+ROC Data Model Conventions and Requirements
+-------------------------------------------
+
+The MEGA-Patch described above will bring up a fully compliant sample data model.
+However, it may be useful to bring up your own data model, customized to a different
+site of sites. This subsection documents conventions and requirements for the Aether
+modeling within the roc.
+
+The ROC models must be configured with the following:
+
+* A default enterprise with the id `defaultent`.
+* A default ip-domain with the id `defaultent-defaultip`.
+* A default site with the id `defaultent-defaultsite`.
+  This site should be linked to the `defaultent` enterprise.
+* A default device group with the id `defaultent-defaultsite-default`.
+  This device group should be linked to the `defaultent-defaultip` ip-domain
+  and the `defaultent-defaultsite` site.
+
+Each Enterprise Site must be configured with a default device group and that default
+device group's name must end in the suffix `-default`. For example, `acme-chicago-default`.
