RelationType

The RelationType class represents a relation definition between two node types (content or media). For example keeping track of node usage across the site, in order to avoid deleting content that is used else where. When querying a relation, it is typically done using the parent node key. However, if the RelationType is bidirectional, querying with the child node key is also possible.
