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! -R On 6 Sep 2005, at 11:17, Karl Dubost wrote: > > There is a photography > http://www.flickr.com/photos/karl/36680383/ > The title is > "The gardener slipped through the cracks" > The photo belongs to this set > http://www.flickr.com/photos/karl/sets/659154/ > The owner is > "Karl Dubost" > The foaf file is > http://www.la-grange.net/karl-foaf.xrdf > Original uploaded version of the image is at > http://static.flickr.com/22/36680383_072987e88e_o_d.jpg > The Square Thumbnail is at > http://static.flickr.com/22/36680383_072987e88e_s_d.jpg > The license is > http://creativecommons.org/licenses/by-nc-nd/2.0/ > The tags for the image are > http://www.flickr.com/photos/karl/tags/montreal/ > http://www.flickr.com/photos/karl/tags/quebec/ > http://www.flickr.com/photos/karl/tags/canada/ > http://www.flickr.com/photos/karl/tags/chair/ > http://www.flickr.com/photos/karl/tags/sidewalk/ 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. > <http://www.flickr.com/photos/karl/36680383/> > a frbr:Work; > frbr:Person <#karl_dubost>; > dc:title "The gardener slipped through the cracks"@en ; > dc:date "2005-07-31"; > frbr:subject <http://www.flickr.com/photos/karl/tags/montreal/> ; > frbr:subject <http://www.flickr.com/photos/karl/tags/quebec/> ; > frbr:subject <http://www.flickr.com/photos/karl/tags/canada/> ; > frbr:subject <http://www.flickr.com/photos/karl/tags/chair/> ; > frbr:subject <http://www.flickr.com/photos/karl/tags/sidewalk/> ; > frbr:realization <http://static.flickr.com/ > 22/36680383_072987e88e_o_d.jpg> . 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 :) > QUESTIONS: > I haven't figured out to express the following things. Any help? > > The photo belongs to this set > http://www.flickr.com/photos/karl/sets/659154/ 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. > The Square Thumbnail is at > http://static.flickr.com/22/36680383_072987e88e_s_d.jpg I came up with a thumbnail property. A thumbnail is a derived 'thing' forked from the main FRBR tree. > The license is > http://creativecommons.org/licenses/by-nc-nd/2.0/ 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.
