	-- primer/tutorial/examples, incl intro to URIs, XML, namespaces
		-- perhaps an extended primer, including
		suggesions on how to do n-ary stuff,
		things versus their names, etc.

		materials to draw from include [1,2,3]

	-- Abstract syntax (i.e. what's common between
		RDF/xml and n-triples)

	-- existential/conjunctive semantics
		-- <rdf:Description><dc:title>xyz</dc:title></>
		means "there exists something with title 'xyz'"

		cf [2]
		and n-triples2kif.pl

	-- RDF/xml syntax: bare bones plus
		abbreviations: typednodes, attribute/element stuff, etc.
		specified using XSLT and/or XML Schema

	-- literals and datatypes
		xml:lang, parseType="Literal"
		(eventually: XML Schema datatypes)

	-- schema:
		-- housekeeping: label, comment, isDefinedBy, ...
		-- inference: type, subClassOf, subPropertyOf,
			domain, range, ...

	-- collections (for what they're worth ;-)

	-- reification (there be dragons ;-)
		ID on propElt, aboutEach, bagID

	-- rules.
		er. ahem. getting ahead of myself a bit ;-)
