If you have 3500 digital objects that belong to a collection, the collection itself should be a digital object, correct?  Does the Gerrit Smith collection have a unique identifier in your repository?  I would think that your repository software would enable one to query all child objects from a master collection object.  Fedora has REST APIs that enable this interaction.  If the Gerrit Smith collection has a unique identifier, you could use it as the id for the c02 or place it into altformavail, perhaps.  There are probably a few ways to go about it, but this would remove the need for placing URLs and query strings directly into your finding aid.  Software structure changes over time.  Certain APIs become deprecated (potentially making your query string nonfunctional), but unique identifiers in an institutional repository are intended to last for all time.

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.
