Compared to software, the open source approach is relatively new to most actors in the field of (mechanical) hardware.
Plus Open Source Hardware faces some special issues. A yet missing definition of its “source code” is one of them (+ patent law, liability, engineers that do not know how to work with git, costly prototyping…)
DIN SPEC 3105 will be/is the first official standard for Open Source Hardware and also the first official standard ever published under a free license (CC-BY-SA 4.0; that was a lot of lobby work 😉 ). It defines the technology-specific “source” of Open Source Hardware and aims to build a bridge between research institutes, public authority, industry and the worldwide open source community.
Here is a PDF of the slides: OSH Standardisation-36c3

Technology-specific Documentation Criteria (TsDC) specify the requirements for the technical documentation of Open Source Hardware (OSH). A TsDC is created (yet manually) by OSH projects/developers and is a subset of the TsDC database (TsDC-DB) provided in this repository. The concept of a TsDC was initially mentioned in DIN SPEC 3105-1 (since v0.3) and probably will be mainly used in this context.
