Do you mean integrate only the SPARQL-part or the whole? I agree to the
first statement :) but the other wikidata specifics are perhaps better
kept on its own.

Actually the endpoint is a Blazegraph-server and my get-query code does
not seem to work right (see the bug mentioned in the latest commit).

Does guile-sparql work with Blazegraph? If yes we don't need the (buggy)
sparql-get-query-code I wrote.

I could not get it to work and rolled my own as a teach-yourself-scheme
learning-by-doing pet project :) 

I tried with the file attached but got this because the driver does not
support URIs but only host, port, type, token:

In web/client.scm:
    461:0  2 (http-post "http://…"; …)
    181:7  1 (open-socket-for-uri _)
In unknown file:
           0 (getaddrinfo "http" "http" 0 #<undefined> #<undefined> #)

ERROR: In procedure getaddrinfo:
In procedure getaddrinfo: Name or service not known

Thanks for the tip :)

Additionally I have a suggestion for guile-sparql. Could you generate a
pdf from the texi-manuel and include in the repo?
