Hi all,

short update from my side, as thinking about this topic.

I recommend:

A) Using Full Header as GNU Recommended

or

B) Using SPDX-License Header.
This is new in Open Source and maybe will make its way.
Frederik did already some research with that and we can scan complete
projects of licenses conflict. That is pretty awesome and may help us in
the future.

BUT don't invent something by our own.

About the Authorship. I see several way, so some marks:

- Their should be at least one author or Organization
- the inital module/file create is a commend option
- the current maintainer can added as well
- i prefer to collect 'contributor' collect to __openerp__ to make
header not to big (for every patch adder)
- we just can add in each header "OCA + Year" as Author as the CLA
allows to republish as the name of OCA and the human author is in
__openerp__

Hope this helps to get the discussion forward.

Kind Regards

Markus
