Hi all,
Recently on this list I saw discussion of a SPARQL validator endpoint in
Jena/Fuseki, but I think I've deleted the emails as I can't find it now. Can
someone please point me to the Jena/ARQ docco about SPARQL validation and, if I
have this right, info about online validation endpoints using that tool?
I can find the instance online at https://sparql.net/ and the similar looking,
but non-functional
one at https://linked.bodc.ac.uk/validate/query. They say they are using "Apache
Jena Fuseki".
And the pages are Fuseki-ish.
https://sparql.net/ (or .org) is kept up on a "best effort" basis only.
It's a single VM. Sometimes it gets overloaded by accidiently DOS
Website Pages:
https://github.com/apache/jena/tree/main/jena-fuseki2/jena-fuseki-main/sparqler
Code:
https://github.com/apache/jena/tree/main/jena-fuseki2/jena-fuseki-core/src/main/java/org/apache/jena/fuseki/validation/
So is this an older, or optional, version of Fuseki? Can I turn one on with
current Jena/Fuseki?
It (SPARQLer) is available in Fuseki/main, use "--sparql=HTMLfiles" -
that loads the validators as servlets under /$/ and is what
https://sparql.net/ is running.
We have a need to validate SPARQL queries, reformat them and, as per recent
discussion here, inject things into slots in queries.
Thanks, Nick
