In the spirit of knowledge sharing and dissemination, the CERN Open
|
|
|
Hardware Licence (CERN OHL) governs the use, copying, modification and

|
|
distribution of hardware design documentation, and the manufacture and

distribution of products.

The CERN–OHL is to hardware what the General Public Licence (GPL) is
|
|
|
to software. It defines the conditions under which a licensee will be
|
|
|
able to use or modify the licensed material. The concept of ‘open-source
|
|
|
hardware’ or ‘open hardware’ is not yet as well known or widespread as
|
|
|
the free software or open-source software concept. However, it shares
|
|
|
the same principles: **anyone should be able to see the source (the
|
|
|
design documentation in case of hardware), study it, modify it and share
|
|
|
it.**
|
|
|
\>
|
|
|
\> In addition, if modifications are made and distributed, it must be
|
|
|
it.
|
|
|
|
|
|
In addition, if modifications are made and distributed, it must be
|
|
|
under the same licence conditions – this is the ‘persistent’ nature of
|
|
|
the licence, which ensures that the whole community will continue
|
|
|
benefiting from improvements, in the sense that everyone will in turn be
|
|
|
able to make modifications to these improvements.
