Final Activity Report Summary - RSSGRID (Reasoning Services for the Semantic GRID)

This project produced two major results that had an important impact in the academic community.

Firstly, the Semantic open grid service architecture (S-OGSA) was the first reference architecture for the development of semantic grid applications. Guided by a set of design principles which aimed at maximising the architecture impact and uptake by means of a minimal impact in the current grid architectures, S-OGSA identified a set of semantic provisioning services that had to be provided in any semantic grid applications and classified them according to the knowledge entities that they dealt with, e.g. ontologies and metadata. Apart from that, this architecture defined the concept of semantic binding as a container of metadata that related any set of grid entities, i.e. both resources and services, with a set of knowledge entities. By treating knowledge entities and semantic bindings as first-class grid entities, aspects like the stateful management and the lifecycle of metadata were more easily addressed. Finally, the architecture identified the most common patterns of interaction that could occur in the development of semantic-aware grid services.

On the other hand, Active ontology (ActOn) was an information integration service especially designed for situations where information sources were highly dynamic and overlapped, thus requiring the selection of the most appropriate information source whenever a user request was made. Moreover, in these situations user requests had to be dealt with in real time, hence requiring maintenance of a cache of metadata with a good control of its lifetime.

These results were used, both during the project and beyond its lifetime, in the development of applications in different domains, such as car insurance, satellite image quality analysis, detection of coral bleach and management of lifecycle of computational biology experiments in the case of S-OGSA, and grid information service development for the 'Enabling grids for enabling e-Science' (EGEE) production testbed.

The results were disseminated via publications in relevant workshops, conferences and journals, invited talks and seminars at universities, conferences and summer schools, and, finally, tutorials at international conferences.
