There's a strong blur between HTTP (HyperText Transfer Protocol) 
and HTML (Hypertext Markup Language) happening, and I am concerned 
that a similar blurring may be happening between LDP and LD (whether 
expressed as Turtle or otherwise).

For instance --

That's completely inaccurate.  Unless you substitute HTTP for
HTML.  But that substitution isn't valid throughout the thread
nor post from which I pulled this snippet.

If we cannot even keep relatively well understood things like 
HTML and HTTP distinct, how are we to do so with new things 
which we are in the process of defining?

Further, analogizing the new things to the old does nothing but 
confuse, when those old aren't kept clear and distinct.

Validating HTML is *entirely* distinct from determining whether
a server is HTTP-compliant, and vice versa.  A fully-compliant
HTTP server *may* not deliver *any* HTML content!

Validating Linked Data is and should be distinct from determining 
whether a server is LDP-compliant, and vice versa.  

(That said, LDP might require that LDP servers *generate* some LD, 
and the validity of *that* LD *may* be relevant to determining its 
overall compliance with LDP.)

Regards,

Ted
