Does anybody know of a plugin or R/Python/Java library that treats YAML properties as a dataframe?

I am asking the question because having so many notes -in the thousands - having different set of YAML properties, I was wondering if anyone has found a way to standardize the properties by groups they belong to. For instance, I have templates for YAML properties by (i) objects; (ii) concepts; (iii) disciplines; (iv) companies; (v) industries; (vi) locations; (vii) people; (viii) Realms. Their properties are the same for the same group or template.

But with time the older notes were left behind in updating their properties. It occurred to me that treating the YAML properties as columns, we could move, add, remove columns as we would do in dataframes.

Any suggestions?

I think R Markdown offers convenient API to yaml header, see
