Zachary Turner has just finished work on his first tool for I2B, which is the "Dictionary Editor". This tool will help designers edit the class dictionary without risk of introducing typos. Another closely related tool is the "Prototypes Editor" is also underway. Both tools will be combined into a single executable to allow for easier cross referencing.
The reason these tools are being built at this time is that the programming group is already ahead of schedule, so putting more effort on tools would help the content group speed up their production.
