I've prepared a *DRAFT* set of slides in PDF that deal with XML 
Linking, RDF an related fields. I'm looking for volunteers to review 
them and hopefully (not ;) to correct them. When I'm sure that there 
are no serious misunderstandings or errors and I haven't left out 
something, I'll release the slides under GPL.
Things I'm not sure of (Numbers reflect slide numbers)
4 : Is the notation urn:http://foo.com/ correct ?
6 : What really is the difference between document and group ?
  : Do you consider the visualization an oversimplification ?
7 : Any idea how to generally visiualize the concept of a 
    link without discriminating inline/off-line and simple/extended ?
  : May a locator really be a link of type locator ?
9 : Have I missed a feature ?
10: Formalisms tend to be erroneous, please check.
11:    "         "   "  "      "       "      "  .
12: Maybe someone has a good summary of the state of discussion ?
