automatically built out of a hash digest of the binary content.
Please read this carefully: Specification is undergoing changes. The Annotation Ontology specification is currently used as input for the activities of the W3C Open Annotation Community Group that works towards a common, RDF-based, specification for annotating digital resources. The Group effort starts by working towards a reconciliation of two proposals that have emerged over the past two years: the Annotation Ontology and the Open Annotation Model . Initially, editors of these proposals will closely collaborate to devise a common draft specification that addresses requirements and use cases that were identified in the course of their respective efforts.

Representing Content in RDF 1.0
[ contents ] 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. In many cases, it can be used together with HTTP Vocabulary in RDF 1.0 , which allows quality assurance tools to record the HTTP headers that have been exchanged between a client and a server.

For some time, we at the Open Knowledge Foundation have been working on a project to allow you to annotate the web. All of it. We’re now happy to announce two major releases: of Annotator, the code that makes web annotation possible, and AnnotateIt, a web service providing storage for your annotations. What are you [...]

Southampton ECS Web Team › The Modeller
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 ModellerChristophe Guéret's work on enhancing the Sugar platform with semantic technologies is full of promises for One Laptop Per Child project: it will allow many children around the World to publish and consume Linked Data. This fits with OLPC's and Sugar views on learning together by sharing knowledge, and LATC is paving the way for new perspectives in this area.

Semantic Copyright
Semantic Copyright is a platform for research and promotion of semantic technology solutions applied to the field of Intellectual Property Rights. Works protected by intellectual property rights, whether text, images, music files, audiovisuals, computer software, etc. are available, shared and disseminated by digital networks on a daily basis. These facts place the works into a risk of being exploited illegally or without following the wishes of the author or rightholder. This current situation of IPR holders requires effective technological solutions for the information and management of those rights in the digital environment. In addition, users also need tools that provide security and trust at the time they use such content in a lawful manner.Introducing fise, the Open Source RESTful Semantic Engine, Nuxeo Developers Blog
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. 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.Semantic Web
