One of the things I have discovered as I work with badges is that they are not all the same. The badges issued to staff are qualitatively different to those offered to students. Many of the badges incorporated into learning management tools are different again. This is problematic, because if badges representing robust credentials are put beside ‘well done’ badges issued to grade school students, the integrity of the whole system is put into question. To overcome this a standard taxonomy for badges needs to be established to differentiate between types of badges within the open standard. The question is how should this taxonomy be defined?
