Scott Davis makes a case for metadata or semantic data, pointing out that it is currently used by major websites to improve their traffic or the rank of the pages searched. He is presenting the most common ways to add metadata to a document: RDFa and microformats.
Google, Microsoft and Yahoo! have decided to propose a common markup vocabulary, Schema.org, based on the Microdata format, simplifying the job of webmasters who want to give meaning to their web pages content.
A lack of mutually agreed-upon SOA terms, definitions and concepts can create interoperability issues that inhibit end-to-end business activities within an organization, as well as between vendor, customer, and partner organizations. A new Open Group Standard - Service-Oriented Architecture Ontology - is trying to fill this gap.
Nuxeo introduces fise - an open source RESTful semantic engine to which NUXEO has made contributions. The goal of the fise is to "help bring new and trendy semantic features to CMS by giving developers a stack of reusable HTTP semantic services to build upon." fise is part of a larger effort, IKS (Interactive Knowledge Stack) as a means of enhancing CMS offerings with Semantic Web capabilities.
The W3C Media Annotations Working Group has recently posted drafts of its Ontology for Media Resource 1.0 and API for Media Resource 1.0 efforts. They have also updated the Use Cases document to reflect some of the intentions of these projects. The basic goal of the Working Group is to produce an API and domain model for handling the explosion of media content on the Web.
The Web is known primarily as a Web of Documents because that has been our main experience with it, but we should not ignore the idea of documents as a data source. New technologies are emerging to make it easier to encode extractable content on the Web. This article focuses on how producers can increase the machine-processability of the documents they produce.
In this second article in the Resource-Oriented Architecture series, Brian Sletten discusses the benefits of REST, what constitutes a resource, associating metadata with a resource, the pitfalls of common models of resource metadata, SPARQL, RDF, expressing RDF facts, RDF triples, querying RDF, and sample RDF queries.
In this first article in the Resource-Oriented Architecture series, Brian Sletten discusses the REST architecture style, the history of SOA, SOAP and WS-*, the Semantic Web, URLs as identifiers, URIs and URNs, freedom of form, logically-connected late-binding systems, HATEOAS, and the impact of the Semantic Web upon software systems.
As the Dutch artist MC Escher once said "Only those who attempt the absurd will achieve the impossible". Hence we are trying to stretch the .NET framework to cover the Cloud such that it will become possible to incrementally and seamlessly design, develop, and debug complex distributed applications using your favorite existing and unmodified .NET compiler and deploy these applications anywhere.
In this interview from QCon San Francisco 2008, Stu Charlton discusses what the Semantic Web is, RDFa, large-scale adoption of Semantic Web, the SPARQL query language, implementing Semantic Web capabilities in an application, triple stores, and performing a Semantic Web query.
Top rubyist Rich Kilmer gives InfoQ visitors an eye-opening look into his years of success using Ruby to tackle tough defense-related challenges at Darpa. Our interview covers a wide range of cutting-edge technologies from DSLs to Semantic Web technologies such as OWL, to using Flash as a front-end UI framework.
