Module attributes 

Filter and convert HDF5 attributes to NetCDF-4 attributes.

NetCDF-4 uses several internal HDF5 attributes that should not be exposed to users:

• _NCProperties: file provenance metadata
• _Netcdf4Dimid: dimension ID assignment
• _Netcdf4Coordinates: coordinate variable tracking
• DIMENSION_LIST: dimension-to-variable references
• REFERENCE_LIST: variable-to-dimension back-references
• CLASS: dimension scale marker
• NAME: dimension scale name

Functions

extract_group_attributes

Extract user-visible attributes from an HDF5 group, filtering out internal NetCDF-4 attributes.

extract_variable_attributes

Extract user-visible attributes from an HDF5 dataset, filtering out internal attributes.

is_internal_attribute

Returns true if the given attribute name is an internal NetCDF-4/HDF5 attribute that should not be exposed to users.
