Discovery
Discovery is the act of locating a machine-processable description of a Web service-related resource that may have been previously unknown and that meets certain functional criteria. It involves matching a set of functional and other criteria with a set of resource descriptions. The goal is to find an appropriate Web service-related resource
Discovery_Service
A discovery service is a service that enables agents to retrieve Web service-related resource descriptions
A discovery service is a service
Identifier
An identifier is an opaque string of bits that may be used to
associate with a resource.
Representation
A representation is a piece of data that describes a resource state.
Resource
A resource is defined by [RFC 2396] to be anything that can have an identifier. Although resources in general can be anything, this architecture is only concerned with those resources that are relevant to Web services and therefore have some additional characteristics. In particular, they incorporate the concepts of ownership and control: a resource that appears in this architecture is a thing that has a name, may have reasonable representations and which can be said to be owned. The ownership of a resource is critically connected with the right to set policy on the resource.
Resource_Description
A resource description is any machine readable structure that may
permit resources to be discovered. Resource descriptions may be of
many different forms, tailored for specific purposes, but all
resource descriptions must contain the resource's identifier. (2.3.3.6.1)
