The design proposed here can operate across many separate DL systems. The issue of who provides both the data
and quality control over the data in the FRBR database is
clearly critical, given that many users and systems will rely
on this vital resource. Though such issues are beyond the
technical emphasis of this paper, others such as Mimno et al have discussed this issue. The reliability of the FRBR
data used will have a direct effect upon the usefulness of
the FRBR-based services provided in a system, and their
long-term credibility.
