Resend: Memento Support

Nelson, Michael L.
Sorry for the delay in answering; things are still kind of crazy.
Thanks for working on Memento support.
Looking at:

rel="timegate" should be: rel="timemap"
also, the TimeMap response should send back 404s (and not soft 404s) if they don't have the page archived:

I just archived that page, but I guess the index had not been updated yet:
https://ghostarchive.org/archive/mXi9j?kreymer=true
Arguably more important than TimeMap or TimeGate support is getting the mementos to self-identify:

should have a Memento-Datetime header, like:
Memento-Datetime: Thu, 28 Oct 2021 06:47:59 GMT
and it should have a Link header to restate the URI-R:
Link: <https://www.youtube.com/watch?v=7GhO2lncvBg>; rel="original"
That way tools will know it's a memento when they encounter it. See:
https://github.com/oduwsdl/Memento-aware-Browser
& the first presentation at:
https://github.com/oduwsdl/2021-research-expo/
Looking at:
https://ghostarchive.org/archive/mXi9j?kreymer=true
it looks like you're using https://replayweb.page; it *should* have Memento support, but I don't know enough about it to say. If it can't set HTTP response headers, at the very least it should be able to set HTML meta http-equiv="..."
As for mixing images (screenshots) with HTML, the Memento protocol doesn't say anything about it. My personal recommendation is to just mix images & html at this point; you can always split them out later. There are some proposals to specify the difference (mime type is probably not be sufficient), but nothing has been definitively chosen.
Please let me know any questions you have -- I promise I won't wait so long next time ;-)
regards,
Michael
