Webel IT: Model-Based Systems Engineering and Software Engineering

  1. 4K: Narrated. Audience: Users of MagicDraw SysML or Cameo Systems Modeler who are experimenting with creating custom stereotypes that extend Block.

    This screencast video has been created to demonstrate some issues that can arise if you "naively" create a custom stereotype that extends Block without: (1) closing then re-opening your project; (2) creating an appropriate MD Customization. It is not about any actual "bug" in MagicDraw/Cameo (as long as you follow the recommended procedure). If you watch it, please do watch it to the end to find how to handle such stereotypes properly.

    Please note, this is not structured as a tutorial, it is an analysis screencast (but you can learn plenty from it). At 26 mins length it serves as an advanced follow-up reference for attendees of Webel IT training courses for MBSE with SysML.

    It is assumed that you have read the referenced MagicDraw help pages on Stereotypes and about creating your own Domain Specific Language (DSL) Customizations.

  2. 4K: Narrated. Audience: Users of MagicDraw SysML or Cameo Systems Modeler who are experimenting with creating custom stereotypes for SysML.

    This screencast video has been created to illustrate some pros and cons of using custom stereotypes in combination with Block inheritance and Part Property structures, and demonstrates some possible "gotchas". It concerns especially use of custom stereotypes to indicate: (1) cross-cutting aspects such as model layer membership; (2) use of tagged values to carry per-Element metadata.

    Please note, this is not structured as a tutorial, it is an analysis screencast (but you can learn plenty from it). At about 1 hr 35 mins length, it is not anticipated that viewers will watch this entire analysis video in a single sitting; it serves as an advanced follow-up reference for attendees of Webel IT training courses for MBSE with SysML.

    It is assumed that you have read the referenced MagicDraw help pages on Stereotypes and about creating your own Domain Specific Language (DSL) Customizations.

  3. This 4K narrated screencast video accompanies the white paper of the same name by Darren Kelly of Webel IT Australia available at: webel.com.au/omg/sysml/2019-11-18-Darren-Kelly-Webel-IT-Australia-proposal-LogicalWrapper.pdf

    The formal tool-independent part of the presentation is a 17:10 mins duration, followed by an informal exploration of some related aspects in the MagicDraw tool in an Appendix 12:32 mins duration (total duration 29:42 mins).

    Abstract

    The LogicalWrapper is a new graphical grouping element proposed for UML and SysML. The LogicalWrapper may not own elements that are not LogicalWrappers, it merely groups elements logically and graphically (visually) according to a logical context indicated by its name, with traceability of the logical members of the grouping. Any element that may be a logical member of a LogicalWrapper may be a member of more than one LogicalWrapper.

    The proposed symbol for the LogicalWrapper is a simple rectangle, with a name header similar to that of a Class symbol, a compartment for logical graphical grouping, and an optional listing compartment for logical members. A LogicalWrapper may be used in any UML or SysML diagram that supports element symbols that can be graphically contained within the proposed rectangular symbol for a LogicalWrapper.

    Graphical containment, in supporting diagrams, of wrapped symbols by the proposed rectangular symbol for a LogicalWrapper implies logical membership (grouping) of the elements represented by those symbols, but does not imply ownership or containment in any sense in the underlying model. A LogicalWrapper may itself be wrapped by another LogicalWrapper (nested) if the outer wrapper provides a relevant context for the inner wrapper.

    A proposed relationship Wraps can be used to indicate members of a wrapper when graphical containment is not used. Two LogicalWrappers may be related to each via binary relationships.

    Logical wrapping is presented as a parasitic organisational mechanism that is orthogonal to the “physical” ownership of elements afforded by Packages, Models, and other Namespaces.

    The LogicalWrapper shares some of the membership tracking powers of the SysML ElementGroup, and – like the SysML ElementGroup – it may be extended to help support elicitation of model elements through Graphical Parsing Analysis (although that is not its primary application).
