I'm not sure how it actually could be applied. I'd appreciate any help with this! I think http://www.productontology.org/ is not suitable in here. If you want to say that the game runs on a particular game platform, use Freebase or DBPedia or Wikipedia URIs for that single individual. http://www.productontology.org/ is for providing classes of things. Whenever you need an instance, either a particular object or an entitity that serves as a qualitative value (e.g. Diesel as a fuel type for a car, not as type of a product), Freebase or DBPedia are more appropriate. The only case where I see a use for http://www.productontology.org/ in this context is when you want to define the game platform entity in markup and want to provide more information on the type of the platform - e.g. a game runs on the ACME Gaming Cloud, and you want to say that this one is a http://www.productontology.org/id/Platform_as_a_service But I think those are edge cases. Also note that, without opening a big discussion, we may want to include "Thing" to the range of gamePlatform, since otherwise Webmaster will likely not understand that they can also point to entities defined elsewhere, not just URLs of Web sites.

And that'd fine if, as per your comment Jeff, those "associated properties to describe a game" include those currently proposed under RolePlayingGame. >>> >>> That is, the properties of the proposed RolePlayingGame type are (with the possible exception of quest) useful in describing video games of all sorts (especially min/maxNumberOfPlayer and statistic). These properties have equal utility whether they're included in the more general CreativeWork Game type that's been discussed, and so inherited by VideoGame, or whether they're included in the VideoGame type itself: I'd just be loathe to see these important video game properties disappear from schema.org proper in the course of finessing VideoGame. >>> >>> FWIW, in describing the type of a video game, I'd be far more likely to employ the now-available CreativeWork property genre rather than declare an specific game type described by a productontology.org URI, except in the case of declaring it a Product. >>> >>> I think another CreativeWork, Book, is a good example. >>> >>> An ebook is a type of book (in the physical sense), and is declared using the enumeration value EBook for the BookFormatType value of the bookFormat property of Book. >>> A novel is a genre of book, and would be probably be declared using the genre property of CreativeWork. >>> >>> A mobile video game is a type of game (in the physical sense), and might be declared either as more specific type of VideoGame, or using some sort of enumeration. >>> A role playing game is a genre of game, and would probably best be declared using the genre property of CreativeWork (or an enumeration like VideoGameGenre, which is what Freebase does (http://www.freebase.com/cvg/cvg_genre). >>> >>> This mostly in passing though: as long as core "game" properties currently contained in the RolePlayingGame proposal become available in schema.org, the needs of video game industry webmasters will be served IMO. :) >>> >>> >>> >>> On Fri, May 16, 2014 at 1:22 AM, martin.hepp@ebusiness-unibw.org <martin.hepp@ebusiness-unibw.org> wrote: >>> Hi Aaraon: >>> >>> On 15 May 2014, at 21:24, Aaron Bradley <aaranged@gmail.com> wrote: >>> > While I understand the rationale behind using productontology.org URIs I come down squarely against relying upon them in any situation where the class and/or properties in question are likely to be widely used by a large number of webmasters. I feel confident in saying that potential benefits of employing productontology.org URIs for something like the proposed platform property will ever remain potential because hardly anyone will employ it. schema.org's better-than-anticipated success has been predicated not only because it's easy to employ, but on the fact that it's self-contained. IMO, every time we punt to an external vocabulary we're shooting ourselves in the foot: I can't stress this enough (and I welcome Martin Hepp's input on this, both because I know he's had something to say about this recently in the context of his generic property/value pair proposal and, of course, because of his experience with productontology.org). >>> My point on mechanisms for externalizing or deferring consensus is as follows: >>> >>> 1. When there exists consensus in an external standard, it is better to refer to that standard than to incorporate it into schema.org - e.g. currency codes, GPC classes, most enumerations. >>> >>> 2.
