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  reasons are no longer valid, except for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

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.

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?
