#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 ngalbraith): ''For example, if a file has a comment field, and the variable has a comment field, these might be aggregated in the data model to produce a resulting variable with two comment fields (it doesn't seem unreasonable to me that there would be valid use cases for this).'' I also thought of the history attribute; if globals are really meant to be replaced by variable attributes during subsetting or aggregation, then I have a big problem, as does almost anyone who stores observational data in CF. The early processing steps of each variable in an observational file may be different, and so are recorded as variable attributes, while processes performed later - after all the variables are put into a single file - are recorded as globals. If the global history is discarded, we've lost a significant chunk of provenance. -- Ticket URL: <https://cf-pcmdi.llnl.gov/trac/ticket/95#comment:94> CF Metadata <http://cf-pcmdi.llnl.gov/> CF Metadata This message came from the CF Trac system.
