Karl,
   First off, yes I'm still writing that essay :) I might put an in- 
progress version up if you want to see some text.

   Secondly, responses inline!

Those properties look exactly like my photo schema, which is good  
news for me (even down to "square"!).

<http://www.holygoat.co.uk/owl/2005/05/photo/>

The schema is actually discussed in detail in my essay, so if you  
want to know more I'll send you a copy.

It's questionable at which level the "Photograph" -- "Image file"  
distinction is made.

I would tend to think that there's a blurring between the Work and  
Expression for <http://www.flickr.com/photos/karl/36680383/>, then  
each resource which always gets sent as the same sequence of bytes is  
a manifestation, of which there are multiple items. (Or something  
like that, anyway.)

My existing schema is only two-level for this reason, but it needs a  
lot of thought.

Bruce D'Arcus has some interesting input about photography, and how  
different developments and prints are likely to produce new  
expressions, manifestations, and items. It's complex, which has  
slowed me down :)

FRBR parts. The set is a work, the page showing the set is lower down  
the hierarchy, as is the document itself. The components tie in at  
each level -- the conceptual set has the conceptual images as its  
parts, while the page set has the manifestations as its parts.

This ought to be cast down.

I came up with a thumbnail property. A thumbnail is a derived 'thing'  
forked from the main FRBR tree.

Isn't the CC stuff described the RDF anyway? Seems like one could  
just hang the appropriate triple off of whichever level at which you  
wish to apply the license.
