WatchOCR
What WatchOCR is
WatchOCR is a free OCR server that converts image-only PDFs and TIFFs into text-searchable PDFs. It supports Linux and web access, with files processed either by monitoring configured folders for new scans or by uploading individual files through the web interface. Its barcode feature can rename files and arrange them into directories based on barcode information. WatchOCR uses the Cuneiform and ExactImage OCR engines. The project offers a preconfigured LiveCD and Ubuntu .deb packages. The download page labels v0.8 an early beta that may have major bugs, and the LiveCD uses Knoppix 6.4.4. Listed Ubuntu packages are v0.7.2; the web interface package is optional for remote administration. Installing the .deb packages requires the Ubuntu lucid partner repository because sun-java6-jdk is not in the default repositories. The LiveCD provides a network shared folder that workstations can map using Windows Explorer. Configured folder paths must be readable and writable by the www-data user. The site says the software is generally under the GNU General Public License, subject to its stated license terms.
