Bradley,

Your question sounds a lot like a question that I got answered in IRC  
yesterday.

The solution to my problem was to use the Fieldmapper.

Add the following lines to your Perl code near the top:

use OpenILS::Utils::Fieldmapper;
Fieldmapper->import("/openils/conf/fm_IDL.xml");

If you've installed Evergreen somewhere other than where the  
directions recommend, then you'll need to adjust the path in the  
import call above.

After doing the above any data returned from OpenSRF calls that use  
the Fieldmapper will be turned into objects that you can easily access  
from Perl. Use Data::Dumper before and after adding that code to see  
the difference that it makes.

In your subject, you say you are using the "gateway." If so, I'd  
assume you're writing your code in JavaScript. The above is easy to do  
from JavaScript as well. Dan Scott's workshop tutorial at

http://evergreen-ils.org/~denials/workshop.html

shows how to do this in the setion entitled "Accessing classes defined  
in the IDL via Fieldmapper." That subsection doesn't have a named  
anchor or I'd provide a URL directly to it.

Also worth reading is Dan's two part article at Code4Lib:
