Vendors of certified equipment could then apply the program’s open hardware logo to their packaging and mention in advertising that their devices were certified. This meant making a set of promises about the availability of documentation for programming the device-driver interface of a specific hardware device. In 1997, Bruce Perens (creator of the Open Source Definition, and a co-founder of OSI, as well as a ham radio operator and enthusiast) launched the Open Hardware Certification Program to allow hardware manufacturers to self-certify their products as open. Of course, much of this early attention went to Open Source Software (OSS), though it’s important to note this is also when the first seeds of Open Source Hardware (OSHW) were planted.
