## Digitization and retro-conversion of printed or textual material is getting more and more important:

- Challenges

- Keep knowledge and cultural heritage alive
- Preserve the origin
- Enable quick and enhanced access by high structured documents
- Open up new dimensions of research
- Provide standardized output formats

## Automate the conversion process

- Goals

- Make digitization more effective and safer
- Increase the added value of digitized    collections
- Provide a standardized output format in order    to allow transformation of metadata into    various applications and systems
