[GeoNetwork-users] Batch create metadata from images

Hi Everybody,

Is there any recommended way to create the geonetwork metadata filling its
fields with the metadata available in the images (such as geotiff).

I saw the app listgeo (http://www.remotesensing.org/geotiff/listgeo.html)
can dump to standard output the geotiff metadata.

Is there any tool or xlst template that could genereate a geonetwork
metadata in bach mode?

Thanks,
Alex Lopes Pereira
