Thanks for the tip, that let me know it was possible.  I've gotten a little farther.  Now I have the following OpenSearch string:
 
http://dev.catalogue.nrcan.gc.ca/opac/extras/opensearch/1.1/-/rss2-full?searchTerms=rock+fissures&searchType=keyword&count=50&searchSort=create_date&searchSortDir=desc
 
searchSort=create_date, and searchSortDir=desc let me get the newest records.  However, I now need to figure out how to use searchTerms to return all records.  I've tried setting searchTerms to an empty string, and I've tried omitting it from the URL, but I'm not sure what sort of results that is returning.  As well, I do not get the same number of records when using OpenSearch that I get through the catalogue.  In the above search I get over 500 results from the catalogue.  However, I have requested 50 items through the count option in the URL, but I get less than 50 returned.  Is OpenSearch supposed to act like the catalogue, or am I trying to make it do things it wasn't designed to do?
