it seems to me that knowing that a token refers to a thing or resource is just about worthless and doesn't motivate the extra bits needed to say it ...
Sorry, that might be true in the Semantic Web (yes, I know this is the SemWeb list), but in the Linked Data world, all you need is the URI.
You can find out the type (if you really want it) by resolving the URI.
And in fact you get a much more reliable ID for the type - the one that the system that coined the URI meant, rather than a possibly mistyped or otherwise mangled type that some bozo author put there.

I don't see any need to make anything more complex than the URI.
The proposal was to try and create the simplest possible way of disambiguating natural language terms in normal text by enabling authors to draw on existing vocabularies (or possibly a new one).
There really is no need to complicate it, and the downside is that if you do it won't get used.

Of course, quite a common thing as research tries to move into major use, but something to try and avoid.

after all that can always be assumed for everything.   I would rather want to know to which class of things it belongs.

I suggest something more like this:
<p>It is well known, that <span about="http://sws.geonames.org/4951788/" typeof="geo:City" >Springfield</span> has mild summers and short, but hard winters.</p>

Of course you guys would need to have the courage to actually agree to start using standard names.

In addition to my first proposal: Of course, you could also consider http://schema.org/Thing or rdfs:Resource instead of owl:Thing:

All three express roughly the same and should validate, assumed you use an RDFa 1.1 DOCTYPE.

Also, the semantics is as intended: You express that there is an entity, whose type is not further specified, and that one know identifier for the identity is the URI given. I think this is slightly better than just assigning the identifier via @resource.
