# Message Serializers Message Serializers will `serialize` an Event Message into Event Data and `deserialize` Event Data into an Event Message. These are generally used by the Message Repository classes and `serialize` is done before the event message is persisted to storage and `deserialize` is done on the data that is pulled out of the database. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
