 I've been slowly adding bits of RDFa into OpenPlaques. Here's how.
 Really, it isn't that difficult.
 It also isn't complete yet. There's loads more to do.

 This is just to show people that RDFa isn't very difficult! ;-)

    Initial support for RDFa
    
    added FOAF RDFa on person/show
    - Uses foaf:Agent, foaf:Person, vcard:VCard and rdfs/owl properties to link back people with dbpedia etc.
    
    update issue #244 - http://code.google.com/p/openplaques/issues/detail?id=244
    - if this gets changed, then the code introduced by this update will need to be changed too
    
    the doctype is now XHTML+RDFa 1.0 and has xmlns attributes for rdfs, vcard, foaf and owl.

    RDFa support for organisations
    
    I've used foaf:Organization to model organisations. I've used dc:title,
    rdfs:label and foaf:name for the name of the organisations, and used
    foaf:homepage and vcard:url for linking to the organisation's homepage.
    This seems pretty uncontroversial FOAF usage to me.
    
    Where I've gone a bit strange is I'm using foaf:made to relate the orgs
    to the plaques. This is slightly strange to me as it is really used to
    link to documents one has made like, say, blog posts or maybe academic
    articles etc.
    
    To say that a plaque is 'made' by a particular body like English
    Heritage or a particular local council is stretching it a bit. They are
    commissioned, perhaps. There are better English words for the
    relationship between the organisation and the plaque than the predicate
    'to make'. But 'foaf:made' isn't English, it's RDF. The FOAF
    specification doesn't specify exactly what situations one should use
    foaf:maker or foaf:made, except to say that it follows the same
    semantics (but not the same domain/range restrictions) as dc:creator. In
    the Dublin Core spec, it states that dc:creator is used to indicate an
    "entity primarily responsible for making the resource". Commissioning a
    plaque seems to count in my book. I'd rather reuse this than end up
    having to define some kind of spooky new relationship between plaque
    commissioner and plaque.

	RDFa support for organisations

	I've used foaf:Organization to model organisations. I've used dc:title,
	rdfs:label and foaf:name for the name of the organisations, and used
	foaf:homepage and vcard:url for linking to the organisation's homepage.
	This seems pretty uncontroversial FOAF usage to me.

	Where I've gone a bit strange is I'm using foaf:made to relate the orgs
	to the plaques. This is slightly strange to me as it is really used to
	link to documents one has made like, say, blog posts or maybe academic
	articles etc.

	To say that a plaque is 'made' by a particular body like English
	Heritage or a particular local council is stretching it a bit. They are
	commissioned, perhaps. There are better English words for the
	relationship between the organisation and the plaque than the predicate
	'to make'. But 'foaf:made' isn't English, it's RDF. The FOAF
	specification doesn't specify exactly what situations one should use
	foaf:maker or foaf:made, except to say that it follows the same
	semantics (but not the same domain/range restrictions) as dc:creator. In
	the Dublin Core spec, it states that dc:creator is used to indicate an
	"entity primarily responsible for making the resource". Commissioning a
	plaque seems to count in my book. I'd rather reuse this than end up
	having to define some kind of spooky new relationship between plaque
	commissioner and plaque.
