Hi Ralph -- No, you're not overusing it :) The <did> is required content for all c0# elements whether or not they have sub-c0# elements. (However, your example shows the c04 inside the <did> for the c03, which is not legal EAD tagging either.) Wrong: <c01> <c02> <did><unittitle>next level title</unittitle></did> </c02> </c01> Right: <c01> <did><unittitle>first level title</unittitle></did> <c02> <did><unittitle>next level title</unittitle></did> </c02> </c01> ----- Original Message ----- From: "Ralph Hartsock" <[log in to unmask]> To: <[log in to unmask]> Sent: Monday, January 16, 2006 3:58 PM Subject: Am I overusing the did ? > This is information from a collection of a composer. c01 is the > collection level; Series 1-4 are the next level, c02; each box is c03, > and individual documents are c04 or c05.
