This is an incremental update to the 2021-09 release. It corresponds to Eclipse plugin version 0.17.0.

Language features

  1. Derived and read-only features. In both KerML and SyML, the keywords derived and readonly can be used when declaring a feature/usage with metaproperty isDerived = true or isReadOnly = true, respectively.
  2. Package body elements. Removed the restriction in the SysML syntax on declaring flow connections directly at package level (i.e., not as the feature of a definition or usage).

Model Library

  1. HappensJustBefore. Added the association HappensJustBefore to the Kernel Library Occurrences model, to represent the relationship of one occurrence happening just before another, that is, when no occurrence exists that is after the first occurrence and before the second occurrence. (This is the "meet" relation in the Allen time interval formalism.)

Backward incompatibilities

  1. Keywords.
    • KerML: Added: derived readonly. Removed: id stream.
    • SysML: Added: binding derived readonly. Removed: id stream.
  2. Human IDs. In both KerML and SysML, the syntax for declaring a human ID has changed from idname to <name>.
  3. Flow connections. In both KerML and SysML, the keyword for flow connections has changed from stream to flow. The keyword for succession flow connections has changed from flow to succession flow.
  4. Binding connections. The SysML syntax for named binding connections has changed from bindnameassource=target; to bindingnamebindsource=target; The syntax for unnamed binding connections remains unchanged: bindsource=target;.
  5. Successions. The SysML syntax for unnamed successions has changed from successionsourcethentarget; to firstsourcethentarget;. The syntax for named successions remains unchanged: successionnamefirstsourcethentarget;

Jupyter

None.

Visualization

  1. Tom Sawyer
    • Revised visualization of human IDs.
  2. PlantUML

Bug Fixes

  1. Include use case usages. Fixed the implementation of effective names of include use case usages.
