The src attribute gives the URL of a page that the element's content navigable is to contain. The attribute, if present, must be a valid non-empty URL potentially surrounded by spaces. If the itemprop attribute is specified on an iframe element, then the src attribute must also be specified.

Atproto markup for HTML - byJP
A call to use trivial RDFa markup in our HTML to indicate which records produced the elements on our pages.
Hey #atprotodev; should we make a convention for annotating HTML elements with the AT uris they’re built with? (So that, say, a browser extension could offer links to @pds.ls) Something like this? <li typeof="schema:Thing" resource="at://did:web:example.com/org.example.lexicon/rkey">
got me thinking too, we should create a standard way for standard site hosts to expose embedable content. Maybe an html subset, maybe just an iframe, maybe something else?

What do streets think about being able to read long form content / blogs from within blacksky.community (powered by standard.site) @pckt.blog @leaflet.pub @offprint.app in the below rough demo.
this is also a thing, but separate from the basic website stuff anna is talking about. the at:// potential is sort of about navigating to that sort of URI in browser bar. but I think more realistically, having anchor links. <a atref="at://..."> (or more realistically: data-atp="at://...")
If you're an #atprotodev I'd love your thoughts on this short proposal. I think we'd all benefit from a way to tag our HTML to reference the at:// uris they're derived from! @popfeed.social, @bookhive.buzz, @sifa.id, @leaflet.pub, @pckt.blog, @offprint.app and many more — penny for your thoughts?
