[#]GlobalTalk chatter: what’s the AppleTalk equivalent of URLs?

On the Internet, we can use URLs like

ftp://user:password@server.example.com/path/toshare

to describe the location and type of a resource.

What’s the AppleTalk standard style for addressing, say, folder x, in folder y, in share z, on server a, in zone b, over protocol c?

user i and password j optional.

Old school style guides may need to be consulted.

Was there a standard? I have vague memories there was, google-fu failing.

@europlus AppleTalk really only specifies how to find a service via NBP: object:type@zone. AFP and PAP services define a specific URL format for AppleTalk-based shares which might be what you want. See Appendix A of the AFP client documentation: https://cdn.preterhuman.net/texts/computing/macintosh/AFPClient.pdf

@_the_cloud Thanks, that’s useful - I saw the NBP format as well, but it didn't feel descriptive enough for what I want, so the (extended) URL you show is likely to be what I’ll use (well, without username and password, just like what is on Wikipedia AppleTalk page, too).

I thought there was something that used something like the NBP base to expand further to paths, etc.

But it appears that as a large language model, I may be hallucinating.

@europlus I had a look at the AFP spec in Inside AppleTalk 2nd Edition, and it's not a simple string; you need a dynamically obtained vol ID and a set of null-separated path components. As an experiment, I made an alias to a file on an AFP share in Finder and inspected the contents of its 'alis' resource. No URLs, but the server name and zone are in there, along with a colon-separated path on the server volume.

@_the_cloud Hmm, I might do the same, unless you save me the bother by posting a screenshot 🤣

@_the_cloud scrub that lazy request - I already had an alias to a share, so I looked at it and can see what you mean. I’d need a TMPL for “alis” resources to get a more human-friendly view.

@europlus There's a lot of data in the resource, including file type and creator, and the server and zone strings look like they're maintained separately in fixed-size Str31 buffers. Not sure it's a useful example since it seems to be an internal Alias Manager data structure.
