Issue 15729: SysML Issue based on UML 14062 -- Stereotypes/keywords and upper/lowercase (sysml-rtf)
Source: Lockheed Martin (Mr. Michael Jesse Chonoles, michael_chonoles2(at)omg.org)
Nature: Uncategorized Issue
Severity: 
Summary: UML issue 14062 now attempts (though is not completely successful) in begin Stereotypes with uppercase and keywords with lowercase, though the old stuff will still work. Effectively, this is a style recommendation for the specification and for later methodologist.  

 

SysML should probably for sake of consistency adopt this as a guideline for our spec and developers

Discussion: 
In the UML 2.4 Superstructure specification, under the subsection "Notation" in
Section 18.3.9, Stereotype (from Profiles), the following statement appears:
Normally a stereotype's name and the name of its applications start with
upper-case letters, to follow the convention for naming classes. Domainspecific
profiles may use different conventions. Matching between the
names of stereotype definitions and applications is case-insensitive, so
naming stereotype applications with lower-case letters where the
stereotypes are defined using upper-case letters is valid, although
stylistically obsolete.
SysML consistently follows the lower-case keyword convention for stereotype
applications, which the UML specifications now indicates is a valid convention for
domain-specific profiles. The less-obtrusive lowercase keywords are valid
according to the case-insenstive matching of stereotype names, and is preferred
by many users based on long-standing practice in SysML and because the many
uses of such keywords in SysML are less obtrusive than uppercase names would
be. Language could be added to the SysML specification to explain this
capitalization convention, however. The issue is being deferred so that a more
explicit statement of these conventions can be considered in a future revision of
SysML.
