EATS

EATS (the Entity Authority Tool Set) is a web application for recording, editing, using and displaying authority information about entities. It is designed to allow for multiple authorities to each maintain their own independent data, while operating on a common base that means information about the same entity is all in one place.

EATS also comes with client tools for automatically looking up entities by name and adding TEI markup to those names.
