Ha! Ethan beat me to it but here's mine anyway :) You're closing the c01 too soon. c02's have to be fully enclosed in c01's and the same rule applies all the way down -- c03s must be fully enclosed in their parent c02, etc. Your basic structure (a bunch of stuff removed to simplify) should look like this: <c01 level="series">Campus Expansion <c02 level="subseries">Rutledge Hall <c03 level="file">Anderson Electric Co. <c03 level="file">[other files] </c02> <c02 level="subseries">Some other hall <c03 level="file">[another file] <c03 level="file">[another file] </c02> </c01> Michele -----Original Message----- From: Encoded Archival Description List [mailto:[log in to unmask]] On Behalf Of Lauretta Scheller Sent: Thursday, May 13, 2010 2:30 PM To: [log in to unmask] Subject: Re: Help for newbie for C01, C02, C03 <dsc type="combined"> <head>Detailed Description/Box and Folder Listing</head> <c01 level="series"> <did> <unittitle>Campus Expansion </unittitle> <unitdate>1925-1952</unitdate> </did> </c01> <-- RIGHT HERE, THE C01 IS CLOSING TOO SOON <c02 level="subseries"> <did> <unittitle>Rutledge Hall, </unittitle> <unitdate>1937</unitdate> </did> </c02> <-- C01 SHOULD BE CLOSING HERE, AFTER THE C02(s) <c01 level="file"> <did> <container type="Box">1A</container> <container type="Folder">1</container> <unittitle>Anderson Electric Co. </unittitle> <unitdate>1939</unitdate> </did> </c01> Is this what you mean?

Could you post your c02 section? Alternatively, we've got several hundred EAD examples online here http://scrc.syr.edu/ead/xml which you're welcome to look at for examples.

I'm trying to set up a finding aid to indicate C01 as series, c02 as subseries, c03 as a file. Right now my one finding aid on-line has only c01 series and c01 file with box and folder. The collection I have now is rather large and will have subseries. What must I do to get xml to parse correctly? I keep getting an error for C02 Element content is invalid according to the DTD/Schema. Expecting: head, abstract, container, dao, daogrp, langmaterial, materialspec, note, origination, physdesc, physloc, repository, unitda... which refers back to <dsc>. I searched the listserv archives but did not find coding help. I'm pretty much alone without any IT help. I only know html. Lauretta Scheller, Archivist MacMurray College Jacksonville, IL 217-479-7694
