- A predicate map is a mapping function which emits a URI derived by concatonating the stem URI, relation name, and the attribute name, separated by puntuation discussed below. The (infinite) set of URIs which are produced by a predicate map given a particular relation are said to be in that relation. A predicate unmap is the reverse function, parsing a URI in a relation to derive the stem URI, relation name and attribute name. These are called the predicate's stem, predicate's relation, and predicate's attribute respectively. If the predicate's attribute is a foreign key, the predicat's target is the attribute's target. If the predicate's attribute is not a foreign key, the predicate's datatype is the datatype of the predicate's attribute.
