Hi,
At this point I can’t really tell whether it’s a bug but I guess it’s at least worth opening an issue in case it can be clarified and labeled properly for people in the future in case it’s a wontfix.
So I’m referring to the “meta properties” section of EPUB Packages 3.2.
So let’s start with zero or more cardinality. Obviously, people are aware of alternate-script e.g.
<dc:creator id="creator1">Jane Doe</dc:creator>
<meta property="alternate-script" refines="#creator1" xml:lang="ja">山田花子</meta>
<meta property="alternate-script" refines="#creator1" xml:lang="ar">فُلانة الفُلانيّة</meta>
Which is obviously fine.
But then I have a doubt with zero or one cardinality, as EPUBCheck doesn’t report anything for:
<dc:creator id="creator1">Jane Doe</dc:creator>
<meta property="role" refines="#creator1" scheme="marc:relators">aut</meta>
<meta property="role" refines="#creator1" scheme="marc:relators">edt</meta>
nor:
<dc:title id="t1">Title of the book</dc:title>
<meta property="title-type" refines="#t1">main</meta>
<meta property="title-type" refines="#t1">subtitle</meta>
Is this a bug, is this the spec? I honestly can’t tell at this point – and we have a hard time finding a common interpretation amongst a group of people, hence why I prefer to open this issue too.
Mind you, it would not be unreasonable for a creator or contributor to have different roles in a contribution so OK at least that makes sense. And then I go back to the introduction of the section and there is this:
the Cardinality field indicates the number of times the property MAY be attached to another property.
And now as someone who has to parse that, I must admit I’m not so sure what to make of that anymore. I know of at least one authoring app that will enforce only one meta for role, title-type, etc. (Zero or 1 cardinality) even if you put multiple in its metadata editor but are they right, or wrong?
Anyways, here’s a test file if that happens to be a bug.
