Re: curl License

Hi Julien,

From an SPDX License List matching standpoint (see: http://spdx.org/spdx-license-list/matching-guidelines ) the cURL license is indeed a cross between ICU (http://spdx.org/licenses/ICU.html) and ISC (http://spdx.org/licenses/ISC.html)
It has the same warranty and final clause re: advertising) of ICU, but the same grant clause of ISC.

According to the SPDX specification, one would then consider this as not on the SPDX License List and refer to it as per section 5 of the specification (LicenseRef-cURL, for example).

this makes me think it might be good to simply add cURL to the SPDX License List as it’s own entry to avoid such confusion. I’m copying this over to the SPDX legal mailing list, so that it will get raised as a topic there.

Thanks!

Hi,

I have found this email address in the commit log of the spdx-license

I would like to have your opinion about which license applies to cURL.

They use the X11 License [1] but not exactly because they changed the
following:

Except as contained in this notice, the name of the X Consortium shall
not be used in advertising or otherwise to promote the sale, use or
other dealings in this Software without prior written authorization from
the X Consortium.

by:

Except as contained in this notice, the name of a copyright holder shall
not be used in advertising or otherwise to promote the sale, use or
other dealings in this Software without prior written authorization of
the copyright holder.


Then it is closer to the ICU License. But that one explicitely has

License - ICU 1.8.1 and later

Copyright (c) 1995-2014 International Business Machines Corporation and
others
All rights reserved.

On top of it, which conflicts from the cURL license.


Are the Copyright headers not to be taken in consideration in this case?

Thanks
