put in HTML5 some predefinited prefixes for @itemprop:

dc = http://purl.org/dc/terms/
foaf = http://xmlns.com/foaf/0.1/
vcard = http://www.w3.org/2001/vcard-rdf/3.0#
owl = http://www.w3.org/2002/07/owl#
rdf = http://www.w3.org/1999/02/22-rdf-syntax-ns#
rdfs = http://www.w3.org/2000/01/rdf-schema#
sioc = http://rdfs.org/sioc/ns#
skos = http://www.w3.org/2004/02/skos/core#
xsd = http://www.w3.org/2001/XMLSchema#

also, instead of @item @itemprop @subject
is better @item @prop @subj
or @rdf-typeof @rdf-property @rdf-about (and @rdf-rel)
