Simple JSON to Tag mapping

Hi,

I already looked for a JSON mapping, but I can't really find one.

I have already a JSON service, which is queried by GET http://myservice.local/service/{filename}

So I put the filename in my GET query and i get a JSON

{
  "ALBUM": "foo",
  "ARTIST": "bar",
  ...
}

How do I handle that in MP3Tag?

Thanks a lot
