Suppose that you have a collection of 3500 items that has been completely digitized. Suppose that you do not wish to have 3500 <dao>'s in your EAD finding aid, but instead would prefer to provide a link that would fire off a search of your digital image system and retrieve all relevant items for each particular series or subseries, Suppose, finally, that you do not wish to hard code a full URL of "http://very-very-very-long-string" but rather want to encode just the relevant search terms and let the style sheet construct the link. Presumably you would still use <dao> for this, since these are digital versions of archival material in the collection. But what attribute(s) of the <dao> would you use to encode the search terms? For example, let's say this dao is intended to fire off a search of a digital collection called "Gerrit Smith" and bring up all the correspondence from 1850-1860. Would this be a correct encoding, with the two search parameters in the href? <c02> <did> <unittitle>Correspondence></unittitle> <unitdate normal="1850/1860">1850-1860</unitdate> <dao linktype="simple" role="http://digilib.syr.edu/Gerrit_Smith" href="type:correspondence;date:1850-1860" actuate="onrequest" show="new"/> </did> </c02> Also, if anyone has working examples of something like this please share.
