OASIS and UN/CEFACT support ebXML (Electronic Business using eXtensible Markup Language). Part of ebXML is BPSS (Business Process Schema Specification), yet another standard having a similar scope as BPEL4WS, WSFL, XLANG, WSCI, and BPML. It is also clear that far not all standards will be adopted by the workflow vendors. The problem of export from one format to another either exists. As a result, the world is confronted with too many standards that are mainly driven by concrete products and/or commercial interests. Many of developers prefer to ignore standardization proposals that are using not well-established process modeling techniques [3]. 2.3.2. Semantic Web and DAML-S “The Semantic Web is a vision: the idea of having data on the web defined and linked in a way, that it can be used by machines - not just for display purposes, but for using it in various applications...” [11]. Web services is seen as basic technology for Semantic Web, e.g. creating software will be just a matter of finding the right components on the Web and a specification document linking to these components. The new software is again just a resource available on the Web. The realization of this innovative idea is not easy, because present standards (WSDL, UDDI, BPEL4WS) cannot provide technically the required functionality for semantic search of components. According to [14], a description language for B2B e-commerce flow description should satisfy the following requirements: descriptions with high level of exibility and expressiveness. The ability to express semi- structured data, as advert description of Web Services and B2B iterations description, is required; descriptions need to share a common semantics and be able to use common vocabularies; descriptions should easily lend themselves to performing the operations described in the negotiation and matchmaking sections such as, matching of advertisements with queries;

10 validation of negotiation proposals; checking of two negotiation proposals to determine if an agreement can be made; descriptions should express restrictions and constraints. The special markup language DAML-S is being designed to capture these requirements. DAML-S is an initiative to provide an ontology markup language expressive enough to semantically represent capabilities and properties of Web services. DAML-S is based on DAML+OIL and the aim is to discover, invoke, compose, and monitor Web services. In DAML-S, each service can be viewed as a process and its Process Model is used to control the interactions with the service [9]. DAML-S beneficially gives the following advantages in comparison with existing standards [10]: Automatic Web service discovery . Involves the automatic location of Web services that provide a particular service and that adhere to requested constraints. Such information necessary for Web service discovery is specified as computer-interpretable semantic markup at the service registry or ontology-enhanced search engine could be used to locate the services automatically.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
