CONCLUSIONS
• The Model Web aims to support the science of tomorrow building an ecosystem of interacting models and facing the related challenges (i.e. multidisciplinarity, scalability, etc.).
• In the Model Web users focus on high-level representations (i.e. abstract Business Processes); lower level details are in charge of the middleware.
• Building meaningful multidisciplinary BPs requires knowledge bases supporting the interaction with and between Science and Policy components
• The GEO URR can provide the knowledge (applications/BPs, lexicon/vocabularies) required to implement the GEO Model Web vision.
