[tantek] The GUID thing that is supposedly "one thing that I feel like RSS and Atom still do better than h-feed" I've literally NEVER seen actually work in practice (with RSS/Atom feeds).
#
[tantek] and by work, I mean, someone actually comes up with a workable maintainable GUID scheme for their posts, then changes domains/permalinks, and their GUID system keeps working
#
[tantek] As you say [fluffy], feeds that bother with GUID typically re-use a permalink URL, maybe without optional slugs (so permalink slugs can be edited without altering the GUID)
[fluffy] joined the channel
#
[fluffy] I’ve changed post categories on my site many times and the GUID follows the post and people don’t get re-notified of a new post, so
#
[fluffy] even when the post URL changes
#
[tantek] post categories?
#
[fluffy] yeah like moving from /blog to /articles or whatever
#
[tantek] do you put your categories into your permalinks?
#
[fluffy] yes
#
[fluffy] permalinks will also chase redirects too
#
[tantek] ah got it. in that case, well done! [fluffy] ++
#
[fluffy] but like also the title slug is part of it so fixing a typo means changing the URL too
#
[tantek] that's what I meant about the slug above
#
[fluffy] right
#
[fluffy] anyway my point is that Publ very specifically generates a GUID that sticks to the entry regardless of how the permalink changes
#
[tantek] I've considered at some point generating GUIDs that only use my slugless permalinks for this reason.
#
[tantek] though this is more of a #indieweb-dev chat
#
[fluffy] but the GUID never appears in the URL, and there isn’t even any publicly-visible way to query an entry URL from a GUID (although I’ll want to add that at some point, probably when I implement native activitypub, so it just hasn’t been a priority)
#
[fluffy] yueah
#
[tantek] the mf2 question, p-* properties should work on (nearly) any element and "do the right thing" for that element
#
[tantek] for simple "property/value" handling
#
[fluffy] Yeah, maybe the docs should be updated to indicate that it should be u-uri if the GUID is a URI and p-uri if it’s an opaque string
#
[tantek] u-* tells the parser to do URL specific handling, preferring URL specific attributes, and doing relative URL resolution
#
[fluffy] er, u-uid and p-uid
#
[fluffy] I do know that u- and p- are the data type and then the name is actually ‘uid’ but my brain always has trouble connecting those two facts when I implement something 🙂
#
[tantek] it hasn't so far because we haven't had any actual working examples of opaque string GUIDs
#
[tantek] no, not data type
#
[tantek] that's part of the confusion here
#
[fluffy] well we do now 😉
#
[tantek] the prefixes are parsing instructions
#
[fluffy] see https://beesbuzz.biz/blog/
#
[tantek] right, so next step #indieweb-dev, and adding examples to indieweb.org/uid

#
[KevinMarks] Do you use the guid as the etag too?

#
[fluffy] Was that question for me? No, I compute the etag from the content hash.
#
[fluffy] Or rather the full rendered page’s hash.
#
[KevinMarks] that makes sense, yes
#
[KevinMarks] content hashes can be cross-site guids if you're careful about relative URLs
#
[fluffy] Like I don’t want the page ID to change every time I fix a tpyo, and I also don’t want caching to completely break whenever a prev/next link or “12 hours ago” or whatever changes.
#
[fluffy] Basically, I only implement etags for the sole purpose of cache control.
#
[fluffy] And any further discussion of this is #indieweb-dev of course.

@sheldon_hull ↩️ Well it worked with bridgy. Will have to look further as microformats and presenting it a bit confusing. (twitter.com/_/status/1393651926022111234)
