#74: Allow sharing of ancillary variables among multiple data variables ---------------------------------------+------------------------------------ Reporter: [email protected] | Owner: [email protected] Type: enhancement | Status: new Priority: medium | Milestone: Component: cf-conventions | Version: Resolution: | Keywords: "ancillary data" "standard name modifiers" ---------------------------------------+------------------------------------ Comment (by [email protected]): Dear All: This post defines "strawman" redlines to the CF standard to reflect this enhancement in the CF standard. (1) In paragraph 3.5 Flags ... Change example 3.3 to be: byte current_speed_qc(time, depth, lat, lon) ; current_speed_qc:long_name = "Current Speed Quality" ; current_speed_qc:standard_name = "status_flag" ; current_speed_qc:_FillValue = -128b ; current_speed_qc:valid_range = 0b, 2b ; current_speed_qc:flag_values = 0b, 1b, 2b ; current_speed_qc:flag_meanings = "quality_good sensor_nonfunctional outside_valid_range" ; The only change made to this example is the removal of the "sea_water_speed" from the flag variable's standard_name. Immediately after the example, add the following sentence: "Note that the data variable containing current speed has an ancillary_variables attribute with a value containing current_speed_qc." (2) In Appendix C. Standard Name Modifiers ... Add the following statement after the existing description for the number_of_observations modifier. "The use of this modifier is deprecated and the standard_name number_of_observations is preferred to describe this type of metadata variable." Add the following statement after the existing description for the status_flag modifier. "The use of this modifier is deprecated and the standard_name status_flag is preferred to describe this type of metadata variable." (3) Note that a post requesting standard_names status_flag and number_of_observations are posted to the CF metadata message board. very respectfully, randy -- Ticket URL: <https://cf-pcmdi.llnl.gov/trac/ticket/74#comment:52> CF Metadata <http://cf-pcmdi.llnl.gov/> CF Metadata This message came from the CF Trac system.
