Re: comments on http://www.w3.org/TR/2002/WD-rdf-scJust two quick comments on context -- stimulated by your previous comments on context. 1. Context is always important. Here's a trivial example. Dick McCullough is married. In the context of December 2002, this statement is false. In the context of any time between June 1960 and September 1996, it's true. Here's another example. Names denote things in the universe, and sets of triples denote truth-values. which is true in the context of your document http://www.w3.org/TR/2002/WD-rdf-mt-20021112/ but is false in the context of my document http://rhm.cdepot.net/doc/KEtutorial.txt. 2. Knowledge is advanced by integrating facts into a wider context. For example, in physics, force = mass x acceleration is a principle which integrates observed facts from many different contexts into a single context. By expanding that context to include variable mass and acceleration, we get a broader principle force = rate of change of momentum ============ Dick McCullough knowledge := man do identify od existent done knowledge haspart proposition list
