I can't say that I'm a fan of including issue and volume in Periodical. Not only does it feel wrong, it seems like it's overloading Periodical with multiple meanings. I'd definitely prefer: Periodical > PeriodicalIssue > Article I have never really seen a compelling case for Volume (since it's kind of an abstract concept on its own), but Dan noted (off-list) that publishers will (sometimes) group on them (e.g. http://link.springer.com/journal/volumesAndIssues/11134#volume75, http://www.tandfonline.com/loi/wccq20?open=51&repitition=0#vol_51). I'm not sure I find this a particularly compelling use case, but if somebody can make a convincing argument that people actually use "volume" as a first class citizen, I don't know that I would put up too much of a fight against it (but I'd prefer it to be optional). I would *really* like to hear the opinion of some people in publishing on this. I feel like we're modeling their universe without any input from them, which is strange. The main reason I would like to keep "PeriodicalIssue" (or some equivalent) is to be able to align with Bibliontology (http://bibliontology.com/): Periodical would align pretty well with http://neologism.ecs.soton.ac.uk/bibo#Periodical; PeriodicalIssue to http://neologism.ecs.soton.ac.uk/bibo#Issue; and Article to http://neologism.ecs.soton.ac.uk/bibo#Document or http://neologism.ecs.soton.ac.uk/bibo#Article (I'd probably lean towards the more conservative superclass, but I don't have a strong opinion either way). Bibo only puts 'volume' on Document, which says to me that it was a compromise between books and serials and associated it with the Article, rather than the Issue, which probably doesn't apply to us unless there's commonality between Article and Book. -Ross.
