Mwg regions face tagging

[neebah]

I'm writing a little application for face tagging as I don't trust Picasa or Microsoft.  This will call exiftool directly.  What commands should I use to place the face info in the Mwg regions xmp info

See the Serialization section of the Structured information page for an example of this.

Okay I think I have the jist of what to do from the documentation.  Since I'm storing to mwg should I used -XMP-mwg-rs  instead of -RegionInfo

RegionInfo is a structured MWG tag.  See the  MWG Regions tags documenation for details.

Okay I've got how the INFILE works with adding an entire face to the MWG region.  Is it possible to target a face by description or name and change just the name and leave the other parts the same or vice versa.

I haven't tried anything like that but I faintly remember something previously posted...

From the Structured information page:
"When deleting and adding back items in lists in the same command, new items are inserted at the point in the list where the first item was removed, or at the end of the list if no items were deleted. This applies to lists of structures as well as simple lists of string values, and provides a mechanism to replace a specific structure or field."

Also, just doing a substitution from this post.
