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

[Jared Rubin]

I am inheriting from the RawDataset because it is scan line orientated and 
would like to stuff metadata like sensor zenith, sun azimuth, etc.. that are 
well defined metadata items in NITF and TIFF so that I can convert an 
internal image format to NITF or TIFF. Is there a specific domain that I need 
to use for NITF or TIFF for stuffing the metadata. If so can someone provide 
an example?
   In addition, if i was to stuff the metadata to NITF, would it carry over to 
TIFF?

Basically if run gdal_translate from my internal format to NITF and then run 
gdal_translate from NITF to TIFF would the metadata carry over to TIFF?

Thanks
Jared
