Kingsley mentioned the magic word, I think, "complex". Reification, thanks for the spelling, is a funny word and an uninformative label. I would much rather the "Data Repository Déjà Vu Principle". If you throw something straight up it lands on your head - that's where the déjà vu concept comes in. Linked Data would be much better thought of without this "IT owned" magic component. Specifically, the example of rows and columns of a spreadsheet should be used so as to demonstrate that the manipulation of row and column indexes are (an RDF List is) not exactly as simple as it seems, but not "complex" in the sense of complex numbers. The simple "99% solution - part per hundred" (Range*(100/99)) is divergent from the centre of mass. Part per Million diverges slower. This can easily be seen by computing the (Mean*Count)=(Sum) or (Variance). A unit matrix only has one configuration (Transpose), and there is no "creeping up" on identity - that produces imaginary outliers, not Chaos but rather "premature reification" (I like that one Frans) or maybe better "immature reification". --Gannon ------------------------------------------------------------------------------------------------------------ Regards, Frans Regards, Kingsley Idehen Founder & CEO OpenLink Software Company Web: http://www.openlinksw.com Personal Weblog 1: http://kidehen.blogspot.com Personal Weblog 2: http://www.openlinksw.com/blog/~kidehen Twitter Profile: https://twitter.com/kidehen Google+ Profile: https://plus.google.com/+KingsleyIdehen/about LinkedIn Profile: http://www.linkedin.com/in/kidehen Personal WebID: http://kingsley.idehen.net/dataspace/person/kidehen#this Frans Knibbe Geodan President Kennedylaan 1 1079 MB Amsterdam (NL) T +31 (0)20 - 5711 347 E [email protected] www.geodan.nl | disclaimer
