Should reversible arcs be included in new V2? #200

Closed adrienrougny closed 8 months ago

adrienrougny commented 6 years ago

For now, the reversible arcs are defined as production arc. Should we include a new arc as in oldV2?

Do you mean it would be reversible consumption arc with the arrowhead pointing to the source? For that we would need to know the "official" direction?

adrienrougny commented 6 years ago

Yes, in oldv2 it is a "consumption" reversible arc with the arrowhead pointing to the source. But I guess a "production" reversible arc with the arrowhead pointing to the target would work as well. This latter would maybe be more natural? In either case, I believe there would not be any "official" direction. Simply, nodes of the RHS are produced/consumed together, and it is the same for those of the LHS.

Editors' call 18/4/30: no new arc, but discuss reversible processes in the spec (in the process or the flux arc entry).
