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

• But as with most new technologies
• This is only the beginning.

11
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

12
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

13
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 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..

21
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

22
The Future

• All people, processes and information is
  connected and machine readable.
