Add "ParameterURL" metadata field #101

Closed Lestropie closed 4 months ago

Lestropie commented 4 months ago

One aspect of the "model fit parameters" vs. "model-derived parameters" distinction is that sometimes an individual can propose taking the outcomes of some model fitting process and compute some novel derivative measure from those data, and the relevant reference for that derived parameter may be different to that of the model itself. Eg. The original 1994 DTI paper doesn't present FA.

With #92, metadata relating to "the model" is encapsulated within its own metadata dictionary, and there a URL can be provided for the model. With this PR I propose that in some instances it may be desired to provide a URL that describes just the specific parameter that is encoded in the corresponding data file.

Oh - interesting! Yes, I think that the 1995 is the correct reference here, and also yes: I think that paper has a math error in it (I see no other explanation). Funny.
