A number of raster image processing problems MAY require the support of more metadata that is contained in the image itself.
Applications MAY use the gpkg_metadata and gpkg_metadata_reference tables defined in clause [_metadata] to store raster image metadata defined according to standard authoritative or application or vendor specific metadata models.
An example of the data items in such a model is shown in the following table.
