TL;DR: A year ago, I said I wanted to build a badging service for the Mozilla community, so we could all celebrate how awesome we all are. Well, I putzed around and didn't get far, so I'm starting over with something more immediately useful.
(This is an awesome illustration by Sean Martell, used entirely without permission. I'll take it down if anyone gets mad.)
Almost a year ago, I wrote about building a badging service for all of Mozilla.
In a nutshell, I left the 2010 Mozilla Summit wanting to build a tool that empowered people to craft social objects representing achievement and gratitude, and give them to each other.
Since then, I've played around with a prototype in Django with Pinax. But, I abandoned that thing due to getting super busy with the Firefox 4 release. It also didn't help that I was a Django newb and that I got caught up in screwing around with shiny things like Pinax and Lettuce and neglected the actual feature set.
So now, finally, I'm picking the thread back up again. This time, with a little less ambition and a few more practical aims.
Make something more useful right away
While I have spent some dangerous time screwing around with shinies like Vagrant, Puppet, and Playdoh, I think I've gotten that mostly out of my system and have gotten down to work as of last night.
Rather than build a Grand Central Station for badges, I've reset my goals to a progression of practical results:
- Build a reusable Django app that supports some basic use cases of creating and awarding badges to users.
- Add Activity Streams narrating badge claims
- Add support for PubSubHubbub with Badger activity streams
- Add a REST API, maybe with OAuth
- Accept badges for local users, via PuSH from external sites
- See what the Open Badges Project is up to, and how Badger can fit in with their goals.
The idea here is to make Badger a practical, reusable, drop-in app for existing sites—preferably (but not necessarily) the Playdoh-flavored sites we're building at Mozilla. Then, incrementally and optionally empower a Badger-enabled site to become a badge hub by accepting reports of badge claims from other Badger-enabled sites.
Take baby steps to federation
So, for example, let's say we dropped Badger into a few sites like these:
At first, Badger would just augment those sites with badging facilities for their respective user bases. That could fill some needs right away.
Then, say we built a site that offered personal profiles to members of the Mozilla community. With the Activity Stream and PuSH augmentations, users could connect their profiles with each of the other Mozilla sites they use. That way, whenever they claim a badge out there, it gets delivered to their community profile.
Why bother federating at all?
If the only cross-site goal to build an all-in-one display case for badges on a community profile, I could just build JSON feeds and wrap them in a JS-based widget. In fact, a JSON-formatted Activity Stream will work nicely for that. Drop that into the profile page, and we're done.
There are lots of reasons to federate. But, at least one thing not supported by this solution are meta-badges. That is, badges awarded for badges.
Let's say you close 100 bugs on Bugzilla, answer 100 questions on SUMO, edit 100 pages of documentation on MDN, and author 100 add-ons. And, let's say you get badges on the respective sites for all of those activities.
Well, now, I'd like to give you a badge on your community profile for being a Mozilla Superhero. I could just do that by hand, having observed all your greatness. But, I'd rather the system just do that automatically.
If your community profile treated all your badges from your chosen affiliated sites as first-class citizens, then I could build the meta-badge trigger right there.
Of course, I could also write a program that monitors badge feeds from various sites. Then, use the community profile site's Badger API to issue a badge when the conditions are met. But, as maintainer of the monitoring program, I'd have to keep track of what feeds where count for which people, which could be a mess.
There's still some thinking to do here.
What about identity and co-opting badges?
I'm still thinking through how someone connects a profile to other sites. As in, how can Badger ensure that the owner of the community profile is also the owner of a badge claim feed on MDN? Maybe some kind of OAuth dance that results in a PuSH subscription between sites?
Consider the least-capable federation case: a Badger-compatible feed hosted as a static file on Amazon S3. And, by Badger-compatible, I mean an Activity Stream that contains badge claims. You shouldn't need my specific implementation of Badger-in-Django to produce one of those.
Although PuSH is still the ideal case (I think), occasional polling of an Activity Stream feed should still be supported. If a user connects that up to their community profile, we just have to take their word for it. We'd rely on community members to flag stinkers trying to claim badge feeds that aren't theirs.
Beyond that, there's probably some crypto-voodoo we can invoke here, for cases where badge claim validity really matters—as opposed to the fun and games I have in mind for Mozilla.
What about the Open Badges Project?
From various conversations over the past year, it sounds to me like the Open Badges Project is getting the parts in place to do even more interesting federation of badges that gives ownership of the badge hub to the user.
In that scenario, you have a backpack in your browser and can carry your badge claims with you between sites with no prior coordination between the sites themselves.
This sounds like something in which Badger should be able to participate, eventually. If not as a hub, Badger should at least offer the tools to create and award badges that work with the user-owned hub scheme.
So, what next?
Now that I've written all this out, I need to hack on it. If you're interested in this stuff, let me know. That way, it'll look like someone might actually find this stuff handy when I get something working!
