  9. W3C Web Services Architecture: “A Web service is a software system designed to support interoperable machine-to-machine interaction over a network. It has an interface described in a machine-processable format.” (HTTP)

  10. The OASIS SOA Reference Model group defines Service Oriented Architecture as a paradigm for organizing and utilizing distributed capabilities that may be under the control of different ownership domains. It provides a uniform means to offer, discover, interact with and use capabilities to produce desired effects consistent with measurable preconditions and expectations.

  18. tModel   Digg This!     StumbleUponDel.icio.us tModel A tModel is a data structure representing a service type (a generic representation of a registered service) in the UDDI (Universal Description, Discovery, and Integration) registry. Each business registered with UDDI categorizes all of its Web services according to a defined list of service types. Consumers can search the registry's listed service types to find service providers. When providers want to make their specification-compliant services available to the registry, they include a reference to the tModelKey for that service type in their bindingTemplate data.
