@pombredanne Can you please assign the ticket to me?

SPDX recently formalised this in spdx/spdx-spec#196

Though it's not formally released at the moment.

@carmenbianca 👍 thanks!

Might this be a duplicate of #1022? Or vice versa.

Any plans to enhance scancode towards reuse / SPDX-2.1 compatibility? We use reuse for a new OS project and it would be fantastic to use scancode. Currently this kind of headers are not detected:

Or

These are detected alright:

yield this with:
scancode -c --yaml -

@rainerth The SPDX-FileContributor is SPDX alright but seldom seen used in a file and not a reuse spec...It would be easy enough to add this as an "author" tag in ScanCode ... I can see enough instances of it in the wild to add it

So I pushed this #2838
and now we get this:

 * SPDX-FileCopyrightText: 2008 Red Hat Inc.
 * SPDX-FileContributor: Adam Jackson <ajax@redhat.com>
 * SPDX-FileContributor: Bill Nottingham <notting@redhat.com>
 * SPDX-FileContributor: Ray Strode <rstrode@redhat.com>
