Future Software Architectures Combining the Web 2.0 with the Semantic Web to realize future Web Communities Maarten Visser 30.11.2005 Topics    Current Web Standards Upcoming Web Standards The Future of the Web Communities Current Web standards    Web Data standards Web Service standards Web Client standards Current Web Data Standards  HTML – – Human readable web publications Used for webpages  XML (eXtensible Markup Language) – – Human readable tags to describe data Making data interoperable within a singe domain (schema)  RSS (Really Simple Syndication) / OPML – – Subscriptions to Human readable content XML file formats for Web syndication used by (amongst other things) news websites and weblogs RSS Publication Types Current Web Service Standaards Webservices: Machine-to-machine interaction over a network  SOAP – Protocol for exchanging XML-based messages over a network  WSDL (Web Services Description Language) – XML format for describing Web services  UDDI (Universal Description, Discovery, and Integration) – Platform-independent, XML-based registry for webservices  WS-* – – – WS-Security (Web Services Security protocol for authentication) WS-Reliability (SOAP-based specification for reliable messaging) WS-A lot more.. Current Web Client Standaards  Internet Browser – – – HTML Javascript Flash  “Feed readers” – – RSS aggregators Podcast clients  Apple Widgets / Microsoft Gadgets – Small standardized (Desktop) mini applications Companies But as with most new technologies This is only the beginning……. New Web Standard! SSE (Simple Sharing Extensions)    Ray Ozzie (Microsoft (ex Lotus)) Dave Winer (inventor RSS) Released under Creative Commons – – to use RSS as the basis for item sharing that is, the bi-directional, asynchronous replication of new and changed items amongst two or more cross-subscribed feeds to use OPML as the basis for outline sharing that is, the bi-directional, asynchronous replication of outlines, such as RSS aggregators subscription lists The Semantic Web     "The Semantic Web is an ... extension of the current web in which ... information is given well-defined meaning, ... better enabling computers and people to work in cooperation." The Semantic Web Tim Berners-Lee, James Hendler and Ora Lassila Scientific American, May 2001  Upcomming Web Standards The Semantic Web (Machine readable content: w3c)  RDF (Resource Description Framework) – – XML based standard for describing resources on the web Machine readable associations between subjects and objects  RDFS (RDF Schema) – Machine readable vocabularies that describe groups of related RDF resources and relationship between resources  OWL (Web Ontology Language) – a markup language for publishing and sharing data using machine readable ontology's on the Internet Upcomming Web Standards  SPARQL – Query language for RDF  FOAF (Friend of a Friend) – For creating a Web of machine-readable homepages describing people, there interests, there friends and more. The Current Web The Semantic Web The Future  The three layered internet architecture of the future could look like this… The future for Web Communities       People around the world working on similar project can be clustered as a group automatically Applications can automatically point you to people with similar interest Applications can automatically help you get the information you need Unlimited Interfaces to consume and respond to information Be in the middle of the world wide information flow… Real-time brainstorming with thousands of people.. The Challanges      Connecting and adding resources to all data Agreement on new standards Agreement on Universal Tag directories (Ontology's / Topic Maps) (Meta) Data may not be deleted Security and Privacy (who owns the data) – We need a “Google Like” Data Farm managed by a trusted world wide organisation The Future…  All people, processes and information is connected and machine readable…. Questions?
