I recently read that YAML has a way of specifying a "sequence of sequences" which could work for tabular data like that in your example. i.e - [Server,Subnet,IP] - [db01,databases,10.1.2.3] - [db02,databases,10.1.2.4] - [user01,filers,10.3.10.1] - [user02,filers,10.3.10.2] That being said, the CSV does seem more straightforward.
