Batch Cataloging of Scanned Documents via OCR?

munwin99 asks: "I am looking for some software to process a batch of images (scanned forms). We want to use Gallery to view the images, and be able to search them by 3 or 4 attributes. We want to get these attributes from the form (date, name, etc). We want it to check a section of the scanned form, read the info from that section(s), and dump the retrieved info into Gallery (using OCR / ICR). Is there any (preferably) free or open source software that can do this? Supported OSes should include either Windows, Linux or Mac OS X. Even Gallery is optional, if someone has a better suggestion."
