1,3,5+ Application, Dialects, Architectures

Shlaer-Mellor modeling has always claimed to provide Platform Independent Models (PIMs) that can be translated with platform specific software architectures.  The theory is sound…, but tangible, touchable, downloadable examples can be hard to find. Several teams of engineers have successfully re-deployed applications onto different targets, and teams have reused their software architectures (model compilers) on

Papyrus Industry Consortium 2019

One Fact is a charter member of the Papyrus Industry Consortium. This organization involves many of those who are in the center of the modeling world.  The Papyrus IC was a gold sponsor at MODEL 2018 this year.  1F is looking forward to what is in store for 2019. https://www.polarsys.org/papyrus-ic/about

C Model Compiler Summer

The C model compiler has received new features this summer.   Here are some of the changes: Move to PyRSL version 2… way faster. keyed timers (now default) simulated time state save reflexive associative (loading) current state (changed before action body runs rather than after) poly to subtype (not supported so flagged as error) persistence of

Shinshu Class

In October, One Fact’s own Cortland Starrett will be teaching a 2-weeks long (all day each day) xtUML modeling course at Shinshu University in partnership with Takao Futagami and under the guidance of Professor Mizue Kayama. Look for the class syllabus coming soon.  

Super/Sub

…or Generalization and Specialization. In a modeled system, it is often important to categorize the entities in the system. Shown below a sedan and a sports car are both types of car each having a specialization. A convertible is a specialization of sports car.
