↳ In-reply-to » Trying to wrap my head around webfinger..

@xuu@txt.sour.is that doesn’t seem to fit the spirit of the spec, at least by my read (I could be wrong obv). The example on Wikipedia’s webfinger page,

{
	"subject": "acct:bob@example.com",
	"aliases": [
		"https://www.example.com/~bob/"
	],
	"properties": {
		"http://example.com/ns/role": "employee"
	},
	"links": [{
			"rel": "http://webfinger.example/rel/profile-page",
			"href": "https://www.example.com/~bob/"
		},
		{
			"rel": "http://webfinger.example/rel/businesscard",
			"href": "https://www.example.com/~bob/bob.vcf"
		}
	]
}

and then the comparison with how mastodon uses webfinger,

{
    "subject": "acct:Mastodon@mastodon.social",
    "aliases": [
        "https://mastodon.social/@Mastodon",
        "https://mastodon.social/users/Mastodon"
    ],
    "links": [
        {
            "rel": "http://webfinger.net/rel/profile-page",
            "type": "text/html",
            "href": "https://mastodon.social/@Mastodon"
        },
        {
            "rel": "self",
            "type": "application/activity+json",
            "href": "https://mastodon.social/users/Mastodon"
        },
        {
            "rel": "http://ostatus.org/schema/1.0/subscribe",
            "template": "https://mastodon.social/authorize_interaction?uri={uri}"
        }
    ]
}

suggests to me you want to leave the subject/acct bit as is (don’t add prefixes) and put extra information you care to include in the links section, where you’re free to define the rel URIs however you see fit. The notion here is that webfinger is offering a mapping from an account name to additional information about that account, so if anything you’d use a "subject": "acct:SALTY ACCOUNT_REPRESENTATION" line in the JSON to achieve what you’re saying if you don’t want to do that via links.
