Introduction
For DigiHaven we have introduced a record tree with metadata inheritance, where metadata is inherited from the top of the tree to the children below. For MediaHaven 2.0 will be gradually moving from a partial structure to a full tree structure with representations as for DigiHaven as shown in the trees below. The page Record Tree Glossary provides an overview of different terms used to describe the record tree.
Trees
The following pages show diagrams for MediaHaven and DigiHaven. In the Use Cases we describe additional hypothetical examples of trees.
Rules
A record can have at most 1 parent
No loops are allowed within the tree
Examples of records with no parent are the records at the top of the tree such as the Series or Classification
Because no loops are allowed within the tree
A record cannot be a parent or child of itself
A record cannot be adopted by one of its (grand)children or (grand)parents
Inheritance
Metadata field definitions can be marked as inheriting.
When a record is created or adopted under a parent record, the inheriting metadata fields will be copied from the parent to the child record
When the metadata changes of a parent record then the changes made to inheriting metadata fields will propagate to its children asynchronously
