Re: LD 5th Element ?

hello Kingsley,

3. "When someone looks up a URI, provide useful information, using the standards (RDF*, SPARQL)"

This sentence is strongly targeting the 'look up' case. If you replace "look up" in the sentance above with 'interact with', it misses a lot of the essence of that interaction.

So, I prefer "interactions they facilitate" !!
