Exactly Doug, there's quiet a lot of work to do.
I'm co-leading a project around OB for the CPD of our teachers and trainers (agricultural education) in the field of education and technologies, so our work could feed this project.
We have already written our specifications (type of badges, validation process....). What we need now is to think beyond displaying" badges, and what kind of services to develop to make them useful within our ecosystem.
Currently we are using the Open bagde factory plugin that enables us to propose badges and badges claim forms without being dependent of one particular instance of Moodle.
