The file MD-pos.json contains heuristics to guess the POS annotation for MD entries. However, they may not be as precise as they can. e.j. yahaw and ahpô used to map to Part, while they could map to IPJ and IPC, respectively. I've made some candidate changes, but I believe a linguist should check (and perhaps extend) this set of mappings to get more precise info in the importjson.
