Associating data formats with a software package in codemeta

I've been suggesting a way to associate data formats with a software package in the OSSR such that a science platform can suggest software packages or notebook environments for certain data types. Codemeta and schema.org tend to use MIME format descriptions for this (e.g. image/fits or application/fits) which is a good match since that is what VO protocols tend to use as well. But actually including this information in codemeta isn't totally straightforward.

One possible way to do this is by using an "abstract" DataFeed with the appropriate encodingFormat and use that in the supportingData object of the codemeta description. With "abstract" I mean that it would not provide most of the normal elements that would describe a concrete data set. We could include an element in such a DataFeed that indicates whethere it is an input or output format for the software package.
