Concern Semantic Web XMLAdvantages
Disadvantages of XML
  • Everyone lauds XML its the foundation of
    semantic web and mother of all to happen.
  • Advantages are awesome.
  • Disadvantages
  • Hardly any one discusses this subject. Throw
    disadvantages of XML at Google. Then, try
    advantages of XML and see!
  • See Weaknesses of XML in a DevGuru tutorial
    (circa 2000?) or WDVL Tutorial (circa 1999)
    reasons are no longer valid, except for
    verbosity complaint.
  • Summary critic of XML.
  • If not XML, what else could we use? Keep in mind
    the principle of separation of data and rendering
    apart. SGML?!!!!!! Graphics???
  • XML also being infused more and more into other
    technologies.
  • See Next slide.

Concern Semantic Web XMLNative XML support in
ECMAScript?
  • ECMAScript aka Javascript.
  • Provides client side XML processing.
  • In your opinion
  • Is it worth the effort?
  • Future senario? Why not semantic client?
  • Other issues?
  • See Initiative for new the ECMAScript Standard
    E4X.
  • See ECMA for other standards, such as C, .NET
    F/W
  • Ajax support for XML?
  • Ajax supplies clean XML support allowing full XML
    documents to be streamed to the client for rich
    messages which are easy to process via standard
    JavaScript DOM support Ref ActiveMQ.
  • As we said in our Enterprise AJAX overview, AJAX
    is a recent term (early 2005) for leveraging the
    communication, XML, and CSS capabilities of
    modern browsers via JavaScript . Ref TIBET

5
XML in Semantic web?
  • XML and the Semantic web in Cover Pages.
  • Tim Berners-Lee Building the Future slide.
  • gt XML is at the foundation of Semantic web.

XML Extensions MLs
  • CML (ChemML), MathML, MusicML, GraphML, ...
  • ebXML
  • Multimedia extension MPEG 7

Multimedia Semantics
  • SAMT 2008 - CALL FOR PARTICIPATION
  • 3rd International Conference on Semantic And
    digital Media Technologies, Koblenz, Germany, 3-5
    December 2008
  • the semantics and pragmatics of multimedia
    generation, management, and user access.
  • The list of accepted papers.
  • The conference program includes three interesting
    workshops, namely
  • International Workshop on Interacting with
    Multimedia Content in the Social Semantic Web
  • Cross-Media Information Analysis, Extraction and
    Management
  • Semantic 3D Media
  • The conference program also includes three
    tutorials
  • A Semantic Multimedia Web
  • Ontologies and the Semantics of Visualization
  • Creating Semantically Rich Virtual Reality
    Applications.

8
Semantic Infrastructure for Grid Computing
Applications
  • In the context of Grid computing, topics of
    interest include
  • Integration of rich semantics in grid
    architectures
  • Ontologies and semantic services for grid
    applications
  • Automatic capture and annotation tools for
    semantic-based data description
  • Semantic-based searching tools
  • Scalable, flexible, lightweight systems and
    technologies
  • Ontology repositories and maintenance
  • Virtual data stores
  • Instantiable architectures for semantic systems
  • Convergence and/or interoperability of Grid and
    W3C standards
  • Semantic-based improved interoperability
  • Federations of semantic systems for cross-linking
    data files between independent data grids.
  • Data grid semantic issues related to control
    mechanisms and state information
  • Preservation semantic issues related to
    authenticity and technology evolution.

Autonomous Semantic Robots (ASRs)Discussion on
Behnam Rahnamas Presentation
  • Review the presentation again.
  • Questions
  • Are ASRs plausible?
  • Feasible? Practical?
  • Are there technical issues?
  • Are they surmountable?
  • Are ASRs useable?
  • Are ASRs ethical?
  • Other issues?
