#95: Development of CF 1.5 Data Model -----------------------------+---------------------------------------------- Reporter: markh | Owner: [email protected] Type: task | Status: new Priority: medium | Milestone: Component: cf-conventions | Version: Resolution: | Keywords: -----------------------------+---------------------------------------------- Comment (by jonathan): Dear Mark Thanks for your comment. > In [comment:36 36] davidhassell first brought forward the idea that this collection should be unordered. I do not think this is a good approach, I think it causes issues of confusion and added complexity without adding utility, as far as I can see. In making this suggestion, I think David was intending to address a concern of yours by clarifying the situation. The domain axes which are used to dimension the data array must be in a certain order i.e. the order of the netCDF dimensions. But that is only a subset of the domain axes. There can also be domain axes of size one, not used to dimension the data array, whose logical existence is implied by CF-netCDF scalar coordinate variables. Since these are not used as dimensions, they do not have a particular order. Therefore it makes sense to David and me to say (as I did in my text) that the complete set of domain axes is an unordered collection, but the subset of them used to dimension the data array is an ordered list. Does that help? Cheers Jonathan -- Ticket URL: <https://cf-pcmdi.llnl.gov/trac/ticket/95#comment:57> CF Metadata <http://cf-pcmdi.llnl.gov/> CF Metadata This message came from the CF Trac system.
