STRUCTURE
The regexp patterns follows the DefHash specification, and more specifically the structure
of Regexp::Pattern, defining access to one pattern per DefHash object, as "pat".
Additionally, (sub)patterns are available in plaintext form, as "pat.alt.*".
SUBJECT
Each pattern targets one or more subjects, i.e. ways to directly or indirectly represent a
license.
Beware that not all pattern objects fully cover all subjects.
trait
Distinguishing trait or feature expressed in licensing strings, e.g. an advertising
clause or granting "...or any later version."
Coverage for this subject is currently rather weak.
name
Distinguishing name, e.g. usable in license grant.
grant
Text granting the license.
license
Text containing licensing terms.
Texts containing both license grant and licensing terms (e.g. BSD- and MIT-style
licensing) may be classified as either subject grant or subject license. This may
change, as needs for distinction is better understood.
SCOPE
Each pattern can process material within some scope, i.e. a certain sample size of the
full subject.
As an example, <https://codesearch.debian.net/> use line-based processing, where patterns
spanning multiple lines are not applicable.
line
Pattern typically found within a single line. Typically this means less than 70
characters within scope.
sentence
Pattern matching within a sentence.
May span multiple lines, but not across multiple sentences. Typically this means no
full-stop or colon within scope.
paragraph
Pattern matching distinguishing paragraph.
May span multiple sentences, but not multiple paragraphs. Typically this means no
newline within scope.
section
Pattern matching distinguishing section.
May span multiple paragraphs, but not multiple sections. Typically this means blank
line within scope.
multisection
Pattern may span multiple sections.
OBSOLETE OBJECTS
License objects obsoleted by improved coverage of other objects, and provided only as
dummy objects.
• python
Since v3.9.0.
Replaced by "psf_2" and "python_2".
• wordnet_3
Since v3.9.0.
Replaced by "wordnet".
TAGS
Pattern defhashes optionally includes tags, which may help in selecting multiple related
patterns.
Tags are hierarchical, with ":" as separator, and may be extended without notice.
Therefore take care to permit sub-parts when tag-matching, e.g. using a regex like "
/\Asome:tag(?:\z|:)/ ".
• family:bsd
• family:cc
• family:gpl
• family:mit
• family:zlib
Pattern covers a license part of a family of licenses.
• license:contains:grant:*
License mentions a preferred form for granting the license.
This implies that license is commonly granted by use of a different (typically far
shorter) text.
Fourth part (optional) is the key to corresponding license pattern, for a grant
belonging to a different license (when omitted then a grant for same license is
assumed).
• license:contains:license:*
License contains another license.
Wildcard is the key to corresponding license pattern.
• license:contains:name:*
License mentions name of another license.
• license:includes:license:*
License references coverage of another license.
Wildcard is the key to corresponding license pattern.
• license:is:grant
License is commonly granted by stating the whole license.
• license:published:*
License grant may include an "as published by..." reference.
Third part is the key to corresponding trait pattern.
• type:trait:publisher:*
Pattern covers an "as published by ..." license grant phrase.
Third part (optional) is the key to corresponding license pattern.
• type:usage:*:*
Pattern covers a specific usage of a license.
Third part is the key of the corresponding non-usage-specific pattern.
Fourth part is the key of the corresponding usage trait pattern.
• type:combo
Pattern covers a combination of multiple licenses.
• type:group
Pattern covers either of multiple licenses.
• type:singleversion:*
Pattern covers a specific version of a license.
Third part is the key of the corresponding non-version-specific pattern.
• type:trait
Pattern covers a single trait occuring in licenses.
• type:unversioned
Pattern covers a license without versioning scheme.
• type:versioned:decimal
Pattern covers a license using decimal number versioning scheme.
EXAMPLES
Browse patterns
The "official" way to browse patterns is using App::RegexpPatternUtils:
show-regexp-pattern-module --page-result -- License
Unfortunately, App::RegexpPatternUtils has a deep dependency tree. An alternative is to
use Data::Printer and "less":
perl -CS -MRegexp::Pattern::License -MDDP -e 'p %Regexp::Pattern::License::RE, fulldump => 1, output => stdout' | less -RS
