As Anne and Julian have pointed out, that's not a use of data-*  
attributes permitted by the spec.

That would be an abuse of data-* attributes as well. The data-*  
attributes are for scripts included by the page itself. The data-*  
attributes aren't for communication with other parties.

Having something-other-than-data-curie="dc:http://purl.org/dc/elements/1.1/ 
" or somesuch would work around the layering problem of that qnames-in- 
content have (and CURIEs have, too, when using the namespace mapping  
context). It leaves the problem that making URLs shorter (in the  
amortized sense) by introducing a supposedly insignificant prefix  
confuses people and makes stuff brittle under copying and pasting.

Why not property="http://the.entire.full/uri/here/if/you/really/want/uris/as#identifiers 
"?
