References between objects in loosely coupled distributed
information systems pose a problem. On the one hand, one tries to
avoid referential inconsistencies like, e.g., dangling links in the
WWW. On the other hand, using strict constraints as in databases may
restrict the data providers severely. We present the solution to
this problem that we developed for the Nexus system. The approach
tolerates referential inconsistencies in the data while providing
consistent query answers to users. For traversing references, we
present a concept based on return references. This concept is
especially suitable for infrequent object migrations and provides a
good query performance. For scenarios where object migrations are
frequent, we developed an alternative concept based on a distributed
hash table.
