+I think we should agree on an HTML attribute for pointing to the Nostr representation of a document/URL on the Web. We could use the existing one for link relations for example. Something like:
+
+```html
+<link rel="alternate" type="application/nostr+json"
+      href="nostr:naddr1qvzqqqr4..."
+      title="This article on Nostr" />
+```
+
+This would be useful in multiple ways:
+
+1. Existing Web publications can retroactively create Nostr versions of their content and easily link the Nostr articles on all of their existing article pages.
+2. Nostr clients, when fetching meta/preview information for a URL that is linked in a note, can detect that there's a Nostr representation of the content, and then render it in Nostr-native ways (whatever that may be depending on the client)
+3. User agents, usually a browser or browser extension, when opening a URL on the Web, can offer opening the alternative representation of a page in a Nostr client. And/or they could offer to follow the author's pubkey on Nostr. And/or they could offer to zap the content.
+4. When publishing a new article on Nostr, authors can share their preferred Web URL everywhere, without having to consider if the recipients' clients support Nostr IDs and content or not. This makes it easy for the reader to share the author's preferred Web URL on any medium, instead of sharing a link to whatever their own Nostr client prefers (usually its own Web UI).
