W3 c semantic web activity

  1. 1. W3C Semantic Web ActivityThe Semantic Web provides a common framework that allows data to be shared andreused across application, enterprise, and community boundaries. It is a collaborativeeffort led by W3C with participation from a large number of researchers and industrialpartners. It is based on the Resource Description Framework (RDF). See also theseparate FAQ for further information.Further linksOn this page: Specifications | Publications | Presentations | Current Groups | PastGroupsLatest news: See the activity weblogLatest “layercake” diagram: in SVG, PNG, and small sized (300×315) PNG formats.Active Groups: Semantic Web Coordination Group | Rules Interchange FormatWorking Group | OWL Working Group | RDB2RDF Working Group | SPARQLWorking Group | Semantic Web Deployment Working Group | POWDER WorkingGroup | Health Care and Life Sciences Interest Group | Semantic Web Interest GroupPast Groups: Best Practices and Deployment Working Group | RDF Core WorkingGroup | Web Ontology Working Group | Education and Outreach Interest Group |GRDDL Working GroupRelated Groups at W3C: Semantic Sensor Network Incubator Group | Social WebIncubator Group | Linking Open Data Community Project | Media Fragments WorkingGroup | Media Annotations Working GroupNearby: SW FAQ | Use Cases and Case Studies | “Business Case for the SemanticWeb” | RDFa info page | List of Tools | On-line validators | List of Books | ActivityNews | Semantic Web Logos and ButtonsActivity RSS feeds: Activity news | W3C QA blog | FAQ | SW Use Cases and CaseStudiesIntroductionThe Semantic Web is a web of data. There is lots of data we all use every day, and it isnot part of the web. I can see my bank statements on the web, and my photographs, andI can see my appointments in a calendar. But can I see my photos in a calendar to seewhat I was doing when I took them? Can I see bank statement lines in a calendar?Why not? Because we dont have a web of data. Because data is controlled byapplications, and each application keeps it to itself.The Semantic Web is about two things. It is about common formats for integration andcombination of data drawn from diverse sources, where on the original Web mainlyconcentrated on the interchange of documents. It is also about language for recordinghow the data relates to real world objects. That allows a person, or a machine, to startoff in one database, and then move through an unending set of databases which areconnected not by wires but by being about the same thing.Specifications (Recommendations and Notes)You may want to look at the collection of SW Case Studies and Use Cases to see howorganizations are using these technologies today. The list of specifications is on aseparate page for a better readability.

The talk is also available on video.GroupsThe following groups are part of the Semantic Web Activity.Active GroupsSemantic Web Coordination GroupThe Semantic Web Coordination Group is tasked to provide a forum for managing theinterrelationships and interdependencies among groups focusing on standards andtechnologies that relate to this goals of the Semantic Web Activity. This group isdesigned to coordinate, facilitate and (where possible) help shape the efforts of otherrelated groups to avoid duplication of effort and fragmentation of the Semantic Web byway of incompatible standards and technologies.Rules Interchange Format Working GroupThis Working Group is chartered to produce a core rule language plus extensions whichtogether allow rules to be translated between rule languages and thus transferredbetween rule systems. The Working Group will have to balance the needs of acommunity diverse including Business Rules and Semantic users Web specifyingextensions for which it can articulate a consensus design and which are sufficientlymotivated by use cases.OWL Working GroupThe mission of the OWL Working Group, is to produce a W3C Recommendation thatrefines and extends the 2004 version of OWL. The proposed extensions are a small setthat: have been identified by users as widely needed, and have been identified by toolimplementers as reasonable and feasible extensions to current tools.RDB2RDF Working GroupThe mission of the RDB2RDF Working Group, part of the Semantic Web Activity, is tostandardize a language for mapping relational data and relational database schemas intoRDF and OWL, tentatively called the RDB2RDF Mapping Language, R2RML.SPARQL Working GroupFormerly known as RDF Data Access Working Group, it developed the SPARQL QueryLanguage recommendation published in January 2008. The group is currently charteredto make small updates to the SPARQL specification that have been identified as usersand implementers as feasible and useful extensions.Semantic Web Deployment Working GroupThe mission of this Working Group is to provide guidance in the form of W3CTechnical Reports on issues of practical RDF development and deployment practices inthe areas of publishing vocabularies, OWL usage, and integrating RDF with HTMLdocuments.This group is also responsible for the development of the RDFa and SKOSspecifications.Semantic Web Interest GroupThe Semantic Web Interest Group is a forum for W3C Members and non-Members todiscuss innovative applications of the Semantic Web. The Interest Group also initiatesdiscussion on potential future work items related to enabling technologies that supportthe Semantic Web, and the relationship of that work to other activities of W3C and tothe broader social and legal context in which the Web is situated.Semantic Web Health Care and Life Sciences Interest Group
  4. 4. The Semantic Web Health Care and Life Sciences Interest Group is designed to improvecollaboration, research and development, and innovation adoption in the health care andlife science industries. Aiding decision-making in clinical research, Semantic Webtechnologies will bridge many forms of biological and medical information acrossinstitutions.Past GroupsRDF Core Working GroupThe RDF Core Working Group was chartered to consider update to the RDF Model andSyntax Recommendation, and to a few revisions to the RDF Schema specification.Web Ontology Working GroupThe Web Ontology Working Group was chartered to build upon the RDF Core work alanguage for defining structured web based ontologies which will provide richerintegration and interoperability of data among descriptive communities.Semantic Web Best Practices and Deployment Working GroupThe focus of the Semantic Web Best Practices and Deployment Working Group was toprovide hands-on support for developers of Semantic Web applications.Semantic Web Education and Outreach Interest GroupThe Semantic Web Education and Outreach Interest Group (SWEO) was chartered tocollect proof-of-concept business cases, demonstration prototypes, etc, based onsuccessful implementations of Semantic Web technologies, collect user experiences,develop and facilitate community outreach strategies, training and educationalresources.Gleaning Resource Descriptions from Dialects of Languages Working GroupThe mission of this Working Group was to complement the concrete RDF/XML syntaxwith a mechanism to relate other XML syntaxes (especially XHTML dialects or“microformats”) to the RDF abstract syntax via transformations identified by URIs.W3C staff assigned to the W3C Semantic Web Activity are: Harry Halpin, SandroHawke (see also private blog), Ivan Herman (see also private blog), EricPrud’hommeaux, Dave Raggett (see also private blog), and Ralph SwickIvan Herman, (W3C) Semantic Web Activity Lead, <ivan@w3.org> 2009-10-16$Id: Overview.html,v 1.432 2009/10/16 16:02:32 ivan Exp $Copyright © 1994-2009 W3C ® (MIT, ERCIM, Keio), All Rights Reserved.
