The following demonstrator video (also available here) wraps up some highlights of the first project year. Due to the strict time limits we were forced to put as much information as possible in these ten minutes. More detailed videos which give you a bit more time to understand what is going on are following in the next few weeks.
Update: we’ve hit the bandwidth limit on screencast.com. If it doesn’t work for you, you can also directly download the video here:

D2.2 Environmental Semantic Web Portal Version 1 - Initial development and user guide
Executive Summary:
This deliverable reports on the first release of the ENVISION Portal. The ENVISION Portal allows the environmental community to use domain specific Web-Models or create new ones building upon the available resources. It is used by non ICT-Skilled users to produce websites dedicated to specific environmental scenarios, which embed web service compositions implementing environmental models. It is a generic solution to be used for different modelling domains and has to provide a community based system.
The first release of the ENVISION Portal provides:
- support of Community with authentication,
- resource management,
- an annotation mechanism,
- discovery of resources,
- a composition designer,
- a way to create new scenario websites,
- an access to dedicated websites.
This deliverable provides details on the aforementioned items and puts them in the context of the overall ENVISION architecture. The first release of the ENVISION Portal presented in this deliverable is functional and already available for internal use for the ENVISION consortium. Significant changes and improvements will be performed during the second and third years of the project and will be reported in the deliverable due for month 24 and month 34 of the project.

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.
