Hi Kingsley,In the case that Michael describes, could one reasonably expect that if the BBC were to embed the following triples as RDFa in the HTML served on the URL http://www.bbc.co.uk/programmes/b006mw1h, then a webcrawler would understand to go directly to the webpages about the seasons and episodes?
Absolutely!! They could even use the following within <head/> :1. <link @rel="{relation-or-predicate-identifier}" href="{relation-object}" ../> -- indicating that the doc in question is the subject of a relation denoted by {relation-or-predicate-identifier}
2. <link @rev="{relation-or-predicate-identifier}" href="{relation-subject}" ../> -- indicating that the doc in question is the object of a relation denoted by {relation-or-predicate-identifier} .
Even up the ante, for smart HTTP user agents by replicating the relations above using "Link:" response headers.
And to make your example live, I am tweaking your Turtle Snippet (aka. Nanotation) which will produce some interesting results. Note, my only change is a Nanotation parser hint i.e., ## Turtle Start ## and ## Turtle End ## :-)
