NIP-21 - nostr: URI scheme

nostr: URI scheme
draft optional
This NIP standardizes the usage of a common URI scheme for maximum interoperability and openness in the network.
The scheme is nostr:.
The identifiers that come after are expected to be the same as those defined in NIP-19 (except nsec).
Examples

Linking HTML pages to Nostr entities
<link> tags with rel="alternate" can be used to associate webpages to Nostr events, in cases where the same content is served via the two mediums (for example, a web server that exposes Markdown articles both as HTML pages and as kind:30023 events served under itself as a relay or through some other relay). For example:
<head>
<link rel="alternate" href="nostr:naddr1qqyrzwrxvc6ngvfkqyghwumn8ghj7enfv96x5ctx9e3k7mgzyqalp33lewf5vdq847t6te0wvnags0gs0mu72kz8938tn24wlfze6qcyqqq823cph95ag" />
</head>
Likewise, <link> tags with rel="me" or rel="author" can be used to assign authorship of webpages to Nostr profiles. For example:
<head>
<link rel="me" href="nostr:nprofile1qyxhwumn8ghj7mn0wvhxcmmvqyd8wumn8ghj7un9d3shjtnhv4ehgetjde38gcewvdhk6qpq80cvv07tjdrrgpa0j7j7tmnyl2yr6yr7l8j4s3evf6u64th6gkwswpnfsn" />
