Why not use Dublin Core? [1][2][3] Here is a template.[4] (IANA provides some kind of directory convention by which one can form URIs from MIME types.) <meta name="DC.Identifier" content="--Namespace URL here--" /> <meta name="DC.Title" content="--Title here--" /> <meta name="DC.Creator" content="--Creator here--" /> <meta name="DC.Subject" content="--Subject here--" /> <meta name="DC.Date" content="2001-mm-dd" /> <meta name="DC.Type" content="dataset" /> <meta name="DC.Type" content="text" /> <meta name="DC.Description" content= "A Resource Description Directory, using the RDDL format of rddl.org" /> <meta name="DC.Format" content="text/html" /> <meta name="DC.Language" content="en" /> <link rel= "schema.DC" href= "http://purl.org/DC/elements/1.1/" /> Or, better, because then we don't need some system that undertands the use of "link", embed an RDF section: <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:dc="http://purl.org/dc/elements/1.1/"> <!-- change these --> <rdf:Description about="--URL Here--"> <dc:title>--Title here--</dc:title> <dc:creator>--Creator here-- </dc:creator> <dc:subject>--Subject here--</dc:subject> <dc:date>2001-mm-dd</dc:date> <dc:language>en</dc:language> <!-- don't change these --> <dc:type>dataset</dc:type> <dc:type>text</dc:type> <dc:description>A Resource Description Directory, using the RDDL format of rddl.org</dc:description> <dc:format>application/xhtml+xml</dc:format> </rdf:Description> </rdf:RDF> But rddl:class would be terser.
