#107: CF Data Model 1.7 -----------------------------+---------------------------------------------- Reporter: markh | Owner: [email protected] Type: task | Status: new Priority: medium | Milestone: Component: cf-conventions | Version: Resolution: | Keywords: -----------------------------+---------------------------------------------- Comment (by davidhassell): Replying to [comment:15 markh]: After the discussions in #95, I think it was agreed that these attributes do apply to every data variable in the file, although ''how'' they apply had varying interpretations and was not resolved. So in that light, I think that they ok to be mentioned. All the best, David > I would like to raise a concern regarding the proposed text for [wiki:Ticket107Text9Nov13Properties properties]. > > There is explicit mention of: > * Conventions > * history > * title > * featureType > > as property names valid for Field instances. > > The CF-NetCDF conventions describe these as file attributes, not valid for individual data variables, in [http://cf-pcmdi.llnl.gov/documents/cf- conventions/1.6/apa.html Appendix A]. > > I can see how featureType and Conventions could be treated as spanning across data variables, and the 'file only' constraint for NetCDF files being a logical extension of how CF instances are encode in NetCDF. As such I am not concerned by these two. > > However, the use of history and title is inherited from the [http://www.unidata.ucar.edu/software/netcdf/docs/netcdf.html#Attribute- Conventions NUG] and their use is heavily linked to files, collections of Fields. > > As the data model does not have a sense of 'a collection of fields' I suggest that these are removed from the data model and put into the list of reserved property names, not to be used except in NetCDF files. -- Ticket URL: <https://cf-pcmdi.llnl.gov/trac/ticket/107#comment:16> CF Metadata <http://cf-pcmdi.llnl.gov/> CF Metadata This message came from the CF Trac system.
