is u-category a thing that gets used? or should i stick with p-category?
#
ulhar4409
actually, u- would probably imply that the parser should look for a link and treat that as the primary value, which feels probably wrong

It depends on the type of post and context, what you intend consumers to see. In most posts, if you want a tag/category name to be the result, you want p-category. Some indieweb cases like people tagging use u-category, though: https://indieweb.org/person-tag#How_to
#
ulhar4409
my current plans are basically just category "names" that happen to link to a page with more in that category
#
ulhar4409
although, if the link points to another website entirely with the intent of being a submission for *that* site, would that be a good usecase for u-category?

you can put rel="tag" if it links to a tag page, that's the previous model. Are you sending webmentions to *that* site?

if it's not a same-site page then i would

chances are slim the external site is parsing microformats, so probably still p-category
#
gRegor
If they receive webmentions, they'll be verifying the link appears on the page, not looking at the mf2
#

~~Not if I also make the external site~~
#
gRegor
What would be your consuming use case for u-category then?
#
ulhar4409
i do have an idea for an opt-in tagging site, that would accept webmentions on its tag pages and interpret successful mentions as submissions
#
gRegor
p-category would still work for that
#
ulhar4409
yeah probably
#
ulhar4409
i guess it's a question of "is the URL or the name more useful? "

Worth checking out IndieNews an indiewebxyz, they didn't use p-category quite like that, though they could. A syndication link like IndieNews uses works to establish the intent to submit the post
#
gRegor
and a category name (hashtag) would be sufficient for categorizing it in the aggregator
#
ulhar4409
oh true, i kind of forgot about syndication links
#
ulhar4409
there is a sort of "remarks in tags" pattern from tumblr/cohost that i would be wary of here, which could probably be sidestepped with some kind of "Please don't p-category your tags if you're not using them as categories" policy
#
ulhar4409
idk if i need to dig into that project right now anyway
#
gRegor
yeah, tag moderation is something to definitely consider

this is getting more into #indieweb-dev though :)
