The WANDAML markup language for digital document annotation

WANDAML is an XML-based markup language for the annotation and filter journaling of digital documents. It addresses in particular the needs of forensic handwriting data examination, by allowing experts to enter information about writer material (pen, paper), script and content, and to record chains of image filtering and feature extraction operations applied to the data. Annotations may be organized in a structure that reflects the document layout via a hierarchy of document regions. WANDAML lends itself to a variety of applications, including the annotation all kinds of handwriting documents (on-line or off-line), images of printed text, medical images, and satellite images.
