Deliverable 7.5- ENVISION Open Source Strategy
Executive Summary:
ENVISION targets the implementation of Web-enabled pluggable user interface components for the creation of domain-specific Web sites for the environmental modelling community. This includes tools for the discovery, semantic annotation, and adaptive composition of workflows representing the environmental process models. Several reasons justified the decision to publish all the developed components under a permitting open source license. This deliverable will discuss these reasons, and explain the strategy which we have successfully applied in the project.

Marcell Roth (from IFGI, University of Münster) has won the second place at this year’s 52°North Student Innovation Price with his work about Geographic Feature Pipes. His implementation includes the Service Model Translator (SMT), which also forms an integral part of the ENVISION platform. Marcell received the price from Mrs. Svenja Schulze, North-Rhine Westphalia’s Minister of Innovation, Science und Research. He also presented his work (and some words about ENVISION) on the Geoinformatics 2011.
The awardees, Marcell from IFGI is second from left.
The following summary of Marcell’s work (as well as the attached picture) is taken from the announcement published on the 52°North website.
Second prize winner Marcell Roth proposes Linked Data as a trendsetting way to solve the problem of linking and aggregating data coming from different web services. OGC standards are combined with subject-specific ontologies to analyze complex spatial or spatio-temporal questions. The Geographic Feature Pipes portray a process for translating data from OGC Web Services in to the Linked Data Model. This process can also be used to continually update spatially dynamic Linked Data data sets. Thus, Geographic Feature Pipes help to build up the Geospatial Semantic Web. 52°North considers this technologically oriented proposal important for future development of spatial data infrastructures.

The journal article “Geospatial Standards for Web-enabled Environmental Models” has been published on the International Journal of Spatial Data Infrastructures Research. This paper is a joint effort by ENVISION (George Athanasopoulos from the National & Kapodistrian University
of Athens, Patrick Maué from University of Münster) and UncertWeb (Christoph Stasch and Lydia Gerhartz, both from University of Münster). Here is the abstract:
Serving geographic information via standardized Web services has been widely accepted as a useful approach. Web-enabled environmental models simulating real-world phenomena are, however, rare. The models predict observations traditionally served by geospatial Web services compliant to well-defined standards. Using standardized Web services could support decoupling of models, comparison of similar models, and the automatic integration into existing geospatial workflows. Modeling experts face several open issues when migrating existing environmental computer models to the Web. The selection of the Web service interface depends on the input parameters required for the successful execution of the computer model. Losing control over the execution of the models, and consequently also the confidence in model results, can be addressed to a certain extent by using translucent and standardized workflow languages. Mechanisms and open problems for the implementation of geospatial Web service compositions are discussed. Two scenarios about oil spills and the exposure to air pollution illustrate the impact of unconfigured model parameters for standard-compliant spatial data clients.
