Thanks-- > In fact, I briefly considered using 'aboutEach' to allow a more direct harvesting of Links that used roles to identify several resources. I dropped that idea as being needlessly complex, and went with the approach where each traversal arc gave rise to a single RDF statement. RonReceived on Friday, 2 June 2000 10:30:34 UTC
