We present our work on web-deployed human interface for a knowledge grid intended for sharing medical knowledge. The grid allows medical specialists to provide their knowledge encapsulated as grid services, it allows the same or other medical specialists to easily locate the services, eventually build complex processing workflows from the services, and apply them to their data. Everything is done in secure manner, which is crucial in medicine.

The human interface has two parts - a web interface for so called documentation service and a web-deployed GUI interface for searching grid services and invoking grid workflows. As the grid connects experts from the whole world, a two-layered internationalization is an important feature.
