Idk, those two terms are as different to me as URL vs URI. Searching it will yield a long explanation about the differences, but IRL people will use them interchangeably.
People do this a lot, but those of us who actually do the work instead of sit and talk in meetings about the work know that there is a huge difference between writing React components (UI) and designing flows in Figma (UX).
It's just outsiders who say UI/UX as if they are the same thing.
I'm a backend SWE. How are those two roles not just UI designers and UI SWEs? Or frontend as our team would say. I get that "experience" suggests something grander than "interface," but that sounds like how I call myself a SWE just to sound better than programmer (which nobody calls themselves anymore, so there's no real difference). Maybe instead of backend we can say "cloud-end" cause "RESTful JSON API" lost its zing.
Writing React components -- frontend engineers (no "UI").
Designing flows -- UX (no separation on UXD/UXE, and they actually have to sit in meetings a lot, to figure out what users want and how others do it).
And we use "UI" for folks in design industry: images, colors, fonts, look-and-feel, modern fashion, transition animations, etc. Maybe some nice interactivity that UX didn't care enough for.
It might seem that way to you, as a url is a subset of uri.
I've never actually been in a company that has UX engineers though. It's usually UX or UX designers which work with figma or similar tools and delegate the coding to non-specific software/frontend engineers
I think it's not a strict subset, there are URIs that aren't URLs (like ISBN numbers), but there are also URLs that aren't exactly URIs, like http://example-blog.com/latest
But in practice, sure, the 2 are pretty much used interchangeably
edit: Perhaps I'm wrong, all resources I can find classify all URLs as a type of URI.
Maybe my understanding of URIs is flawed then, but from your example it looks like an URI for blog articles sorted by publishing date. List<type> was a valid resource type as far as I remember.
