Hi Phil...

Just a suggestion ...

The aliases are a great way of extracting metadata from equivalent tags..

I use them to extract equivalent values from either the IPTC or XMP blocks..
ie. OriginalTransmissionReference or TransmissionReference

However, because aliases do not work for WRITE operations my code has to explicitly
set the individual tags if I wish to modify them...

Would be nice if I could just specify an alias and have ExifTool update all the relevant tags..

This would make my code cleaner as I can use aliases in the code and
configure the values which are written to from a single ImageExifTool configfile ....

What do you think ... ?
Is it an easy mod ?
Leave it with you, in case you ever modify this area....
