Pharaonic navigation has an advantage here in that (ignoring protests of some historians, I'm sure) there are commonly defined, named periods with determinate endpoints. It would be possible to suggest some vocabulary to incorporate them. But that wouldn't provide many linkages to currently-known partners, and it wouldn't accurately describe most of the collection. So, what other approach would be more appropriate and inclusive?
