Tagging multiple prefixes within an S3 bucket for lifecycle rule application.

Question

Hi,
I wanted to find out what the easiest way for me to be able to apply lifecycle rules a large subset of prefixes within my S3 bucket but still being able to use other lifecycle rules (with longer transition/expiration settings) to a smaller subset of prefixes.

One way I have thought this may be possible is to tag all of the prefixes that will have the larger blanket lifecycle rule applied to them however I wanted to find out how I may go about tagging these prefixes. It's worth noting that all of these prefixes would have 1000s of objects within them.

A follow up question - Even if it possible to tag by prefix, will new objects created with that prefix automatically have the tag applied to them or will this tagging process need to be carried out frequently.

Thanks!

Unfortunately, I don't think tags can be set for S3 prefixes.  
Set tags on the object instead.

Tags can be set on the object either at upload time or after upload.  
If done with AWS CLI, it will look like this.  
```
aws s3api put-object --bucket example-bucket --body test.txt --key test/key --tagging Key1=Value1
```
