Subject: give the methods more metadata about the files to acquire

We have quite a bit of metadata available for the files we acquire, but
the methods weren't told about it and got just the URI. That is indeed
fine for most, but to avoid methods trying to parse the metadata out of
the provided URIs (and fail horribly in edgecases) we can just as well
be nice and tell them stuff directly.
