Subject: RE: [xri] RE: [xdi] Global Cross-Reference Proposal
Les, you're right that in both @cordance=drummond and @cordance*(=drummond), you can infer a semantic relationship between the subsegments (@cordance and =drummond) and their global XRIs. However, in the latter case, I think the only interpretation you can infer is that the entity being referred to by *(=drummond) is being referred to IN A DIFFERENT CONTEXT than =drummond. The rationale is the same as the example I gave in natural language on the wiki page, which is when quotes are used in English to explicitly communicate that a particular word/phrase is being used in "quotes", specifically what are called "scare quotes" (thanks to John Bradley for educating me about that phrase). There's a good Wikipedia article on scare quotes: http://en.wikipedia.org/wiki/Scare_quote The example I used on the wiki page was: Boeing "international" employment contract signature date In that phrase, the only thing an English reader can interpret about the word "international" is that it is being used in a different context than the normal use of the word. I think it's safe to say that in order to understand what context applies (and therefore what the word really means in that context), you have to look either at the immediate context of the full sentence, or the full paragraph, or the full context in which it appears. Which is exactly the meaning of "local context symbols" in XRI. Therefore the following line up nicely: Boeing "international" employment contract signature date @boeing*(+international)+employment$contract$sig$d ...and... Boeing international employment contract signature date @boeing+international+employment$contract$sig$d I don't think there's any more semantics that can be interpreted from the difference. However I think you can see why the issue is so important to XRI 3.0 -- in XRI 2.0 the _only_ cross-reference that can be expressed in the "scare quote" version, whereas in normal natural language (as in typical XDI RDF), it's the global cross-reference version that's needed.
