Hi Kingsley,

> That is too broad a claim to make.

You're right, I should've been more exact.
I use the word "queryable" in the wrong way;
everything is queryable, sometimes with zero results.

With the statement

>> I have provided one simple way for my own website
>> to make itself queryable, i.e., a TPF interface instead of LD documents.

I mean the following:

If one wants to evaluate a SPARQL query
with full completeness with respect to all data on a given website,
then LD documents cannot provide that for all SPARQL queries.
This requires different interfaces,
such as a data dump, SPARQL endpoint, TPF interface, 

For an example of completeness differences, see:
https://ruben.verborgh.org/articles/queryable-research-data/#queries

> You can build applications today that use Web Pages as structured data sources.

Yes, but only those that crawl all pages
will be able to guarantee full completeness
with regard to the entire website.

Best,

Ruben
