Add the following values to the model. 
MODELTYPE = ERD
SYSTEMS = Entities
INTERACTIONS = Relationships.
The available system and interaction TYPEs can be determined from https://revelation.microplatforms.com/app/reference/data/refData.json which defines the allowable SystemType and InteractionType for the ERD Model under MODELTYPE and. For interactions, the relationship represented is described by the corresponding LongDescription under INTERACTIONTYPE.
For each entity and relationship add important metadata. The TEXT property of relationships should be an empty string.
