[Gdal-dev] loading metadata into NITF from separate image format

[Jared Rubin]

Sophia,
  I am have my own internal image format and would like to stuff metadata into 
a nitf file without relying upon the command line. So for example I want to 
place the  ANGLE_TO_NORTH into the USE00A tag for NITF.
I am inheriting from RawDataSet

I see the that the nitf library  uses
GDALPamDataset->SetMetadata
and 
GDALPamDataset->SetMetadataItem

is this how the metadata gets passed between image formats?

thanks
Jared
