Badge System Design: what we talk about when we talk about validity
The question of validity is posed fairly commonly.* It goes something like this, “How can we ensure that the badges have a sense of validity?” or “Who will vet them?” or “How will we know that they’re worthwhile badges issued from reputable sources?”
Validity
Validity addresses the question of representational accuracy: does something perfectly represent the thing it’s allegedly designed to represent?
Credibility
Credibility inspires belief and is derived from perceptions of trustworthiness and expertise. These things can be assessed through personal means but quite often are accepted tacitly.
Reliability
Reliability might be considered the replicability quotient of an event, idea, performance, etc. Something that can be consistently measured is considered reliable.

Identifying individuals by email address
I have a question. When looking at the instructions for getting a Mozilla Backpack, I was instructed to make sure to use the same email address that I used to register on Coursesites. I'll be able to easily check which of my several email addresses i used, but my first worry was that I could end up with several identities in openbadges.org - I suppose you could add email addresses to an identity, but that does not seem to be available. Has this issue been discussed?

Sistema en PHP
After working on designing and implementing a system that *could* be used within universities, or similar, I've developed the application to a point where it is probably time to share it.
I wrote a blog post the other day : http://coursedata.blogs. lincoln.ac.uk/2012/05/23/ release-the-badges/ 'announcing' the system, the code for which is available on Github https://github.com/lncd/Badges . A previous blog post loosely describing the design process can be found here: http://coursedata.blogs. lincoln.ac.uk/2012/04/25/ designing-an-badge-system-for- universities/
As I discuss in the blog post, its by no means a finished product, but I will continue to work on it, fixing and adding elements to it. The code itself is by no means perfect, as the scope of the application has changed that many times through the development cycle that the code has got, at best, a little bit messy. I've already had a quick review of one of the model files, removing pointless functions and replace multiple similar functions with one function that serves all of the requirements. I'll continue to do this until the code is at a decent standard, but this particular implementation is meant as nothing more than a prototype with which to trial the process and concept of awarding badges.
As I'm writing this, the documentation on Github is a little sparse, but it is my intention to work on the documentation over the next day or so to get it to a reasonable level.
I think that we may trial the application on a small scale around September, although we're yet to decide how best to trial it. Comments welcome.
