Ok, that might not be so bad.  I think the reason I settled on
foaf:topic was partially also because I wanted to be able to disinguish
my photo events with these conference-type events for my browsing
interface.  I want to show:

  Trip to Tokyo 2004
    Attending SVG Open 2004

rather than:

  Trip to Tokyo 2004
    SVG Open 2004
      My attending SVG Open 2004

but I guess I could do this differentiation a different way (for example
by omitting events that are not explicitly the dc:coverage of any
photos).

So if I have a photo described as:

  <http://example.org/photos/2004/09/p1.jpg> a foaf:Image ;
  	dc:coverage <http://example.org/events/2004/09/SVGOpen> .
  <http://example.org/events/2004/09/SVGOpen> a cyc:Event ;
  	cyc:subEvents [ foaf:homepage <http://www.svgopen.org/2004/> ] .

How can I maximise the possibility that people searching for photos from
SVG Open 2004 will find my photo, which has a dc:coverage of my
attendance of SVG Open 2004?  Can RDFS or OWL rules be written so that
queries for photos that have

  dc:coverage [ foaf:homepage <http://www.svgopen.org/2004/> ]

will work here?

Thanks,

Cameron
