can one download historic onionoo documents (details.json) archived somewhere or would one have to setup onionoo + feed old data into it to achieve that? There are no archives of Onionoo's documents.
But of course there are CollecTor's archives which you'd feed into Onionoo. Though it's very likely easier to parse those directly (possibly using Stem) rather than setting up an Onionoo instance for the exact time you're interested in.
Speaking of, what historic data are you looking for? Maybe it's something that we should add to Onionoo itself?
I've a few use case for onionoo data, one of them uses onionoo to find groups of relays run by one entity. First_seen combined with last_restarted has proven to be a rather good datapoint for that. Using an array of all restarts (instead of just one) would likely reduce false-positives even more.
So, the problem here is that an array of restarts doesn't scale, so it would have to be limited to the last 10 restarts or so. But even that is not trivial to implement in Onionoo and, as you note below, it's quite specific and not very useful for the average Onionoo client. What you could try is evaluate uptime documents and see if two relays had similar uptime patterns over time: https://onionoo.torproject.org/protocol.html#uptime
That is one field but I'll consider (historic) changes to other fields (contactinfo, orport, dirport, ...) as well.
Although I could imagine atlas displaying data like "these were previously provided contact details: ..." most of my use cases are to uncommon to add to onionoo.
I think I agree with you here. Also, you're much more flexible by using descriptors directly and adapting what you're extracting from them rather than having to wait for me to add a new field to an Onionoo document. By the way, are you aware of Philipp Winter's work on a better Sybil attack detector? He's cc'ed in case you want to brainstorm about good criteria for comparing relays.
