Characterise processing use case by type of processing

For the processing within the SRCNet, several processing models are probably going to be relevant. One option could be that users start by interactively processing small amounts of data to tweak parameters of workflows, to continue on doing large-scale analysis on many files. It would be enlightening and helping in the discussion on how to best offer the capabilities of the system to the user, to have a view on the use cases that have been defined in  the use case document and map those to how the processing is expected to happen. This work will need to take place in collaboration with the science representation. Such an overview can for example inform about questions on the relevance of Workload Management Systems in addition to the Execution Broker, or on ephemeral interactive analysis options versus static ones.
