An Ordinary of Arms is a listing of blazons ordered by the charges. This permits one to take the image of a shield and work backwards to find the person to whom it was registered. There are a few examples to draw from, but they often contradict themselves, much less each other, about the proper way to structure such. As a consequence, in addition to the not insubstantial clerical task involved, this will also require the construction of a strict grammar for blazons; one that may be rather more strict that would be required for registration.
