Added SPDX license codes to all formula files

[suleman-uzair]

Adds a new spdx_license field to all formula files using official SPDX identifiers or LicenseRef- custom encoding for non-standard licenses.

closes #240

[ronaldtse]

@suleman-uzair I've done some investigation and some license codes are incorrect. I've fixed the fonts f1.8 and joongnajoche because they are actually OFL (fixed in v4 already)

The available licenses are here:

• https://github.com/search?q=repo%3Aspdx%2Flicense-list-XML%20font&type=code

Some of the assignments are more nuanced:

• OFL has a variant called "Reserved Font Name", e.g. Formulas/carlito.yml:

license_url: http://scripts.sil.org/OFL
open_license: |-
  Copyright (c) 2010-2013 by tyPoland Lukasz Dziedzic with Reserved Font Name "Carlito".

  This Font Software is licensed under the SIL Open Font License,
  Version 1.1 as shown below.

The SPDX code is OFL-1.1-RFN, not OFL-1.1:

• https://github.com/spdx/license-list-XML/blob/1ff5448a90588c9b173ca45f388125937812aa36/src/OFL-1.1-RFN.xml#L3

There seem to be 3 variants of OFL:

• OFL
• OFL RFN
• OFL No-RFN

OFL seems to be the only one to be fixed.

Then we have the proprietary licenses. According to spdx/license-list-XML#1856 we can encode them like LicenseRef-{company}-{some-id}.

• Apple licensed fonts. I found two licenses;

  • Formulas/lucida_grande.yml: "SOFTWARE LICENSE AGREEMENT FOR SAFARI FOR WINDOWS". We can use LicenseRef-Apple-EA0473 (this is the Apple License ID given at the end of the license).
  • All the fonts under Formulas/macos (e.g. Formulas/macos/headlinea.yml): "For use on Apple-branded Systems". We can use LicenseRef-Apple-EA1705
  • I only found these two "EA" numbers.

• Microsoft:

  • "TrueType core fonts for the Web EULA": use LicenseRef-Microsoft-fontpack-19980728
  • "MICROSOFT OFFICE 2013 DESKTOP": LicenseRef-Microsoft-Office2013-1
  • "MICROSOFT OFFICE 2013 DESKTOP APPLICATION SOFTWARE": LicenseRef-Microsoft-Office2013-2
  • "MICROSOFT POWERPOINT VIEWER" (internal ID: EULAID:O14_RTM_PPV.1_RTM_EN): LicenseRef-Microsoft-PowerpointViewer
  • "Microsoft Viewer for Word": LicenseRef-Microsoft-WordViewer
  • "MICROSOFT OFFICE EXCEL VIEWER": LicenseRef-Microsoft-ExcelViewer
  • "MICROSOFT OFFICE FOR MAC": LicenseRef-Microsoft-OfficeMac
  • "SUPPLEMENTAL END USER LICENSE AGREEMENT" "GB18030 support package for MICROSOFT WINDOWS Operating Systems": LicenseRef-Microsoft-GB18030
  • "Windows XP Font Pack for ISO 10646:2003 + Amendment 1 Traditional Chinese Support": LicenseRef-Microsoft-ISO10464
  • "MICROSOFT SOFTWARE LICENSE TERMS" "MICROSOFT EAST ASIAN FONTS OPTIMIZED FOR CLEARTYPE": LicenseRef-Microsoft-EastAsianClearType

• Adobe:

  • "Adobe End-User License Agreement": LicenseRef-Adobe-EULA

We just need a code for each of these.

Needs Review

• LicenseRef-Microsoft-ISO10464 — The EULA references "ISO 10646" but the identifier was set as ISO10464. Should this be corrected to LicenseRef-Microsoft-ISO10646?

• LicenseRef-Microsoft-Office2013-1 — All 6 Language Pack files use the same EULA containing both Retail and OEM terms. Unsure how to distinguish between Office2013-1 and Office2013-2. Currently all set
  to -1.

• MIT OR OFL-1.1-no-RFN — monoid is "dual licensed with MIT and OFL licenses. Pick one :)" No RFN clause found. Should this be MIT OR OFL-1.1-no-RFN or just one of them?

• LicenseRef-au-passata — "Passata requires no licences" alongside "All rights reserved". Would appreciate guidance on the right encoding.

[ronaldtse]

@suleman-uzair there are a few errors.

OFL RFN assignment

Most of the RFN assignments are wrong.

Regarding OFL RFN:

Just because the license contains "Reserved Font Name" does not mean the license is RFN.

For example:

• Formulas/kurobara-cinderella.yml is not RFN, i.e. this statement is NOT RFN:

  • "Reserved Font Name" refers to any names specified as such after the copyright statement(s).

• Formulas/lato.yml , Formulas/selawik.yml are RFN (the statement is in Copyright)

  • description: 'Copyright (c) 2011-2020 by tyPoland Lukasz Dziedzic (http://www.typoland.com/) with Reserved Font Name "Lato". Licensed under the SIL Open Font License, Version 1.1 (http://scripts.sil.org/OFL). '

• Formulas/courier_prime_code.yml are RFN (the statement is this in the license):

  • 3. No Modified Version of the Font Software may use the Reserved Font Name(s) unless explicit written permission is granted by the corresponding Copyright Holder. This restriction only applies to the primary font name as presented to the users.

ming_uni

ming_uni — copyright DynaComware Corp, licensed by HK SAR Government

The original license is correct as stated in Formulas/ming_uni.yml. This license was the original license and is no longer available from the website. Rename this LicenseRef-HKSARG-SoftwareTOS.

gwm_sans_*

LicenseRef-gwm-sans	5	Based on SIL OFL but with Great Wall Motors proprietary modifications — not pure OFL

Incorrect. This is a translated "SIL OFL 1.1 with RFN" with a vendor-specific preface (which is common practice when adopting OFL). So it is just SIL OFL 1.1 with RFN.

Additional license

I also found this:

  MICROSOFT SOFTWARE SUPPLEMENTAL LICENSE TERMS

  FONT SETUP PACKAGES FOR MICROSOFT OFFICE 2010 AND 2013

In:

• Formulas/dengxian.yml
• Formulas/yu.yml

Need a new license for this?

Answers to the questions

LicenseRef-Microsoft-ISO10464 — The EULA references "ISO 10646" but the identifier was set as ISO10464. Should this be corrected to LicenseRef-Microsoft-ISO10646?

Yes, 10646 not 10464.

LicenseRef-Microsoft-Office2013-1 — All 6 Language Pack files use the same EULA containing both Retail and OEM terms. Unsure how to distinguish between Office2013-1 and Office2013-2. Currently all set
to -1.

All 6 use the same license. There is a separate license I mentioned above.

MIT OR OFL-1.1-no-RFN — monoid is "dual licensed with MIT and OFL licenses. Pick one :)" No RFN clause found. Should this be MIT OR OFL-1.1-no-RFN or just one of them?

We need to represent that a font can have multiple licenses.

LicenseRef-au-passata — "Passata requires no licences" alongside "All rights reserved". Would appreciate guidance on the right encoding.

Use LicenseRef-AarhusUniversity-Passata as the license. The license is just that: Passata requires no licences. Note that we only deal with "Font Licenses". Copyright and "rights" are a completely separately subject that is irrelevant.

Relationships between licenses

There are a few notable issues here uncovered:

• some fonts are/can be multi-licensed. We should reflect that.
• some vendors make modifications on licenses that may or may not be semantically relevant
• we need to have a way to tell what features a license provides: can we subset/superset/convert/re-package/embed in documents/embed in software etc.

We need to basically define a schema for a license, and then have a register of these licenses, e.g. fontist/licenses and we can reference them properly.

For now, we can just fix the issues and then have the license relationship as a separate enhancement.

@suleman-uzair @HassanAkbar please merge when ready. Thanks! Let's make this a feature of Fontist Formula v5.

[ronaldtse]

@HassanAkbar @suleman-uzair Maybe we should merge this into #222 directly?

@HassanAkbar @suleman-uzair Maybe we should merge this into #222 directly?

@ronaldtse sure, I’ll retarget this PR to the branch used by #222 and merge it there.
