Hi! Thanks for the question. We have datasets, which are analogous to Git's branches. This is the only mutable state in Noms, and it's just a pointer into the graph. We also have paths (https://github.com/attic-labs/noms/blob/master/doc/spelling.md https://github.com/attic-labs/noms/blob/master/doc/spelling....), which can be used to reference a stable path deep into the tree. We have ideas about how to create short, stable IDs that are unique across the database, but haven't had a strong use case yet.
