Issue with ComputationalWorkflow inputs and outputs

[albangaignard]

While working on Bioschemas validation for workflows, we found that none of the input or output parameters were retrieved with RDF parsers.

JSON-LD playground cannot get workflow inputs/outputs.
wf_18.jsonld.txt

There is also a warning when using the schema.org validator :

Possible workaround : when using this profile, input and output JSON-LD keys could be prefixed with another namespace, different from http://schema.org.

@albangaignard does this work correctly in the ComputationalTool type?
In any case, it'd be good if both are fixed in the same way.
