Initial Mediator

[LeonBein]

The different artifact modelers can share events via the mediator.

• OLCModeler: Olc state
  • rename,
  • creation,
  • and deletion (and undos) are captured,
  • deletions
  • and renames propagate to fragments (DO-references) and goal statement (literals)
• DataModeler: Data class
  • rename,
  • creation,
  • and deletion (and undos) are captured,
  • on deletion, data is appended for warnings,
  • additions propagate to OLCs (add new),
  • deletions and renames propagate to fragments (DO-references), OLCs, and goal state (literals)
• FragmentModeler: Data class creation (and undos) are captured
  Moved to Create Data Classes and States in the Fragment Modeler #66
• FragmentModeler: Olc state creation (and undos) are captured
  Moved to Create Data Classes and States in the Fragment Modeler #66
• (Optional) Deal with undos
  Moved to Handle Undos that affect multiple Artifacts #67
• pushed to develop

Undos to be discussed.
The problem here ist that, depending on what I did in other modelers, the undos become overly complicated.
E.g. what happens when I add/delete states in OLCs, then completely remodel the goal state and then do an undo in OLCs?
