Thanks.  I'm just getting around to looking at this.  As usual, the spec is poorly written, incomplete, and full of errors.  Plus, it isn't very backward compatible.  I'll see what I can do with this mess.

I'm trying to get my head around the new Annotations box.  I guess it's in APP11 and JUMBF, allowing JSON-LD or XML values.  And also in exifEX?  Argh.

Phil, I don't believe you've cracked this pistachio?  Or have I overlooked it?  - J

ExifTool 12.63 added some support for some of the new Exif 3.0 features.  ExifTool already supported APP11 JUMBF (for reading only).
