Which Service Interfaces fit the Model Web?

Ponència presentada a The Fourth International Conference on Advanced Geographic Information Systems, Applications, and Services, GEOProcessing 2012, celebrat a València del 30 de gener al 4 de febrer de 2012The Model Web has been proposed as a concept for integrating scientific models in an interoperable and collaborative manner. However, four years after the initial idea was formulated, there is still no stable long term solution. Multiple authors propose Web Service based approaches to model publication and chaining, but current implementations are highly case specific and lack flexibility. This paper discusses the Web Service interfaces, which are required for supporting integrated environmental modeling in a sustainable manner. We explore ways to expose environmental models and their components using Web Service interfaces. Our discussions present work in progress for establishing the Web Services technological grounds for simp lifying information publication and exchange within the Model We b. As a main outcome, this contribution identifies challenges in respect to the required geo- processing and relates them to currently available Web Service standards
