relations with the same name

[magwas]

There are metamodels (e.g. Archimate), where are multiple relations in the same name.
Examples:

• All elements can be associated to each other: "Thing is associated with Thing"
• Product is associated with Value
• Business Object is associated with Meaning

Theoretically:

• These are different things, only the name collides.
• Sometimes there are more relations with the same name between the same relations.
• There is a short name for the relation ('associated with'), and a long one, containing the connected metamodel element names ('Product is associated with Value')

Features to be implemented:

• relation names:
  • in case of dashed relation names (e.g. 'composes/is composed of') short name uses the pre-dash part only (e.g. 'composes')
  • the long relation name
    • uses the pre-dash part for forward relations (Business Interface composes Business Role)
  • uses the passive form for backward relations (Business Role is composed of Business Interface, Business Interface is used by Business Role)
• In the palette:
  • There is only one entry for the same named relations
  • The short name is used
• In Magic Connector
  • All relations are listed for the endpoints
  • Long names are used
• When one relation is used from the palette
  • if there are more possible relations between the two elements with the same name, then a list with the long names are shown, and the user can choose the right one
  • if there is one possibility between the two elements
    • if the corresponding preference have its default value then we have the same menu with one entry.
    • if the preference is set, there is no menu, we just connect
