Not sure.
I think it relates to the question Tom is asking.

Another way of putting it is that we don't expect Tabulator to include RDFa
of the RDF we are currently browsing (I think - or maybe we should?).

So I think it comes down the purpose of the exercise, and there is no one
size fits all.

If I have some web pages, then being able to simply embed RDF (by whatever
means), or link to associated RDF resources, is really great. Good for
convenience, maintenance.

On the other hand, if I am trying to simply publish RDF, for example out of
a DB, then things are a bit different. To help people who want to build
agents that use it I might expect them to be able to visualise what I am
publishing by using Tabulator or other tools to browse it generically. Or
equivalently I might provide some human readable pages of the RDF to make my
data more easily accessible.
Because it is a bespoke browser, then I need to add rel link to the RDF URI.
And then someone suggests I should add RDFa or something more to these
pages.
Before I know it, I have invested a lot of time providing (and maintaining)
neatly formatted and RDF-friendly web pages to publish my DB, when all I
wanted to do was join the Semantic Web by publishing my RDF.

In fact, one of the options when Kingsley asked for the rel link was to
simply remove all the html description pages, getting back to the core of
what I want to do, which is publish RDF as Linked Data.
