Some GuidelinesGuidelines
GL1: The name of a subsystem consists of characters, digits, and _ ; it starts with a character …
GL2: The name of an Enable Block should be the same as the name of the related Enable Signal
GL3: Blocks may not possess unconnected Inports or unconnected Outports

• Needed model/document/artefact integration rule sets:
¾ create traceability links only
¾ check traceability link consistency, completeness, …
¾ remove inconsistent traceability links
¾ forward transformation
¾ backward transformation
¾ forward/backward attribute propagation

Traceability Link Definition
Traceability Link Definition
Basic Properties of Traceability Link Types:
• Permitted source and target classes in meta-models
¾ Simple consistency checks
• Multiplicities for both link ends
¾ Simple completeness checks
• Integrity constraints for link types (OCL, Java, … )
¾ Static correctness checks (static semantics)
• Structural integrity rules, …
¾ Automatic creation and checking of links
Additional properties of traceability link type definitions: • Inheritance hierarchies of link types
• Composition of rules for link types (subrules)
