ABSTRACT The primary project objective is to develop an ICT framework, enabling software and service providers to generate open and extensible development platforms for web-service applications. The open platform consists of coupled and linked Infrawebs units, whereby each unit provides tools and adaptable system components to analyse, design and maintain web-services realised as Semantic-Web-Services within the whole life cycle. The Infrawebs units will be used to establish an open development and collaboration platform for SMEs and strong industrial suppliers for software and services. This offers a new dimension of collaborative work and service production, service provision and service maintenance in run-time environments.

OBJECTIVES To provide a comfortable and “easy to use” knowledge- brokering unit, Being used for analysis, design and composition of SW services within a collaborative workflow environment, and Supplemented with security and privacy preserving run- time and maintenance tools

State of the Art A state-of-the-art analysis has shown the lack of systems for effective collaboration in reconfigurable networks, as well as adaptable platforms for the design, deployment and maintenance of Web Service enabled applications. The present and existing software tools and systems are mostly incoherent and static, which in the majority of cases, is due to proprietary aspects or features preventing an effective adjustment and balancing of information pools. This is also a reason for missing re-configurability, adaptability and self-organising features of existing development and networking platforms.

VISION …The step from creating just "static" to creating and maintaining "dynamic" (semantic) web services through the machine-processability feature of semantically structured information sources and domains. To this end, a bridging of Web Services and Semantic Web technologies will be implemented in the context of rich semantic service descriptions and inferencing capabilities.
