In an effort to fully describe data variables and unit specifications, NetCDF files have been infused where applicable with Darwin Core terminology and url tracebacks to the source material (http://www.tdwg.org/activities/darwincore/) along with explicitly prescribed units both for key spatiotemporal features (lat,long,depth) and in cases where variable names include unit indicators directly (e.g. "AttributeName_in_meters"). The preliminary *.json structure is shown here. Currently, the file is only a running list of terms, not parsed out by item number.

Other variables shown here are not Darwin Core terms. A similarly structured *.json vocabulary file of missing terms has been created to populate pertinent information patterned after the Darwin Core descriptions, for consistency. The missing definitions and information should probably be populated at least in part from SB records or inferred in some way.

Also, neither *.json vocabulary files contain a "unit" keyword at present, but it may be advantageous to include one, where applicable for dimensional variables, for the sake of clarity. Thus far, we're adhering to UDINT data standards.
