I just came up with a name for the versioning scheme I've been using recently: Zettelkasten versioning 1, 2, 3, ... 14, 14a, 14b, ... 14z, 14aa, ... 14ak1, 14ak2, ... https://zettelkasten.de/introduction/#the-fixed-address-of-each-note My versions are to communicate identity. That's it. Not ordering, not value, not recency, not stability, not compatibility, not quantity of change, not support duration, just identity. Am I using the same version as you? (The easiest way to come up with versions also ends up communicating heredity. But that's an unimportant side effect.)

I don't understand. If all you care about is identity, why not just use incrementing numeric IDs? The zettelkasten thing is designed specifically to enable hierarchy, isn't it?

Yeah. Upon further reflection, I realized I didn't want my users to have to care about what versions mean. But it is helpful to the programmers to be able to see some indication of the heredity. So I was not right in my final paragraph. On the other hand, we only see heredity from one side in this scheme.. 🤔

Yeah, if identity is all we want, I know this git who has something on offer. 😏
