an evaluator receiving, via an application programming interface, a query from an application executing on a client device, the evaluator embodied on non-transitory computer memory including instructions translatable by at least one processor, the query containing a predicate; the evaluator processing the predicate using a tree structure containing nodes representing objects and edges representing relationships thereof, the processing including applying filters to attributes of the relationships to identify a first set of objects that are relevant to the predicate, the processing further including navigating along each incoming role of a relationship and from there via an outgoing role to other objects to identify a second set of objects that are relevant to the predicate, wherein the evaluator determines an object as relevant to the predicate if at least a value of a field of the object is equal or similar to a value of the predicate; and responsive to the query, the evaluator returning identifiers associated with a united set of the first set of objects and the second set of objects to the application. |
