Question:

Is there a way to add and modify metadata in aws_s3 in vb6?

Answer

I created an example. (See below for the link that is to the VB6 example.)

I reviewed the S3 REST API reference, and did not find anything to update metadata. I also found this: http://stackoverflow.com/questions/32646646/how-do-i-update-metadata-for-an-existing-amazon-s3-file

Each Amazon S3 object has data, a key, and metadata. Object key (or key name) uniquely identifies the object in a bucket. Object metadata is a set of name-value pairs. You can set object metadata at the time you upload it. After you upload the object, you cannot modify object metadata. The only way to modify object metadata is to make a copy of the object and set the metadata.
