D5.3 – Integration of the open source catalogue with the semantic discovery engine – Version 1

Executive Summary:

This document proposes an approach to integrate semantic discovery into the OGC open source catalogue. The resulting artifact, which we call Semantic Catalogue, provides search functionality enabling users to discover the relevant OGC resources and services in a more precise way than using standard OGC catalogues. This document revisits how service discovery is currently implemented in standard OGC catalogues, identifies limitations of existing approaches and proposes a novel approach that integrates  semantic  discovery  with  the  OGC-based service discovery. The integration is realized at various levels.

At the level of query modeling, extensions of the OGC query language are defined by adding a new operator to support semantic constraints. At the architectural level, an integrated architecture is proposed that brings together OGC components (e.g. OGC open source catalogue) and semantic components (e.g. IRIS reasoner). Finally, this document reports on the status of the implementation and the future steps for integration of  the open source catalogue with the semantic discovery.
