Capture VNAMEs when converting NA to NC

One thing that came up for me was that it might be useful (for me at least ^^) to dump VNAMEs when converting na to nc (i.e. to a global attribute maybe). The VNAMEs I have to deal with are not exactly standard and I want to provide sufficient info on those variables in the netCDF file as well (so the user doesn't have to open the na file additionally).

Do you want to propose a global attribute such as vnames_from_source_data ?

@FObersteiner said:

yes, that sounds reasonable.
Another option might be to set the original VNAME from the na file as an attribute of the xr.DataArray (make a "vname_from_source_data" tag).

@FObersteiner: I like your idea that the xr.DataArray (i.e. the NetCDF variable) would hold the original VNAME from the NA file.

vname_from_source_data sounds good to me.

Please confirm this is still your preferred option.

Hi Ag, I've been busy with (mostly not data related) other stuff in the last few weeks, so I totally missed your question - sorry.

Yes, the above would still be me. Having a global attr would also be fine I guess if you see an advantage - I'll leave that to you ;-)
