Lightroom API reference for metadata read/write - specifically facial data

[darrenb34662519]

I'm looking for documentation for Lightroom classic related to reading and writing metadata for the catalog (file metadata and data stored in the catalog).  I'm specifically interested in the data related to facial data (regions defined for face in an image, name associated with region, etc).  I've been hunting and playing with the SDKs for a couple days and I can't find what I'm looking for (beyond basic IPTC/EXIF metadata).

The region metadata isn't available via the SDK, unfortunately. The only way for a plugin to get access to that metadata is to read it from the file's metadata, e.g. using ExifTool.
