Automatic Resources/Services Discovery

Upon request, generate lists of available services which meet a given set of functional requirements.
Non-functional requirements such as performance are not usually considered at this stage. However, a subsequent task of service selection may use non-functional requirements to rank the candidate list in order to make a particular service selection.
Syntactic description focus on the format of messages exchanged between client and provider.
Semantic descriptions provide information about what the client requires and what the service provides in terms of relationships between inputs and outputs.
Quality of Service considerations such as performance, reliability, cost etc are essential in making a service selection
Business Data ontologies describe the data which is exchanged by the services. These may be generic, or specific to a particular industry.
