CSIT600c Web Services Programming Summary and
Outlook

• Dickson K.W. Chiu
• PhD, SMIEEE

2
State of Web Services

• Consider the adoption time required XML
• Consider the time between the invention of HTML,
  XML and Web Services
• Technology/Standards are still evolving
• SOAP, WSDL, UDDI are not enough
• Being adopted in phases see how public few web
  services now (2005)
• 1st phase (current state) - Concerted deployment
  internally within an organization, mainly for
  interoperability
• 2nd phase - Selective and non-aggregate
  deployment with trusted outside business partners
  (Private registry deployment)
• 3rd phase - Wider, more dynamic, and aggregate
  deployment with outside business partners (Public
  registry deployment)

Web Services Development Methodology

• Web Wrapper for Web Services - WebXcript
• Extension from human to program interface eNSS
• B2B Process Collaboration
• Beyond normal executions - events and exceptions
• Extending Web services to mobile users - 3-tier
  view-based m-service adaptation
• Adapting processes / services to different
  business partners - B2B interaction management
  with flows and process views
• Handling urgent processes / services - Alert
  driven E-service management
• Inter- and intra-enterprise integration -
  Financial Enterprise Content Management
• Security and Privacy Control

Semantic Web Services

• Resources
• http//www.daml.org/services/ (RDF -gt (DAML /
  OIL) -gt OWL languages)
• http//www.w3.org/2001/sw/
• B2B
• semantic mediation between different
  organizational vocabularies
• service models and protocols
• Grid
• widely distributed large-scale heterogeneous
  computing
• Ubiquitous
• portable devices
• extremely dynamic variation in available services
  
• Web
• ability to dynamically discover and combine web
  services under the control of software agents
• comparative shopping, coordination of specialized
  business services (e.g. travel plans, meeting
  arrangements...)
• Agent
• distributed planning and control or coordination
• Logistics

Semantic Web Services Applications

• Service invocation planning (message formulation)
  and response interpretation based on process
  descriptions
• Choreography (protocol) interpretation and
  execution
• Semantic translation/mediation (e.g., of message
  content, process descriptions or advertisements)
• Candidate service identification (matchmaking)
  and selection
• Automated Process composition
• Process mediation and delegation
• Service process status tracking
• Ontology management and access
• Security (including identification,
  authentication, delegation and policy-based
  authorization)
• Reputation services
• Service failure handling and compensation
• Negotiation and contracting
• Server executable process management (service
  factories, instantiation, migration)

Final Words for the Course Paper

• Please start early.
• Any novel ideas and topics are encouraged and
  will be much positively rated.
• New topics may not necessarily be difficult
  they could be easy because any ideas that make
  sense can be good new ideas.
• I will give you directions and feedback to your
  proposals / abstracts.
• I shall even try to publish the best papers with
  you to workshops, conferences, and/or journals
  for the honor of you, the class, and the
  department.
• I assume you agree if not, please let me know
• Good luck Thank you Good bye!
