As the question states, is there any point adding Dublin Core meta-tags to your HTML head? Or has sitemap.org removed the use for most of this (though it only replaces some of the tags)
I ask this as most sites I visit don't seem to use DC metatags in their source.
I'm interested in whether I need them for a site that will be used mostly for developers, however the discussion can be broader than this category.
To quote Google (from 2002):
"Currently we don't trust metadata because we are afraid of it being manipulated"
Originally developed to describe web resources, Dublin Core has been used to describe a variety of physical and digital resources. Dublin Core is comprised of 15 “core” metadata elements; whereas the "qualified" Dublin Core set includes additional metadata elements to provide for greater specificity and granularity.
The original Dublin Core™ of thirteen (later fifteen) elements was first published in the report of a workshop in 1995. In 1998, this was formalized in the Internet Engineering Task Force standard RFC 5791, and discussions began about making it a standard of the (US) National Information Standards Organization (NISO).
I would rather say that the time of rich metadata hasn’t come yet. In fact technologies like RFD are just on the way up. Tim Berners-Lee – you know, the guy who invented the web – quite recently spoke at TED about The next Web of open, linked data. So Dublin Core and other metadata formats are anything but out.
