Erm. I thought the agreed-upon pattern for using Role (first proposed by
danbri at
http://lists.w3.org/Archives/Public/public-vocabs/2014Sep/0009.html) would
be to apply the external vocabulary property in combination with
schema:contributor (e.g. lcrel:clr) and apply schema:roleName for those
consumers that might, for whatever reason, want to limit themselves to just
schema.org. E.g.:

<dl vocab="http://schema.org/" prefix="lcrel:
http://id.loc.gov/vocabulary/relators/">
  <span property="contributor" typeof="Role">
    <dt><span property="roleName">Pencils</span>:</dt>
    <dd><span property="contributor">Ron Lim</span></dd>
  </span>
  <span property="contributor" typeof="Role">
    <dt><meta property="roleName" content="colorist">Colors:</dt>
    <dd><span property="contributor lcrel:clr">Chris Sotomayor</span></dd>
    </span>
</dl>

... which generates something like:

    ns1:contributor [ a ns1:Role ;
            ns1:contributor "Ron Lim" ;
            ns1:roleName "Pencils" ],
        [ a ns1:Role ;
            lcrel:clr "Chris Sotomayor" ;
            ns1:contributor "Chris Sotomayor" ;
            ns1:roleName "colorist" ];

This was the direction I was taking things with my preconference at SWIB,
which even includes a Comic example:
https://coffeecode.net/swib14/preconference/rdfa_exercises/6_comic_book/

We could certainly update guidance and examples to use contributor types
from wikidata and other vocabularies, but I would like to ensure we're
starting from a common understanding. And having put a fair amount of
effort into the last iteration of Periodicals & Comics, I have some
interest in Comics going forward :)
