Abstract
In a computing device that receives handwritten data, a method and data structure that enables extended data to be added to an existing ink word data structure without compromising backwards-compatibility. A flag in the header data structure is indicates to new ink processing programs the presence or absence of the extended data, and the size information maintained in the header is adjusted ensure that earlier versions of ink programs do not lose the extended data. The extended data is then added by including it in a copy of the existing ink word data structure, along with a tail structure that includes information describing the extended data and the tail structure to the new ink code, e.g., version and offset information. The tail structure can be used to locate a list of alternate word choices for an ink word that are maintained within the extended data.
