Re: [CF-metadata] [sdn2-tech] RE: proposed standard names for Enterococcus and Clostridium perfringens
Hi Roy, Don't get me wrong. I am supportive. My email was from one traveler to another, letting Alessandra know what was on the road ahead. I have argued in the past in favor of having chemicals be a separate variable/dimension. And I still think it would be a good idea. Hence, I would support it for taxa too. My warning was that there are complications, and to expect resistance. I also wanted to say that 'losing' the argument isn't quite as terrible as it would first seem. I think we will need to shift to separating out chemicals and taxa eventually. Good luck, Philip Sent by Philip Cameron-Smith from his blackberry. - Original Message - From: Lowry, Roy K.

Hi John, Which is exactly how it is in CF for 2-m air temperature or irradiance of a specified wavelength. Trac ticket 96 is aimed at providing your magical connection and could be used for taxon names. Ever get the feeling that some of the CF discussions (e.g. ISO8601) are a case of identifying the lesser of two evils by people with different opinions on what constitutes evil? Cheers, Roy.
