@Revertron Good question, and I don't have a definite answer. Perhaps databases can be identified by a public key of an authority (or something akin to a multisig address)? A fully qualified name may look like this:
myname.z6MkhaXgBZDvotDkL5257faiztiGiC2QtKLGpbnnEGta2doK.namesystemThat makes it poor DNS alternative (names are not human readable), but it's good enough for decentralized identity
