Equivalent of ERD for MongoDB?

Question

What would be the equivalent of ERD for a NoSQL database such as MongoDB?

Answer 1

I know of no standard means of diagramming document-oriented "schema".

I'm sure you could use an ERD to map out your schemata but since document databases do not truly support--or more importantly enforce--relationships between data, it would only be as useful as your code was disciplined to internally enforce such relationships.
