Hello,

First thanks all for your good job.

I'm familiar with reqif, rmf and pror, but I still miss one point : the spec hierarchy

What kind of relational type a spec hierarchy is ?

Is it a refinement/derivation or more a composition ?

Feel free to add more background information if you think I'm out !

Thanks for help.

Anthony

Hello Anthony,

SpecHierarchy elements are arranged in a tree below a Specification. Each SpecHierarchy references a SpecObject. They allow the arrangement of requirements in a tree structure, and the SpecHierarchies are the nodes of the tree.

If you check out the ReqIF Spec (http://www.omg.org/spec/ReqIF/1.0.1/PDF/), this is visualized in Figure 10.6 (page 33).

I hope this helps!

Thanks Mickael,

But my question is more on the "what kind" of relation this spec hierarchy (the spec object node) address to the spec object leaf ?

Is it a refinement, a derivation, a composition, a copy... whatever else.

Thanks in advance.

Hello Anthony,

It's a reference, or, in UML-speak, it's a directed association relationship. You could probably also interpret it as an aggregation relationship, but that's not how it is represented in the spec.

Best,
