As promised long ago on #code4lib, I've created a couple modules for dealing with MARC data in JSON; consider this a request for comments. - MARC::Record::JSON is a perl module that monkey-patches MARC::Record to provide a "as_json_record" method. This is essentially the same model used to ouput XML from MARC::Record, and has the advantage that you don't have to modify any existing code other than putting in an extra 'use MARC::Record::JSON; at the top of your file after 'use MARC::Record;'. - marcjson.js is a javascript library that make is not-too-awful to deal with the resulting data in javascript. The interface is modeled after MARC::Record in a very gross way, but has a stronger split between control and data fields. The MARC::Record::JSON data structure itself is *not* round-tripable (order of subfields within a field is not preserved), but makes for an easy-to-work-with format in read-only situations that one would probably be encountering within a web page. The whole thing, along with some documentation and a couple sample pages that show off the javascript library, is on Google Code. http://code.google.com/p/marc-json/ The samples of the JSON format at javascript code that pushes it around are at: http://code.google.com/p/marc-json/source/browse/trunk/samples/ Any -- and I do mean *any* -- comments would be much appreciated. -Bill- -- Bill Dueber Library Systems Programmer University of Michigan Library
