The necessity of intensive development of tools supporting Semantic Web Service (SWS) technology and especially WSMO initiative has been clearly recognized in WSMO community. Several such tools have been developed or still under development (see http://www.wsmo.org
). Most of them are oriented mainly to the researchers and developers, working in the area of SWS technology. The creation of SWS is done by using structural text editors, which of course simplify the process for creating semantic description of a service, but still request strong knowledge of WSML – the logical language used for describing SWS and goals in WSMO.
A different approach is proposed in the INFRAWEBS Designer
- a graphical, ontology-based, integrated development environment for designing WSMO-based SWS and goals.
The INFRAWEBS Designer does not require any preliminary knowledge of WSML
The most important characteristics of the Designer are:
User-friendliness: it proposes an intuitive graphical way for constricting and editing service and goal descriptions, abstracting away as much as possible from the concrete syntax of the logical language used for implementing it. The WSML description of the semantic object under construction is automatically generated from the graphical models created by the user.
Intensive use of ontologies: the process of constructing logical descriptions of semantic objects is ontology-driven - in each step of this process the user may select only those elements of the used ontologies that are consistent with the already constructed part of the object description.
Reusability: creation of semantic descriptions is a complex and time-consuming process, which can be facilitated by providing the designer with an opportunity to reuse existing, similar descriptions, created by the designer herself or by other users. The INFRAWEBS Designer provides the user with such an opportunity by applying the case-based reasoning approach.
