citation?

There are lots of tools which support Turtle, and some people find it easier to read and write by hand than RDF/XML.

No software which supports Turtle is meant to be supporting that and *not* RDF/XML, given RDF/XML's position in the specs…

At the same time, implementers will support other schemes and bridge to HTTP. A mailto: or acct: scheme URI will always be a more intuitive WebID than an http: scheme URI.

No. In reality, do this, and somebody will come along with their “WebID verification agent” which only supports their pet scheme, and claim it's perfectly in line with the specs, and the only people who will suffer will be end-users.

Whether the scheme is intuitive or not to write down and remember is slightly besides the point when the only time you see it is when you're publishing it and generating your certificate.


> Turtle has to be there right now. Keeping it out is also kinda contradictory. Remember, SPARQL query patterns used in WebID examples are based on Turtle. Without Turtle we wouldn't have SPARQL. Without SPARQL (albeit an implementation detail) you wouldn't have the exponentially growing Linked Open Data Cloud of today.

It’s not 'keeping it out', but it’s not mandated.

With each that you mandate, though, you’re increasing the burden on implementors, and DECREASING the likelihood that people who build ordinary websites will actually bother with any of it.
