@iMichaela I posted this comment in the OSCAL Foundation slack also. Creating this issue to capture it.

I looked at the v1.2.0 release of OSCAL with mapping model and here is the JSON outline -

The confidence-score has a STRVALUE field which I don't remember was discussed in the call (I may have missed that discussion), and there is no description of it. We already have a category field and percentage field, so not sure what does it represent. Similarly coverage also has that field. I believe coverage was a simple field with decimal value. Also, the name STRVALUE does not seem appropriate as it is of type decimal. Since the schema was not available earlier these differences were not clear. Moreover, not sure how the generation-method is to be used.
