EAD Quality Control:

The RLG (Research Libraries Group) unveiled a new EAD quality control program in February 2006. The new quality control program is an update on their preexisting EAD Report Card.

The program itself is a complicated product, but it is extremely easy to use. If one has downloaded the automated program (a webbased version is available, but RLG reports that it is slower), all a user has to do to check his EAD's XML is use a Browse function, and, voila, errors are pointed out.
