Brian: Data is encoded values in a proposition that is supposed to be true.

I don't think denotation is part of data. For example, in one year a near record snowfall that fell in the northeast is attributed to global warming even though the same amount of snow fell 100 years earlier when the globe wasn't as warm.

Once you attribute meaning to data, you're on a slippery slope. Received on Wed Feb 13 2008 - 16:17:41 CET
