Hey Brand:
(07)
I understand the video's not ready yet, but should show up here [1] when
(08)
ready.
(09)
BTW - for those interested in the LOD existential question, I wanted to
suggest the strictest interpretation should follow from the four steps
or rules in the following page of design issues. [2]
(010)
Note that step three prescribes the use of standards, then identifies
two standards (RDF*, SPARQL). Not sure how to interpret the rather loose
(011)
syntax of the page.
