Background
• 1988, 1991 Shlaer-Mellor Method published by Stephen Mellor and Sally Shlaer. • 2002 Executable UML established as Shlaer-Mellor OOA using UML notation. • 2004 Commercial Corporate Proprietary Licensed. • 2013 BridgePoint xtUML Editor goes open source under Apache 2.0. • 2014 all of BridgePoint (including Verifier and model compilers) goes open source under Apache and Creative Commons. • 2015 Papyrus Industry Consortium and xtUML/BridgePoint contribution • 2015 OSS of alternate generator engine (community building) • 2016 Papyrus-xtUML (BridgePoint) Eclipse Foundation governance • 2016 OSS contributions from industry, university and individuals

xtUML–ExecutableTranslatableUML
Unified Modeling Language − Industry standard notation − Family of languages
“Executable UML” − Defines a method, including:
• Semantics of diagrams • Relationship between diagrams • Execution rules • Order of construction • Path to implementation
DefectRemovalthroughExecu)on(interpre)veexecu)onofpar)almodels)
We find many defects through inspection, but…
…we find the rest by testing the system.
Executable models enable early and frequent testing.

■ Execute models before generating or writing any code — Run models immediately and incrementally — Remove defects early
xtUMLModelCompilersn Design patterns — Models of target — Templates
n Translation rules — Query — Transform (M2M) — Populate templates
n Marking — Like compiler flags — Determine which
patterns are applied to each model element • Build
