My guess is that you're looking for the on-disk format document: http://www.opensolaris.org/os/community/zfs/docs/ondiskformat0822.pdf
If you're more interested in the user-visible metadata (e.g. the settings for pools and filesystems), then you'd probably have to dig through the various manual pages.
