.SH "STRUCTURE"
.IX Header "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 \f(CW\*(C`pat\*(C'\fR.
.PP
Additionally, (sub)patterns are available in plaintext form, as \f(CW\*(C`pat.alt.*\*(C'\fR.
.SS "\s-1SUBJECT\s0"
.IX Subsection "SUBJECT"
Each pattern targets one or more subjects,
i.e. ways to directly or indirectly represent a license.
.PP
Beware that not all pattern objects fully cover all subjects.
.IP "trait" 4
.IX Item "trait"
Distinguishing trait or feature expressed in licensing strings,
e.g. an advertising clause or granting \*(L"...or any later version.\*(R"
.Sp
Coverage for this subject is currently rather weak.
.IP "name" 4
.IX Item "name"
Distinguishing name, e.g. usable in license grant.
.IP "grant" 4
.IX Item "grant"
Text granting the license.
.IP "license" 4
.IX Item "license"
Text containing licensing terms.
.Sp
Texts containing both license grant and licensing terms
(e.g. \s-1BSD\-\s0 and MIT-style licensing)
may be classified as either subject grant or subject license.
This may change, as needs for distinction is better understood.
.SS "\s-1SCOPE\s0"
.IX Subsection "SCOPE"
Each pattern can process material within some scope,
i.e. a certain sample size of the full subject.
.PP
As an example, use line-based processing,
where patterns spanning multiple lines are not applicable.
.IP "line" 4
.IX Item "line"
Pattern typically found within a single line.
Typically this means less than 70 characters within scope.
.IP "sentence" 4
.IX Item "sentence"
Pattern matching within a sentence.
.Sp
May span multiple lines, but not across multiple sentences.
Typically this means no full-stop or colon within scope.
.IP "paragraph" 4
.IX Item "paragraph"
Pattern matching distinguishing paragraph.
.Sp
May span multiple sentences, but not multiple paragraphs.
Typically this means no newline within scope.
.IP "section" 4
.IX Item "section"
Pattern matching distinguishing section.
.Sp
May span multiple paragraphs, but not multiple sections.
Typically this means blank line within scope.
.IP "multisection" 4
.IX Item "multisection"
Pattern may span multiple sections.
.SS "\s-1OBSOLETE OBJECTS\s0"
.IX Subsection "OBSOLETE OBJECTS"
License objects obsoleted by improved coverage of other objects,
and provided only as dummy objects.

.SS "\s-1TAGS\s0"
.IX Subsection "TAGS"
Pattern defhashes optionally includes tags,
which may help in selecting multiple related patterns.
.PP
Tags are hierarchical,
with \f(CW\*(C`:\*(C'\fR as separator,
and may be extended without notice.
Therefore take care to permit sub-parts when tag-matching,
e.g. using a regex like \f(CW\*(C` /\eAsome:tag(?:\ez|:)/ \*(C'\fR.
