Web Services Architecture Document

The Web Services Architecture Working Group has essentially completed a
set of WS architecture documents.  "Essentially" here means that the
meaningful content is now frozen, but the working version documents
linked below need some mechanical editorial work in order to put them in
shape for publication as W3C Notes.  For example, not all of the links
have been put in properly, the "document status" does not read
correctly, figure numbers need correcting and so on.

Web Services Architecture OWL Ontology: The following link is to a work
area containing files that will be combined and significantly cleaned
up.  Please do not try to use these ontologies as-is in inference
engines: http://www-2.cs.cmu.edu/~softagents/WSA_Ontologies/
Web Services Management Architecture and Implementation: (The following
documents require a lot of mechanical publication work which is underway
as I write this note):
  - Elements and Relationships:

  - Endpoint Management:

  - Service Lifecycle:

As I have posted before, my personal belief is that there is a great
deal of valuable content in these documents.  This architecture
substantially meets the requirements defined in the charter and the
requirements document with the exception of some issues related to
security and privacy.  Although the architecture contains substantial
material concerning security and privacy, more work is needed.  The
working group was not able to address these issues with the available
resources;  Security is very much an area that requires specialized
expertise and during much of the lifetime of the group we did not have
active members with such expertise.

Contributions of this work include the following:

 - Provides a coherent framework that allows specific technologies to be
considered in a logical context and facilitates the work of
specification writers and architects.

 - Defines a consistent vocabulary, including an authoritative
definition of "Web service" that has received widespread acceptance in
industry.

 - Defines an OWL ontology of Web services architecture concepts.

 - Distinguishes SOA from distributed object architecture.

 - Clarifies the architectural relationship between the Web and Web
services.

 - Clarifies the relationship between Web services and REST.

 - Identifies gaps and inconsistencies in existing Web services
specifications.

 - Identifies the role of semantics and the need for machine-processable
semantics and ontologies in Web Services.
