We intend to provide an open set of specifications, tools and services for generating verifiable badges that users can take with them wherever they go and use however they like.
For (a lot) more information, check out http://openbadges.org
- Webserver capable of serving requests to the general internet.
- Ability to make a POST request from your server backend and read a JSON response.
- Email addresses of the users you wish to issue badges.
- Badge image must be in PNG format.
- Generate an assertion (see below) for the user recieving the badge.
Store that assertion at a public-but-secret URL and serve it with
The assertion contains private information about a user, so you want a non-predictable URL scheme to prevent automated scraping.
This URL should be stable - any badge issued from it relies on its existence for verification.
Both of these problems will be solved in the near-term future by supporting signed assertions, so you'll only need to expose a URL containing your public key.
- Make a POST request to the open badge creator with the assertion URL. If
validation passes, you will receive an HTTP 200 with
content-type: image/png, the body being a your
badge.imagewith the assertion URL baked into it.
- Send/give the image to the user (for example, email it).
Please see the page on Assertions to learn how to format your assertions, and see the page on Badge Baking to learn more about how to use the baking API and what kind of responses to expect in case of error.
vagrant up in the project root will spin
up a fully provisioned VM (it'll take about two or three minutes, longer if
you don't have a
vagrant ssh to get into the VM, then
start-server will start up the server at
http://localhost:8888. The server will also watch for
changes, so you don't have to manually reload it.
openbadges/lib/environments/local.jsand edit the configuration to match your local development environment.
Setup your MySQL database. Create a database and a user with full privileges on that db
Install local dependencies:
Install global dependencies:
npm install -g up vows
Run the test suite:
Start your server:
up -w -p 8888 app.js
No matter which way you choose, you should join the Open Badges Google Group. If you have any problems setting up the environment, feel free to post a message to the list.
I like to be able to use http://openbadges.local for accessing the
project. Assuming you used vagrant, you can change the hostname in
sudo echo "126.96.36.199 openbadges.local" >> /etc/hosts to make it
happen. If you're on OS X, you can also use
Gas Mask for temporary hosts file switching
rather than having to manually edit /etc/hosts
