Description

I would suggest that each source file containing copyrightable contributions start with a comment block to assert copyright and give a statement of copying permission.

For everything but the SDK, I'd suggest something like the following (replacing the list of years the actual years that copyrightable contributions were made to that specific file):

Copyright 2013, 2015, 2016 Curoverse, Inc.

For the SDK, I'd suggest something like the following (again, using actual years):

History

#1 Updated by Joshua Randall over 5 years ago

I should note that one reason I'm requesting this is that I've reached the point where future contributions from me will need to adhere to the Sanger Software Policy (https://github.com/wtsi-ic/wtsi-software-policy/releases/download/v7-20141218/wtsi-software-policy-v7-20141218.pdf) unless we arrange an exception.

Section 3.1.1 is particularly relevant:

If the existing source file contains no copyright notice, unless it is absolutely clear what the copyright
status is of the work, staff should assume it is actually copyrighted by someone and therefore it
should not be used as to do so would risk infringing that unknown copyright when the combined
work is distributed. 

I would find it awkward to have to add a Genome Research Ltd copyright to a file that was mostly authored by Curoverse but does not contain a Curoverse copyright statement.

In addition to the license and copyright, I'll need to add individual authorship records (see section 3.2) to the header comment block (i.e. identifying myself as an author). It therefore would be useful (but not necessarily required) if you also include authorship information for the exisiting code (perhaps a fall-back to something like "Curoverse Team" could be appropriate if curating the individual authorship of every source file is too cumbersome).

Assuming we would not do anything exceptional, if I were to make a copyrightable contribution to one of the existing source files after the suggested Curoverse initial comment blocks were added, it might end up looking like something like this:

Copyright 2013, 2015, 2016 Curoverse, Inc.
Copyright (C) 2016 Genome Research Ltd.

I'd feel slightly awkward about the "Authors" line if there was not some way to note that there were (likely numerous) other authors as well.

There are some tools out there to do this in a (semi) automatic fashion, see the list at https://wiki.opensource.org/bin/Main/Projects/List+of+Licensing+Tools/.

When doing this, make sure to add a message to the commit log that clarifies that this does not change the license status of any file, it just clarifies it on a per-file basis.

We should also consider using spdx instead of adding a full copyright header to each file, a la uboot (http://www.denx.de/wiki/U-Boot/Licensing).
