SweoIG/TaskForces/CommunityProjects/LinkingOpenData - ESW Wiki News 2014-12-03: The 8th edition of the Linked Data on the Web workshop will take place at WWW2015 in Florence, Italy. The paper submission deadline for the workshop is 15 March, 2015. 2014-09-10: An updated version of the LOD Cloud diagram has been published. Project Description The Open Data Movement aims at making data freely available to everyone. The goal of the W3C SWEO Linking Open Data community project is to extend the Web with a data commons by publishing various open data sets as RDF on the Web and by setting RDF links between data items from different data sources. RDF links enable you to navigate from a data item within one data source to related data items within other sources using a Semantic Web browser. The figures below show the data sets that have been published and interlinked by the project so far. Clickable version of this diagram. Project Pages The project collects relevant material on several wiki pages. Meetings & Gatherings LOD Community Gatherings See Also Demos 1.
RDF - Semantic Web Standards Overview RDF is a standard model for data interchange on the Web. RDF has features that facilitate data merging even if the underlying schemas differ, and it specifically supports the evolution of schemas over time without requiring all the data consumers to be changed. RDF extends the linking structure of the Web to use URIs to name the relationship between things as well as the two ends of the link (this is usually referred to as a “triple”). Using this simple model, it allows structured and semi-structured data to be mixed, exposed, and shared across different applications. This linking structure forms a directed, labeled graph, where the edges represent the named link between two resources, represented by the graph nodes. Recommended Reading The RDF 1.1 specification consists of a suite of W3C Recommendations and Working Group Notes, published in 2014. A number of textbooks have been published on RDF and on Semantic Web in general. Discussions on a possible next version of RDF
OWL - Semantic Web Standards Overview The W3C Web Ontology Language (OWL) is a Semantic Web language designed to represent rich and complex knowledge about things, groups of things, and relations between things. OWL is a computational logic-based language such that knowledge expressed in OWL can be exploited by computer programs, e.g., to verify the consistency of that knowledge or to make implicit knowledge explicit. OWL documents, known as ontologies, can be published in the World Wide Web and may refer to or be referred from other OWL ontologies. The current version of OWL, also referred to as “OWL 2”, was developed by the [W3C OWL Working Group] (now closed) and published in 2009, with a Second Edition published in 2012. Recommended Reading These documents are, however, all rather technical and mainly aimed at OWL 2 implementers and tool developers. A number of textbooks have been published on OWL, and on Semantic Web in general. (Note that you can browse tools per tool categories or programming languages, too.)
Over a half million restaurants to choose from, but we'll h About rich snippets and structured data - Webmaster Tools Help Rich snippets (microdata, microformats, RDFa, and Data Highlighter) Snippets—the few lines of text that appear under every search result—are designed to give users a sense for what’s on the page and why it’s relevant to their query. If Google understands the content on your pages, we can create rich snippets—detailed information intended to help users with specific queries. For example, the snippet for a restaurant might show the average review and price range; the snippet for a recipe page might show the total preparation time, a photo, and the recipe’s review rating; and the snippet for a music album could list songs along with a link to play each song. These rich snippets help users recognize when your site is relevant to their search, and may result in more clicks to your pages. Three steps to rich snippets: 1. Google suggests using microdata, but any of the three formats below are acceptable. 2. Google supports rich snippets for these content types: 3. That’s it! Use HTML markup if...
OWL The OWL Web Ontology Language is designed for use by applications that need to process the content of information instead of just presenting information to humans. OWL facilitates greater machine interpretability of Web content than that supported by XML, RDF, and RDF Schema (RDF-S) by providing additional expressive power along with a formal semantics. The group's work is complete with the publication of OWL 2 (Second Edition). There may be new Errata and discussion on public-owl-dev@w3.org. Second Edition Deliverables See Documentation Roadmap for more details First Edition Deliverables Editors' Drafts (Wiki) Inputs Membership Charter, Meeting Records, and History The OWL Working Group Charter shows what the W3C has asked this working group to do.

FOAF-a-matic — Describase a si mismo en RDF Escrito por Leigh Dodds. Traducido por Leandro Mariano López. Introducción FOAF-a-matic es una simple aplicación de Javascript que le permite crear un descripción FOAF ("Friend-of-A-Friend" o Amigo-de-un-Amigo) de si mismo. Puede leer más (en inglés) acerca de FOAF en el articulo de Edd Dumbill "XML Watch: Finding friends with XML and RDF", en the FOAF homepage on RDFWeb, y tambien the FOAF vocabulary description. En castellano existe el documento "FOAF: el proyecto 'Friend-of-a-friend'", de Leandro Mariano López. Resumiendo, FOAF es una manera de describirse a uno mismo -- nombre, dirección de email, y la gente de quienes es amigo -- usando XML y RDF. FOAF-a-Matic le provee a usted una manera rápida y fácil de crear su propia descripción FOAF. Nota: nada de la información suministrada en esta página es usada o almacenada en ningún modo. Si tiene comentarios acerca de esta aplicación, u otras preguntas acerca de FOAF, por que no se une a la lista de correo RDFWeb-dev? Gente Que Conoce
Linked Data | Linked Data - Connect Distributed Data across the Web 9th Extended Semantic Web Conference (ESWC), Heraklion 2012 - VideoLectures The Extended Semantic Web Conference (ESWC) is a major venue for discussing the latest scientific results and technology innovations around semantic technologies. Building on its past success, ESWC is seeking to broaden its focus to span other relevant research areas in which Web semantics plays an important role. The goal of the Semantic Web is to create a Web of knowledge and services in which the semantics of content is made explicit and content is linked to both other content and services novel applications allowing to combine content from heterogeneous sites in unforeseen ways and support enhanced matching between users needs and content. This network of knowledge-based functionality will weave together a large network of human knowledge, and make this knowledge machine-processable to support intelligent behaviour by machines. Detailed information can be found at ESWC 2012 website.
