Maybe I need an example, because I understood "issue" to be one of the properties of "issuance." So now I'm just confused ;-). > And I see nothing that would intuitively warrant that all issues of a > periodical are themselves collections of stuff.

I actually prefer to keep collection and periodical separate. In my librarian-ish (but not so precise as a cataloger's) mind, a collection is a finite group, and a periodical is, as the cataloging rules now call it, a "continuing resource." A periodical as conceived has no ending point -- it goes on as long as it goes on. A collection is a planned grouping with a beginning and an end. That said, some collections (the 7 volumes of Proust) weren't entirely spelled out from their first publication. We can, however, assume that even Proust knew that he wouldn't go on writing to infinity. (WEll, perhaps we can assume that -- he was a bit strange, after all.) kc > > Antoine > > >> >>> >>> As a matter of fact nothing prevents from having "Issuance" typed at a >>> higher level (CreativeWork or Intangible; this mail is not about that >>> part of the discussion!) and then let data publishers use an extra type >>> assertion to Collection (and statements with the "article" property) to >>> indicate when an issuance is a composite item. >>> >>> This would probably help making something that is less disruptive wrt >>> the existing Comics proposal. >>> >>> Best, >>> >>> Antoine >>> >>> >>>> I pulled together the various proposals we iterated over on the list >>>> at http://www.w3.org/community/schemabibex/wiki/Periodical - it has >>>> evolved somewhat as I started fleshing out the examples. >>>> >>>> I thought it would be far more efficient to have a reasonably complete >>>> proposal to look at and hopefully move forward on that relatively >>>> quickly. >>>> >>>> On Mon, Nov 18, 2013 at 10:28 AM, Karen Coyle <kcoyle@kcoyle.net> >>>> wrote: >>>>> Our next call is Thursday, 21st.
