When I see dublin core, I think of
that strange /dc/ in AD(sysadmin could not tell me why); or trying to understand RDF and EAV models.<p>A bit off-topic, <a href="https://www.freebase.com/" rel="nofollow">https://www.freebase.com/</a> is read only now, when it closes down what other open db for meta data is there? Something I don't have to crawl and have a decent query language?
Dublin Core: sure to be useful any day now.. Or not.<p>(Seriously, look at the Google Knowledge Vault paper, and pay attention to how much more accurate the data is that they get from non-metadata sources is).
