The primary project objective is to develop an ICT framework, which enables software and service providers (SMEs, RESs, INDs) to generate and establish open, extensible and reconfigurable development platforms for Web-Service applications. Established in such a way the open platforms consist of coupled and linked INFRAWEBS units, whereby each unit provides tools and adaptable system components to analyse, design, conjointly compose, and maintain services (SW services) within their whole life cycle. Due to the versatile and modular structure, the proposed framework enables the handling of a broad class of services.
The sub objectives for this project are to develop a software framework to:
- provide a comfortable and "easy to use" knowledge brokering unit,
- used within a collaborative workflow and platform environment for analysis, design and composition
of SW services
- supplemented with secure and privacy preserving run-time and maintenance tools.
These sub objectives will be achieved by developing and realising software and system components consisting of:
- an ontology and similarity based organizational memory and tools for extracting and retrieving specific
knowledge and information for SW services, and
- a P2P agent-based interoperability environment (Distributed SW service repositories) for CBR based
design and composition of SW services (CASE-tool), and
- a run-time module for supervision (Executor,QoS-Broker) and maintenance considering security
and privacy aspects
In this way the innovative integration and "closed loop" feature of the INFRAWEBS approach persists in the semantic based coupling of service processing issues to knowledge brokering structures of the entities: service handling actions and knowledge management actions are integrated (Integration of the tripartite SOA - service requester / provider / registry - approach with information brokering modules).
Several non-functional aspects are addressed and covered by applying a set of powerful (AI-) methodologies: Interoperability and dynamic adaptability are achieved by exchanging semantically enriched services among open platform partners within P2P environments. The machine processability of ontology based structures in conjunction with "closed loop" approaches within the service operation, maintenance and feedback cycle (QoS) ensures implicitly a high degree of adaptability, as well as the establishment of scalable, extensible platform structures (self-organising structures). Service composability is guaranteed by applying open standards and specifications like XML, RDF(S), BPEL4WS, WSFL, WSIL, WSML, WSMO etc. Archiving experience feedback patterns in distributed rule and case bases (CBR) within distributed decision making processes, ensures customisable modular development environments for supporting and initiating innovative evolving processes.
Due to commonly processed research projects, the consortium partners take up existing RTD results and system modules related to Semantic Web technology - therefore no foundational research but applied research has to be done in the area of Semantic Web.
