* The transitive closure of an Entity relationship can be expressed via the _Loop_ expression. A
_Loop_ expression can be any traversal (recursively a query) that represents a _Path_ that ends in an Entity of the same _Type_ as the starting Entity.
* The _WithPath_ clause can be used with transitive closure queries to retrieve the Path that
connects the two related Entities. (We also provide a higher level interface for Closure Queries see scaladoc for 'org.apache.metadata.query.ClosureQuery')

* There are couple of Predicate functions different from SQL:
* _is_ or _isa_can be used to filter Entities that have a particular Trait.
* _has_ can be used to filter Entities that have a value for a particular Attribute.
