Relationships between XBRL hypercubes, including implicit relationships, may be automatically determined based on shared dimensions. Once such relationships are understood, “generic” software (software that is not specific to a particular taxonomy) may be built to provide some or all of the following functionalities: determine, enforce, and/or encourage referential integrity; deduce (graph) ordered relationships between hypercubes; make inferences about those relationships; “join” or “split” hypercubes; create isomorphic and/or homomorphic views of a hypercube for user presentation; and/or assemble and order primary items (attached to hypercubes) in a logical (graph) order.
