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.

Our workshop about Environmental Information Systems and Services at this year’s EnviroInfo was a great success. We had thirteen presentations from a wide range of projects with related research objectives. You can find more information about the workshop, including the call and a description at the website. It does also contain links to the proceedings (hosted by CEUR-WS), videos (hosted by Videolectures) and slides.

At our last project meeting back in September, we planned one day as collaborative project with the members of the UncertWeb project (since both project meetings shared time and location). In short, the UncertWeb project will result in mechanisms, standards, tools and case studies to enable uncertainty management in an interoperable model web context. A nice introduction (video) into the project is given by Edzer Pebesma (also from the University of Münster) at our workshop at the EnviroInfo conference.
Uncertainty is a topic which we can only marginally cover in ENVISION. It is itself a very deep topic with lots of things to taking care of. The collaboration already resulting in first publications, in the future we hope to further push the cooperation to be able to better cover uncertainty in the ENVISION project.
