Message Strategy:

A unique event on a contract should have its own unique message type.

Event schema changes on contract result in a new message type of the same name, with an incremented version affix, and updated messageSchemaVersion

Message Naming Schema Rules:

Message names and their associated data types should adhere to the following rules:

• Message names contain both the noun being acted upon and the verb of the action taking place. E.g. DomainCreated, DomainRoyaltyChanged
• Message names that adhere to the above but cause a collision with an existing message name should be prefixed with the contract source. E.g. EE_DomainCreated
• Message data types begin with the message name
• Message data types are affixed with their schema version - E.g. DomainCreatedV1
• Message data types end with Data

Identifying Messages:

The contents of a message can be identified by it's message name: event, and the schema version messageSchemaVersion. These correspond to a MsgDataType that describe the schema of the message.
