OSHWA (Open Source Hardware Association) is an organization that, among other things, has created and maintains a process to allow users and companies to certify that their projects are open source. Now, OSHWA has an API that allows you to submit projects much quicker and can make submitting large numbers of projects at the same time much easier and more straightforward.
