Constructs an AdditionRef (as a String) from individual ‘variable section’ Strings. Returns nil if addition-ref is blank, or the resulting value is not a valid AdditionRef.

Turns map m representing an AdditionRef into a String, returning nil if m is nil or the resulting value is not a valid AdditionRef.

Note:

• This fn is the inverse of string->addition-ref-map.

Is s (a String) a valid AdditionRef? See SPDX Annex B for specifics.

Canonicalises id (an SPDX license exception identifier), by returning it in its canonical case. Returns nil if id is nil or not a listed SPDX license exception identifier.

Is id (a String) deprecated? Also returns false if id is not in the SPDX license exception list.

See this SPDX FAQ item for details on what this means.

Are s1 and s2 (Strings) equivalent AdditionRefs (i.e. taking the SPDX case sensitivity rules in SPDX Annex B into account)?

Notes:

• Returns false if s1 or s2 are not valid AdditionRefs

Are id1 and id2 (Strings) equivalent SPDX license exception identifiers (i.e. taking the SPDX case sensitivity rules in SPDX Annex B into account)?

Notes:

• Returns false if id1 or id2 are not valid SPDX license exception identifiers

Are s1 and s2 (Strings) equivalent SPDX license exception identifiers or AdditionRefs (i.e. taking the SPDX case sensitivity rules in SPDX Annex B into account)?

Notes:

• Returns false if s1 or s2 are not listed SPDX license exception identifiers or valid AdditionRefs

Returns SPDX exception list information for id (a String) as a map, or nil if id is not a valid SPDX exception id.

opts are:

• :include-large-text-values? (default false) - controls whether the following large text values are included in the result: :comment :text :text-html :text-template

The set of all exception ids.

Initialises this namespace upon first call (and does nothing on subsequent calls), returning nil. Consumers of this namespace are not required to call this fn, as initialisation will occur implicitly anyway; it is provided to allow explicit control of the cost of initialisation to callers who need it.

Note: this method may have a substantial performance cost.

Is id (a String) one of the listed SPDX exception ids?

Returns the set of exception ids that identify current (non-deprecated) exceptions within the provided set of SPDX license exception ids (or all of them, if ids not provided).

Turns s (a String containing an AdditionRef) into a map representing that same AdditionRef. Returns nil if s is nil or not a valid AdditionRef.

Note:

• This fn is the inverse of addition-ref-map->string.

The version of the exception list (a String in major.minor format).

Note: identical to spdx.licenses/version.
