Persistence

There are three kinds of objects that are considered on the system:

Tree objects

Called Resources that implement guillotina.interfaces.IResource. This object has a __name__ and a __parent__ field that indicate the id on the tree and the link to the parent. By themselves they don't have access to their children, they need to interact with the transaction object to get them.

Nested

Objects that are linked at some attribute inside the Tree object, this object are serialized with the main object and may lead to conflicts if there are lots of this kind of objects.

It can belong to:

• A field that is an object

Nested References

Base objects that belong to a specific object, it is big enough to have its own entity and be saved in a different persistence object. Its not an element of the tree.

It can belong to:

• An annotation that is stored on a different object
• A BaseObject inherited field object
