Procedure vs Assay and where to put Experiments, Analytical Workflows, and Files

[diatomsRcool]

What is the different between Procedure and Assay?
Where would an experimental procedure or an analytical workflow/procedure fit in the model?
Do we need to add Experimental Procedure and/or Analytical Procedure as a child of Procedure? Are experiments included in Lab Procedure?
See the Analysis node types in the BDC Gen3 documentation for some examples of Analytical Procedures.
See the properties of "Read Group" for examples of metadata that might be attributes of an Experimental Procedure element.
I suspect some File types in Gen3 result from analysis of other File types, procedures, and assays so, this has bearing on how Files are modeled as well.

a Procedure in this model was conceived as a healthcare procedure, either diagnostic or therapeutic. so things like an MRI, phlebotomy, surgical resection, cardiac ablation. this wasn't originally intended to cover metadata about assays or analytical workflows. are those things that need to be covered in this pilot? if not i would suggest we defer modeling those until we have addressed all the pilot items

[diatomsRcool]

I think a way to find out how much of the model we need for the pilot is to look at the priority variables and figure out which parts of the model are needed to manage those.

[bfurner]

Right, I hadn't seen anything in the variables which indicated we needed to model experiments or analytical workflows which is why I asked. The variables seem to be entirely clinical.

OK, I'll leave this issue open for the moment, but we won't worry about it until after the pilot.
