18-01-2012: Call for Comments on OHL v1.2

Subject: CERN OHL v.1.2


Thanks to all the feedback we have received on the CERN OHL v.1.1, we have made a few revisions and are now submitting the CERN OHL v.1.2 for comments and feedback (see text of the licence at The main changes were introduced in article 3 of the licence.
One point in particular is still under discussion and concerns article 3.3(e) – attempting to send modifications to the Licensors whose design was modified and those who requested it. On the one hand questions of practicalities arise – does every minor modification/debugging need to be sent to everyone? – while on the other it may be perceived as a fair return, for contributors, to be notified of modifications that were made. Your input and suggestions on this point are most welcome!

Another point which we would like also to consider is the question of compatibility with other licences.
David Mellis (of the Arduino team)had made the following suggestion:
"what about the possibility of aligning this license with the TAPR one, so that they could, for example, serve as localized versions of the same license? The licenses seem very similar in intent and approach (at least to a legally-naive reader) - it would be great if we didn't have to worry about choosing between them. At a minimum, maybe there's a way to allow for compatibility between them (i.e. the ability to combine TAPR OHL-licensed documentation with CERN OHL-licensed documentation)?

We hope to make the CERN OHL v.1.2 practical to use for anyone, so let us know if you think there are other points that could be improved as well.

Best regards,

11-01-2012: CERN's Director General cites OHL

Added by Erik van der Bij on 16 Jan 2012 at 09:31

In his New Year's presentation 2012 to all CERN's personnel, CERN Director General Rolf Heuer devoted one slide on the CERN Open Hardware Licence.
The slide reads:

Implementing new IP schemes
to bridge the gap between CERN and society

CERN Open Hardware Licence

A legal framework to facilitate knowledge exchange
across the electronic design community.
Version 1.1 of the Licence was issued in July 2011.

In the spirit of knowledge and technology dissemination,
the CERN OHL was created to govern the use, copying,
modification and distribution of hardware design documentation,
and the manufacture and distribution of products

Knowledge Transfer | Accelerating Innovation
