I would go beyond that: I do not think ARIA is the right tool for this, conceptually.

As far as I am concerned, I make some difference between ARIA and RDFa/µdata. ARIA provides "semantics", ie, structural information, about the HTML page itself. It adds a semantic layer on top of the tag soup to describe what a tag is used for. RDFa/µdata, on the other hand, uses the HTML tags to provide semantics about something else, which is not, per se, part of the HTML page. Using URI-s for this purpose is one of the strengths of RDF(a). In this case, RDFa/µdata provides semantics about an article through its reference (DOI, HTTP URL, whatever). ARIA cannot, and shouldn't, do that.

It is a subtle difference, but an important one imho. In this respect, expressing structural semantics with ARIA is the right thing to do; but expressing bibliographical information of an article which is not part of the current document isn't, at least in my opinion.

B.t.w., I would be interested to see a comparison between the JATS and the BIBO terms. BIBO is an RDF vocabulary, and hence can be readily used (and is used in some places) to describe bibliographical items using, eg, RDFa. I have never looked at JATS but if we really feel it is necessary to represent that in terms of an RDFa vocabulary, the good thing would be to map it on top of BIBO and not to re-create yet another vocabulary (there are also at least 3 different mappings of BiBTeX to RDF, for example, all incomplete from a publisher's point of view; we should try to avoid this type of proliferation).
