Me, too (hope so). However, not all of what they have makes sense to me. They have: Periodical Series - a sequential grouping of periodical issues - The New Yorker, Redbook, The Lancet, Amazing Spider-Man Periodical Issues - individual instances of periodicals - The New Yorker Vol. 1, Issue 4 Individual comic issues - short-form, saddle-stitched, serially published comics (the pamphlet-sized comics seen in comic book stores and hobby shops) - Amazing Spider-Man# 600 I'm fine with their "individual comic issue". In fact, when I look at the comics in my modest (mostly vintage) collection, they have all kinds of different series based on story arcs and sometimes no more than "1 of 2" so they definitely have numberings that aren't equivalent to journal numbering. Here's more from their page: Periodical Series (extends and inherits all fields from Intangible) endYear [number] the last year of publication of the series imprint [string] the publishing division which published the series startYear [number] the first year of publication of the series volume [string] the volume identifier for series Periodical Issue (extends and inherits all fields from Creative Work) issueNumber [number] the issue number within the series numberOfPages [number] the page count for the issue series [periodicalSeries] the series to which the issue belongs subtitle [string] the subtitle for the issue (e.g. "The Music Issue" or "The Anniversary Issue") upc [string] the UPC number of the issue numberOfPages [number] the number of pages in the issue Not very similar... but it's easy to see that having two very different proposals called "Periodical" could lead to confusion. And note that they were extending Intangible with Series - much like Dan's extention of Intangible with Issuance. So there's some sense to that, for some folks. But "imprint" in Intangible?! (Also note the repeat of numberOfPages, which already exists in /Book, and UPC, which I believe is covered in Product with gtin13 - 14 and 8.) > > (For that matter, I think Series, TVSeries and TVSeason also have > interesting characteristics that might be shared at some level with the > notions we are working with here.

In terms of "periodicity" broadcast provides at least as much complication as print materials. Note that schema.org/Series is defined as TV or radio series -- thus not usable for print materials. > (Plus, although we may not want > to go there, some A&I services include number of pages in their > metadata, which was used during the photocopy days of article ILL. > Presumably this can be inherited from CreativeWork.) > > > These are interesting questions.

Actually, I was wondering about the utility of: [sketchy example begins] Periodical name issuance volume number date vs. Periodical name volume number date I'm not getting the reason for the "issuance" as an intermediate level. So if anyone can illustrate why it's needed, that would help. Thanks, kc > > (Btw., I just realized I wrote Publication instead of Periodical in > quite a few places in my last mail.
