First, a point of clarification on ARUP (acceptable range of uniform practice), which is a phrase Daniel coined several months ago as Berkeley embarked on a couple of EAD union database projects. As I understand it, ARUP will make it much more feasible for finding aids from different repositories to reside harmoniously on a server, to be globally updated when necessary, and it should provide predictable results when searching across finding aids. Daniel is working on a set of ARUP guidelines for the American Heritage Virtual Archive Project (Berkeley, Duke, Stanford, and Virginia) and the University of California System Project, which I'm sure he'll make available as soon as it's ready. EAD was designed to privilege the intellectual organization of a finding aid (and, therefore, the collection) over the physical arrangement, because, as it has been explained to me, SGML doesn't handle two kinds of logic simultaneously very well. Therefore, if you use the <c0x> tags to code both the intellectual *and* physical arrangements, you are mixing the logics. The <c0x> elements have a level attribute to allow you to specify the *intellectual* level of the material you're describing in relation to the other levels present in the collection. There is no way to specify in <c0x> what boxes and folders represent (there is no label attribute, and the "file" attribute value does not mean "folder" in this instance). The <unitloc> element has a containertype attribute to indicate physical container (boxes and folders). The <dentry> and <drow> and <tspec> elements were created to support the tabular layout archivists frequently use for container lists. It's messy, I know, but until we figure out if the tabular layout can be generated completely by style sheets, necessary.
