The directory protocol is described at

Indeed you did. The old protocol is at
http://tor.eff.org/svn/trunk/doc/dir-spec-v0.txt
The storage format is undocumented, and intentionally so: we may
change it without warning, so please don't rely on it. But basically,
the old format was just to store a raw directory to disk. The new
format is to store a network status document for each authority in a
file named cached-status/<authority-fingerprint> (with the authority's
fingerprint given in hex); and to store the router descriptors
concatenated in cached-routers and cached-routers.new. The latter is
append-only, and used as a journal; periodically, we prune out unused
router descriptors and regenerate cached-routers.
The source (in routerlist.c) should have full information.
