LetterData is an interactive environment for document generation. It allows an end user to select a template, enter the required data for the template and start generating the document. Once the document is generated, it can be edited using Microsoft Word or Open Office and enhanced with additional available text blocks. After it is saved, the document can be transferred to a manager for validation. Finally, the document can be transferred to post-processing services like emailing, printing or faxing.

The picture above is a sample of such a work flow:

1. The officer selects a template in LetterData
2. All mandatory data is entered using LetterData
3. An XML message is generated
4. LetterGen generates the requested documents
5. The documents are validated by the officer and transferred to his manager
6. The manager validates and signs the documents
7. The documents are processed by the distribution engine.
