Outlines

• This presentation describes a solution to the
  educational systems creation a architecture and
  methodology of educational system creation based
  on web services and service agents

Web service

• Software services are discrete units of
  application logic that expose message-based
  interfaces suitable for being accessed across a
  network.
• Interoperability www.ws-i.org
• Basic profile standards
• SOAP
• WSDL
• UDDI

Service agent

• A service agent is a service that helps you work
  with other services. Often supplied by the
  provider of the target service, the agent runs
  topologically close to the application consuming
  the service. It helps both to prepare requests to
  a service and to interpret responses from the
  service.

Service oriented architecture

• Service oriented architecture is one where
  application is cut on the pieces called services
• Each service is invoked by messaging
• The semantics of the operations are around
  business functions

Conclusions

• Web services and Service agent based
  interoperability enables the creation of the
  scalable and flexible global educational systems
• To create global educational systems we need a
  modular suite of specifications that enables
  enterprises of any size and in any geographical
  location to conduct interactions over the
  Internet.
• IMS Global learning Consortium offers such
  specifications
