Dennis,
You can add user-defined metadata via dynamic properties of PutS3Object
itself (no UpdateAttribute needed). Plus (+) icon at the top-right corner
on the processor properties tab.
The name of the dynamic property will be the key (or name) of the
user-defined metadata.
The value of the dynamic property will be the value of the user-defined
metadata. You can use expression language for the value (eg. referencing FF
attributes or now() for the timestamp).
Hope it helps.
Best,
Peter Turcsanyi
