OHO Certification Center
- Until recently, there were no technical standards for Open Hardware.
- In 2020, we developed the world's first standard for Open Hardware together with the German Institute for Standardization (DIN) and other organizations.
- This standard uses a community-based peer review process that is often used for scientific publications.
- OHO is the first platform on which this procedure is applied.
- The aim of the Certification Center is to guarantee that projects published on OHO meet international quality criteria.
OHO Search Engine
- Many good Open Hardware Projects are unknown and difficult to find in the web.
- The multilingual OHO Search Engine aims to show as many projects as possible on a common platform.
- The Search Engine crawls the whole web and selects relevant search results according to different algorithms and categorizes them.
- The Search Engine has a keyword search, a professional search and a category search.
