RDFa is emitted by HathiTrust's pageturner application.
I believe that COinS support is available for all text collections
delivered using DLXS on quod.lib.umich.edu. Furthermore, those
MPublishing text collections on quod.lib.umich.edu that use a newer
design templates include minimal RDFa and, for what it's worth, also
follow the Google Scholar Inclusion Guidelines. (We are migrating
collections to the new templates, so the number will increase over time.)
It's a shame that unAPI never caught on. See previous discussions on
this list about the virtues of unAPI over COinS.
