What does everybody think about using reference/template models?

I had a look at the books, and I could not find any data vault 2.0 modeling in them.

A challenge in Data Vault because your RV is based on mapping your source systems to hubs, links and sats and **everyone** has different implementations of even the same source systems\*\*\*\*
Your derived needs (business vault) would also differ, so yea, ref models could accelerate your thinking on the model but are probably going to range from wildly different to how your business defined their data to discussing what hubs, links and sats are (i.e. not helpful at all).
Perhaps what you should look at is what the Business Architecture is, i.e. what are the business objects we care about in our industry
