Re: SWI-Prolog for the semantic web
#2The opening paragraph is structurally identical to "buy our nuclear power plant, it'll generate a billion terawatts, oh and it also comes with this bike shed". Prolog (the submission says) handles the gruesome problem of dealing with RDF, oh and it also generates HTML pages and JSON!
That pattern's a red flag whenever I see it. Like an ostensible proof of P!=NP that begins with a 30 page history written for laymen. Who is that paragraph aimed at? Is there really a sizeable population casually using RDF and Prolog but losing sleep over HTML and JSON?

There are a lot of non-developer types who need to deal with metadata and for whom the mechanics of websites are irrelevant, e.g. scientific researchers or art historians or statisticians.
Librarians invented metadata not computer scientists.

#4SPARQL which is the standard query language for RDF is based on Prolog. So why go back to Prolog?

#5I used to use the swi-prolog semantic web tools heavily. Very good stuff.
The cleopatria semantic web server is interesting, but I have just played with it. The core RDF storage and inference get libraries were solid and nice to use.

Have you met academics?
Just kidding ;), but by exaggerating, not by lying. (Also I know for a fact that you have met academics). Of course any compsci academic can pick-up HTML and JSON in half an hour of time, but it's not mad to imagine that some of them never were interested in actual web technologies (working on RDF can be done from a purely theoretical point of view) and seeing this sentences on HTML and JSON may be a useful information to them, just as mentioning a practical use-case at the end of a paper's abstract can be.

#7How does the closed world assumption of Prolog (if it's not explicitly specified it is assumed false) mesh with the open world assumption (if it is not explicitly specified it is unknown) of RDF?

Prolog is a full programming language, SPARQL is only a query language.

#9It is always nice to see Prolog on the news. SWI was the choosen implementation at my university back in the mid-90's.

In all the practical applications I've seen of RDF or OWL, all the queries rely on some form of the closed-world assumption.
