Johan,

You're describing a local repository, possibly a complete mirror. If you
examine the directory structure of the Fedora 14 updates repository,
you'll see it's quite straightforward:

        SRPMS/			<-- src.rpm packages
        	repodata/	<-- compressed metadata files
        i386/			<-- 32-bit i686 and noarch packages
        	drpms/		<-- x-y.drpm delta rpm packages
        	repodata/
        x86_64/			<-- 32-bit i686, noarch, 64-bit x86_64 rpms
        	drpms/
        	repodata/

In a full repo, you may find the same i686 and noarch packages in both
i386/ and x86_64/ directories. They should be hard linked.

You can use rsync to keep a local repo updated from a mirror site. With
modified .repo files in /etc/yum.repos.d/ that point to the local repo,
yum updates can be very fast.
