I’m glad to see the new expression syntax, including “+”, “with”, “and”, “or”, and “;”. Big improvement.
However, I suggest NOT requiring that expressions be surrounded with parentheses when there is no ambiguity (e.g., a single list of “and” or “or” at the top level). All the examples http://wiki.spdx.org/view/FileNoticeExamples include parentheses even in cases like “(GPL-2.0+ WITH Bison-Exception)”, which is more annoying for humans to type. By all means support parens, just make them optional in such cases. Thanks. --- David A.

This new syntax supports the ability to use a simple “+” operator after a license short identifier to indicate “or later version” (e.g. GPL-2.0+), and it also supports the ability to declare a standard license exception using the “WITH” operator (e.g. GPL-2.0+ WITH Autoconf-exception-2.0). SPDX has defined a list of standard License Exceptions to use after the “WITH” operator. A number of the standard License Exceptions were formerly included in the standard SPDX License List, but they have been deprecated as licenses, and correct usage employs the new license expression syntax. Note that for compatibility, the URL to each deprecated license still exists, but links to those deprecated licenses have been removed from the standard License List in order to clarify the currently recommended syntax. 2) license expression syntax FAQs (Mark) - please review: http://wiki.spdx.org/view/LicenseExpressionFAQ - for review and feedback 3) examples for license expression syntax on wiki page: http://wiki.spdx.org/view/FileNoticeExamples - for review and feedback Thanks, Jilayne & Paul SPDX Legal Team co-lead
