"I think it's useful to have a way to explicitly indicate the end of the list. Information on the Web may be lost or corrupted in all kinds of ways, so we can't always rely on the fact that missing information is significative." Although it may seem nice to be able to express there is no previousItem (start) or nextItem (end) I wonder if it actually will be used. Both HTML4 and 5 have those attributes as well but in all honesty I never encounter them. Rel="next/prev" sure but only because Google recommends it for pagination but there's no mention for using rel="start/last/end", and yet they do seem to be able to understand a series of documents. Now imagine the majority of webmasters don't use 'False' does that then mean parsers/reasoners don't understand where a list starts or ends? Somehow I doubt that. So personally I'm not convinced there's much to be gained by adding specifying a False, simply because I don't see webmasters/devs deploying it. 2014-09-12 19:17 GMT+02:00 Vicki Tardif Holland <vtardif@google.com>: > schema:False works for me. > > - Vicki > > Vicki Tardif Holland | Ontologist | vtardif@google.com > > > On Fri, Sep 12, 2014 at 1:12 PM, Martin Hepp <martin.hepp@unibw.de> wrote: > >> What about simply using schema:False, which exists?
