I see a new job title coming into being - Enterpruse Data Librarian

40,000 data sets - even if many are just diff versions - is a ridiculous number to manage or even know about on a non full time basis.

Data driven decisions need data yes, but they also need people to know the data exists. And what it means.

And this is just external curated data - use this as the standard for what each department should be producting internally.

In fact that's a good idea - a data publishing standard - not just the data types / schema, but actually supplying it through a format that is consumable by others.
