13.13 Efficient Dynamic Schema Changes
In netCDF-4, it is possible to efficiently add new metadata
- Without copying data, you can add
- new dimensions
- new variables
- new attributes
- new groups
- new user-defined types
- Lessens importance of getting schema design right the first time
- Makes archive maintenance easier
- Just as in netCDF-3, old programs just ignore new data objects,
continue to work OK
