RO-Crate profile approach

[lauportell]

Currently working a RO-Crate profile of Treecript outputs.
In yesterday's meeting, @wna-se said it would be great if we could include the approach you are following for this in here so that we are all aware.

The idea is just taking as a starting point the Workflow Run RO-Crate profiles, as they can be used to both describe processes and workflow executions, and they also have an example about attaching technical metrics related to executions (see https://www.researchobject.org/workflow-run-crate/profiles/provenance_run_crate/#representing-resource-usage ).

The part which is not covered is the case of timeseries of sets of metrics, where several different kind of metrics are gathered periodically. Two relations have to be described, which are the co-occurrence of the sampling (i.e. different metrics gathered at once), and the order of the samples (same metric, gathered several times, related by which one happened before and which one happened after).
