AIAI is a collaborator on the Process Interchange Format (PIF) Project.
The PIF project aims to support translations such that process descriptions can be automatically translated back and forth between PIF and other process representations with as little loss of meaning as possible. If translation cannot be done fully automatically, the human efforts needed to assist the translation should be minimized. If a translator cannot translate part of a PIF process description to its target format, it should: (a) translate as much of the description as possible (and not, for example, simply issue an error message and give up); (b) represent any untranslatable parts so that the translator can add them back to the process description when it is translated back into PIF.
