Some Thoughts about Web Services

Some Thoughts about Web Services
2
Vision

• Ordinary People are able to create, use, and
  share service compositions (not only programmers
  in companies connecting workflows)
• Find a cheap hotel close to the MIT faculty
  club
• In which bookshop within 5 miles can I pickup
  the Lord of the Rings?
• How can I go to the airport?

3
Claims

• CRITICAL Simple Process Model
• CRITICAL Sharing of Web Service Specification
• Libraries of Web Service Process Specifications
• CRITICAL Get User Community quickly
• User Community not necessary industry/academics
• How to overcome chicken/egg problem (creating the
  Web all over again)
• NOT CRITICAL automated composition, deep
  semantics, inference, plethora of features

4
Process Primitives

• Dataflow, Control Flow, Datastores, Ontologies
• As simple as possible (add features if spec is
  useful)
• Conceptual Model that supports sharing and
  building critical mass
• Incomplete service specifications (so that I can
  complete them)
• Link to remote service specification
• Import by reference
• Notion of an Adapter
• So that I can adapt an exiting specification I
  imported by reference
