Info from various bits in ARC No. 186 Feb 2005.

EAD was originally developed in the 1990s. Currently (2005) EAD is only expressed as a 2002 DTD rather than a Schema. A proper, approved XML Schema would allow EAD finding aids to be harvested according to the Open Archives Initiative protocol.

“EAD is flexible enough to be used for a wide range of different finding-aids, from detailed inventories of the registers of the Kings of Poland 1447-1795, to catalogues of modern French planning permission files, which had originally been described in databases owned by the planning department.” (Amanda Hill)
