[Pre-RFC] DNS domains as package namespaces

jmillikin:

what you're describing here is something like a reserved prefix

What is a namespace if not a reserved prefix. I was primarily referring to why use a domain and not an existing crate. In your Cranelift example cranelift.dev/simplejit you used a domain, even though the project already has a "parent" crate that could be used, thus becoming cranelift/simplejit, without having separate ownership/naming sources like domains.

On your serde example there already is a main crate serde, that can be used as the namespace, possibly with a serde/unofficial/foo, thus still having everything bundled under serde.

And on your fuse/sane/sleigh example: Still possible. The main downside is that your (arbitrarily chosen) namespace must not conflict crate names (and will mean you can't publish a crate named like your namespace in the future unless it is put under a different namespace).

The effect is the same, except that each existing crate automatically gets a namespace and there are no problems with domain expiry.

Technically nothing would prevent us from having both crate names and domain names as namespaces, as long as crate names cannot contain a '.' and you can't use the TLD itself:

foo
example.com/foo
serde/foo
