Hi Ruben,

Certainly a great idea.

Do  we need to stop at RDFa? Fundamentally, use of <script/> for
embedding structured data islands in HTML is a new pattern that should
be added to the Linked Data deployment mix. This pattern has been widely
adapted by sites that publish structured metadata using JSON-LD and
terms from the schema.org vocabulary [1][2][3].

As an example, our Structured Data Sniffer [4] browser extension doesn't
have a preference with regards to HTML+RDFa, HTML+Microdata,
HTML+JSONLD, HTML+Turtle, or raw Turtle, JSON-LD, RDF-XML. In addition,
it also includes the ability to query pages that adopt any of these
patterns too :)

BTW -- I was actually going to make a demo using your page but I hit a
TLS issue that can be recreated via:

curl -kIL https://ruben.verborgh.org/
