Does PM support image region metadata (face tagging)?

[justink]

I understand that XMP allows for tagging specific regions of an image (like faces) with specific descriptions (like names) and then embedding that data with the image. Does Photo Mechanic allow this? If not, is it planned feature for any time in the future?

I don't think it does.  What XMP fields are used for this data?

I don't really know exactly how it's supposed to work. It may not be a visible field that you directly type in. I think it requires a relatively sophisticated user interface where the user would highlight a region within the image and then attach a name to that region and the software then codes it into XMP in a way that looks like this:
...

Justin,

Thanks for the info.  No, PM does not support those fields.  We have no plans to support them in the near future.
