Why isn't there a database of ontologies?

Question

A bank statement, a sales order an invoice and numerous other entities can be pretty much distilled into some sort of ontology.I have bumped into some attempts but they seem pretty much abandoned.Why hasn't something like this come to fruition?

For the examples you gave, any introductory accounting textbook will describe and explain the artifacts of commerce and bookkeeping.I don't think anyone can answer the "why" question you ask. I would guess because no one thinks such a database would serve any useful purpose, compared to the more usual ways to learn about entities and relationships. Using "ontologies" in a sentence does seem cool, I admit.

What exactly is an ontology? Outside of academic philosophy, is it just a schema?
