As I understand the model, a dcat:Distribution may have multiple dct:format values, and by implication, those formats would be available via any dcat:accessService/dcat:DataService associated with that distribution. I think this addresses your first and second user story.

The third user story is about a dcat:DataService that is a data processing service, and agree that the current DCAT model does not handle this, but depends on the dcat:endpointDescription/rdfs:Resource object to provide information about operations, input and output formats, templates for URL parameters, etc. From the discussion in #432 it seems that the data processing functions included in the dcat:DataService definition are construed in the context of access to a particular dataset (subset, reproject, upscale, downscale, regrid...). 

Your user story (if I understand correctly) is about a data processing service that takes an input resource, does some processing, and returns an output resource.  There is other information one would want to have to make a searchable catalog for such data processing services-- for example, a 'function' property (e.g currency-conversion, CSV-to-DCAT-transformation, units conversion, geographic reprojection...). I think these kind of data processing services would need to be represented as another kind of dcat:Resource for a catalog.
