User Code integration and provenance management in the VERCE computational platform

Within the EC project VERCE (Virtual Earthquake and seismology Research Community in Europe e-science environment) one of the challenges is providing to the scientists a framework that allows the integration of their scientific code within a streaming workflow system. In this context, the distribution of the data and the computational resources accessible during the execution of the workflow will definitely make the validation, reproducibility and traceability of the results more complicated. Therefore, the production and harvesting of provenance metadata is required, aiming to a better understanding of the computational outcome.
In this talk we present these challenges referring to a real life scientific use case and how the problem has been tackled by extending the ADMIRE framework, which is currently the core workflow system adopted by the VERCE platform.
