Specification | UDDI The current list of specifications advanced by the OASIS UDDI Specification Technical Committee includes: The UDDI Version 2 specifications, UDDI Version 3 specification and the Schema Centric XML Canonicalization Specification represent contributed material. Notes and Disclaimers are provided on each of these specification documents. UDDI Version History Since UDDI was proposed in 2000, it has evolved to reflect the need for manageability and federated control in enterprise operating scenarios, as well as to integrate more fully with other elements of service-oriented infrastructure. Version 1.0, released in 2000, created a foundation for the registry of Internet-based business services. UDDI Version 3 Specification The UDDI v3 OASIS Standard builds on the vision of UDDI as a "meta service" for locating Web services by enabling robust queries against rich metadata. UDDI Version 2 Specifications The UDDI v2 OASIS Standard set of specifications consists of the following documents:

Web Ontology Language Istnieją trzy odmiany języka OWL: OWL Lite;OWL DL (rozszerzenie OWL Lite);OWL Full (rozszerzenie OWL DL). OWL został uznany w lutym 2004 roku za standard przez W3C. RDF i OWL są bardzo podobne i dotyczą tego samego problemu, jednak OWL jest językiem bardziej rozbudowanym, z większym słownikiem i mocniejszą składnią.

Aunque toma su nombre por analogía, ésta es la diferencia con el punto de vista filosófico de la palabra ontología. Un uso común tecnológico actual del concepto de ontología, en este sentido semántico, lo encontramos en la inteligencia artificial y la representación del conocimiento. En algunas aplicaciones, se combinan varios esquemas en una estructura de facto completa de datos, que contiene todas las entidades relevantes y sus relaciones dentro del dominio. Típicamente, las ontologías en las computadoras se relacionan estrechamente con vocabularios fijos –una ontología fundacional– con cuyos términos debe ser descrito todo lo demás.

Resource Description Framework Przykład opisu w modelu RDF. RDF (ang. Resource Description Framework) - język/metoda pozwalająca na opisywanie zasobów sieci Web, ze składnią opartą na XML, opracowana przez W3C. Służy przedstawieniu (nie zaś wyświetlaniu) wiedzy zawartej w Internecie, w sposób zrozumiały dla komputerów (łatwo przetwarzany przez programy komputerowe). RDF jest odpowiedzią na problem niezliczonej ilości danych: dokumentów tekstowych, zdjęć, grafik, filmów wideo, plików dźwiękowych, nad którymi trudno zapanować, zarządzać czy w jakikolwiek sposób sklasyfikować. Celem RDF jest utworzenie ogólnoświatowego standardu zapisu metadanych (danych o danych), w którym nie byłoby miejsca na dowolność taką jak w znacznikach <meta>. Założeniem RDF jest opis zasobu za pomocą wyrażenia składającego się z trzech elementów: podmiotu, orzeczenia/predykatu (własność) i dopełnienia/obiektu (wartość). <? jest zasobem,element <autor> jest własnością,zaś Jan Kowalski jest wartością.

Jena - Welcome to Jena Linked data An introductory overview of Linked Open Data in the context of cultural institutions. In computing, linked data (often capitalized as Linked Data) describes a method of publishing structured data so that it can be interlinked and become more useful. It builds upon standard Web technologies such as HTTP, RDF and URIs, but rather than using them to serve web pages for human readers, it extends them to share information in a way that can be read automatically by computers. This enables data from different sources to be connected and queried.[1] Tim Berners-Lee, director of the World Wide Web Consortium, coined the term in a design note discussing issues around the Semantic Web project.[2] Principles[edit] Tim Berners-Lee outlined four principles of linked data in his Design Issues: Linked Data note,[2] paraphrased along the following lines: All kinds of conceptual things, they have names now that start with HTTP.I get important information back.

About WordNet - WordNet - About WordNet RDF/OWL Representation of WordNet Abstract This document presents a standard conversion of Princeton WordNet to RDF/OWL. It describes how it was converted and gives examples of how it may be queried for use in Semantic Web applications. Status of this Document This section describes the status of this document at the time of its publication. This document is a First Public Working Draft produced by the Semantic Web Best Practices and Deployment Working Group, part of the W3C Semantic Web Activity. Comments on this document are encouraged and may be sent to public-swbp-wg@w3.org; please include the text "comment" in the subject line. At the time of publication the charter of the Semantic Web Best Practices and Deployment Working Group is expiring and no chartered group has been proposed to continue further work on this document. The URIs specified in this document for WordNet terms are served by W3C in accordance with its resource persistence policy. Acknowledgements Table of Contents 1. 2.

RDF Primer The Resource Description Framework (RDF) is a language for representing information about resources in the World Wide Web. This Primer is designed to provide the reader with the basic knowledge required to effectively use RDF. It introduces the basic concepts of RDF and describes its XML syntax. It describes how to define RDF vocabularies using the RDF Vocabulary Description Language, and gives an overview of some deployed RDF applications. 1. The Resource Description Framework (RDF) is a language for representing information about resources in the World Wide Web. RDF is intended for situations in which this information needs to be processed by applications, rather than being only displayed to people. RDF is based on the idea of identifying things using Web identifiers (called Uniform Resource Identifiers, or URIs), and describing resources in terms of simple properties and property values. Figure 1 illustrates that RDF uses URIs to identify: <? What does RDF look like? 2. (URL).
