Vocabularies are a “search device”: they organize information for some
specific users’ needs (are you a statistician working for Health
planning or a surgeon searching for similar articles on topics related
to surgery procedures ? Are you a member of the European Parliament
working on transport regulation or an Eurocontrol Engineer working on
specific air control problems ? etc. etc.)
Real re-use of vocabularies is much more problematic than expected (most
of the times).
Alignment of different of vocabularies is often flawed for the same reason.
We therefore needs dynamic ways to compare and relate vocabularies to
create and MAINTAIN new ones. We do not need so many kind of logic
relations apart from conceptual heritage hierarchies and (annotated)
matching relations. But we need very visual tools to keep different
vocabularies in parallel and synchronized.
Hoping those very general thoughts (born from many failures to have end
users really involved in information bases) can help,
