I'm finally getting around to updating our finding aid from the beta DTD to v.1, and indexing it using the files distributed at the LC site. I've used the Author/Editor rules file until now, so I hadn't really looked at the DTD until today. When I tried to index it using OpenText, I got a number of error messages, and discovered that the file eadbase.ent is missing the minimization indicators. As distributed, all of the elements in this file are formatted like this in "eadbase.ent": <!ELEMENT ead (eadheader, frontmatter?, archdesc) > whereas they should include the "-" or "O" to indicate whether the open and close tags are required or optional: <!ELEMENT ead - - (eadheader, frontmatter?, archdesc) > Once I added these indicators to all the elements, I was able to index my file. This seems to be a fairly serious error in the DTD--has anyone else pointed this out yet? Perry Willett Main Library Indiana University [log in to unmask]
