Info from ARC No. 186 February 2005.

EAC is used to structure name authority file information. It was developed in recognition of the fact that there is no one-to-one correlation between archives and their creators. It holds info about creators, their relationships with the archives, other people and organisations, bibliographic and museum materials. There has been some talk (2005) of embedding EAC within a future XML Schema for EAD.

EAC uses a DTD.
