Wrong format for exceptions?

[tschmidtb51]

I was looking into the ABNF of SPDX and was wondering about the exceptions that are listed in the Scancode licensedb.

The ABNF states:

addition-expression = license-exception-id / addition-ref

with

license-exception-id = <short form license exception identifier from SPDX License List>
addition-ref = [%s"DocumentRef-"(idstring)":"]%s"AdditionRef-"(idstring)
idstring = 1*(ALPHA / DIGIT / "-" / "." )

This brings me to the conclusion that exceptions from Scancode's license DB should start with AdditionRef instead of LicenseRef. However, currently, they start with LicenseRef, e.g.:

• LicenseRef-scancode-apromore-exception-2.0
• LicenseRef-scancode-aptana-exception-3.0
• LicenseRef-scancode-bash-exception-gpl-2.0

Or is it intended to have the AdditionRef as prefix, e.g.

GPL-2.0-or-later WITH AdditionRef-LicenseRef-scancode-apromore-exception-2.0

in contrast to

GPL-2.0-or-later WITH AdditionRef-scancode-apromore-exception-2.0?

This is significant, and needs some design.

1. Be sure to save the old LicenseRef*exception name in other-urls.
2. check impact on license-expression library
3. check impact on DejaCode
