bnlviewer

The National library of Luxembourg's viewer for METS (http://www.loc.gov/standards/mets/) files with OCR files in the ALTO format. The viewer needs a tomcat application server to run in. It can be deployed so that it reads the METS files from a local folder. Its main use is for digitized newspapers and postcards but can be adapted to other METS profiles as well. The viewer can be seen in action at: http://www.eluxemburgensia.lu
