Awesome! @prefix dc: <http://purl.org/dc/terms/>. <> dc:author []. <> <> <> . [] <> [] .

And since <> is general, we can take it as referring not just to identity but to space-time location, yielding <> = sum-here-now. Then if we discard the notion that RDF triples must be translatable directly or naturally to Subject-Verb-Object constructions in some natural language, we can write > > <> <> <> . > > At least I think we can. I'm not sure how best to gloss it; something like "every doc is related to itself by itself (in space-time)"? Which is kinda sorta like "I am", if you squint hard enough. > > It won't get published in Philosphical Quarterly any time soon, but it makes for a pretty good RDF riddle. > > -Gregg > > > > >> On 2017-05 -18, at 22:54, Gregg Reynolds <dev@mobileink.com <mailto:dev@mobileink.com>> wrote: >> >> >> >> On May 17, 2017 4:46 PM, "Sarven Capadisli" <info@csarven.ca <mailto:info@csarven.ca>> wrote: >> Philosophers and Semantic Web junkies gather around. >> >> Use the the RDF language to represent the following statement: >> >> "I am." >> >> obviously not possible, since "I" is an indexical.
