That's a great resource. We've tried to be consistent in using these terms. I think a lot of the confusion and lack of standardization over terminology came from the fact that database and distributed systems research had less overlap in the past...

Consistency in the ACID sense meaning something different from CAP Consistency is another good example.

Another point that often gets lost when talking about ACID guarantees is the maximum scope of a transaction that a system supports. There are many systems which support ACID guarantees for a single record or shard, but fewer that can support fully distributed transactions across a sharded dataset in a scalable manner.
