This (or something like it) makes a lot of sense to me. I've been at multiple organizations where there have been efforts to create these "data dictionaries" explaining the meaning of the data, especially when the schemas or APIs are not well designed.

But then manually writing documentation is obviously tedious and can typically only be written by the data team that knows the underlying data well, which is not always the best use of their time.

I'll definitely be following Syndetic and hope they can help crack this problem.
