Is it possible to write tags like json or gorm in Entity? How does this relate to DDD principles?

In an Entity, you can use tags like json or gorm to manage serialization and ORM behavior. For example, the json tag defines how the field will be named when converted to JSON, and gorm specifies how the field is mapped in the database.

However, from the perspective of DDD (Domain-Driven Design) principles, it is important that the Entity reflects business logic and is not overloaded with technical details. Tags are a technical implementation, and their use is permissible if they do not violate the purity of the model.

That is, tags can be used for convenience in working with infrastructure, but it is important to separate domain logic from technical aspects to maintain clarity and maintainability of the model.
