Open-source toolkit for simple XML annotation.

Use of Extensible Markup Language (XML) is increasingly prevalent among medical informatics projects. Many of these projects involve, at some point, the interaction between a researcher and specialized XML documents for the purpose of annotating the XML data. We offer a simple toolkit to assist these researchers. Our solution is a simple, yet fully functional, annotation system that can easily be adapted to the needs of the researcher. All of the materials for this toolkit are freely available.
