"'A web of data' is a well conducted explanation of the Semantic Web. From the beginning, Tim Berners-Lee and the W3C expected the Web to become a place that allows humans and machines "to start off in one database, and then move through an unending set of databases which are connected not by wires but by being about the same thing." In the Semantic Web, data is annotated with unambiguous definitions and connected by meaningful links. The entire Web thus becomes a network of machine-processable data (including links, which are also data in another
The Ontology Web Language for Services (OWL-S) is a “core set of markup language constructs for describing the properties and capabilities of Web Services in unambiguous, computer-interpretable form.” When fully realized, OWL-S will allow service providers or brokers to define their services based on agreed upon ontologies that describe the “real world” functions they provide. OWL-S was originally called DARPA Agent Markup Language for Services (DAML-S), and was created as part of the DARPA Agent Markup Language (DAML) project.
The goals of
As the set of available Web Services expands, it becomes increasingly important to have automated tools to help identify services that match a requester's requirements. Finding suitable Web services depends on the facilities available for service providers to describe the capabilities of their services and for service requesters to describe their requirements in an unambiguous and ideally, machine-interpretable form. Adding semantics to represent the requirements and capabilities of Web services is essential for achieving this unambiguity and
