Hello Community! I have a quick question over the mappings from SysML v1.6 to SysML v2.0 concepts. Currently, I’m doing a Master thesis on transition between versions, and for this I’m using a mapping file called ‘Part 2: SysML v1 to SysML v2 Transformation’. For me to transform the concepts, I extracted some features from the selected bdd’s models that are to be transformed. As far as I can see, the mappings are:  
Block → PartDefinition  
Enumeration → EnumerationDefinition  
EnumerationLiteral → EnumerationUsage  
Operation → PerformActionUsage  
Interface → PortDefinition  
Generalization Relationship → Subclassification  
Realization Relationship → Dependency  
Composition Relationship → ?  
Aggregation Relationship → ?  
Association Relationship → ?  
As you can see, I’m bit lost with the latter 3 relationships and can’t find direct mappings for these concepts. Does anyone perhaps know how to deal with it? Any help would be highly appreciated. Thanks in advance! 🙂

P.S.  
Originally I wanted to post a link to the file, but it seems that the words ‘o m g’ or ‘O M G’ are not allowed to be posted, even in the context of a company (lol). Seems a bit weird.

Totally agree - that should not be a problem anymore. Thanks for making this note:)
