We need a way to export data in tab separated values from the marketplace catalog. This will allow for offline analysis in Applix, Excel, etc... This is a tracking bug...
The ability to do this is now present in the cms_pagemaker tool, and is included in the prototype version of the batch-mode marketplace update script. Direct access to executing this or to fetching the resultant data via browser has not been done, as the details are not finalized, and they would be out of the scope of this specific tracking ticket anyway.
