Hi Paolo,

Sorry, but I'm not clear what you are suggesting here?

I agree that the statement you refer to can be inferred from the other statements if they were reasoned over, and is redundant in that sense. Its purpose in the primer is to illustrate the use of the alternateOf relation. The reviewer has not understood the specialization and alternate relations, suggesting the primer needs to be clearer.

not sure who raised this, but I believe that in the example of 3.9 the statement

ex:articleV2 prov:alternateOf      ex:articleV1

is redundant, since it follows by Inf. 20 in CONSTR.

This may be noted explicitly but I would keep the statement, as it elicited a relevant comment.

It seems that whoever raised the issue feels, like me, that specializations and alternates should not mix so freely.

The figure makes clear the ambiguous interpretation of "alternateOf". Both V1 and V2 are different "specializations" of "article", yet they are declared to be alternates. I find this unintuitive.
