Re: [Virtuoso-users] Library to parse SPARQL queries
Hi Lorenz,
In fact, we also need to parse the queries because we need to get Expr,
Triple, etc. from the queries. We've augmented the queries based on Expr
and Triple. Do you know how to overcome this? Thanks a lot!
Best regards,
Kinh

Hi Lorena,
Thanks Lorena. Indeed, this Javascript library seems so powerful. I
just
had a quick look and found that the library also supported 'IN'.
However, sorry to not mention in the first message, I'm actually using
JAVA. Does you know a solution for this?
Best regards,
Kinh

Re: [Virtuoso-users] Library to parse SPARQL queries
Hello Cong,
the problem is that the first query is illegal SPARQL Syntax, but
Virtuoso allows such queries nevertheless.
You can avoid the parsing to a Query object if you use the
QueryEngineHttp class instead, which only works with the query string
and does not do any syntax checks.

Re: [Virtuoso-users] Library to parse SPARQL queries
Hi Lorena, Lorenz,
Thanks for your information. Sorry, I didn't check carefully the
documentation about SPARQL1.1 before picking an example 'IN' in the
SPARQL. Basically, we've created restful service for augmenting SPARQL
queries. The queries are created by third party and sent to the rest
endpoint to execute. The queries could be successfully run with SPARQL
endpoint of Virtuoso. However, our Restful endpoint was failed to run
such queries. The root cause was that Apache Jena library didn't
understand the queries sent by third party. I just tested a real case we
already had:
select ?s as ?s1 ?p ?o
where {
?s ?p ?o
}
limit 100
This query is very simple, okay with Virtuoso, but failed with Apache
Jena. For Apache Jena, we need to do something like:
select (?s as ?s1) ?p ?o
where {
?s ?p ?o
}
limit 100
But, basically SPARQL queries are sent by other people to our Restful
service, they just test the queries with SPARQL endpoint of Virtuoso,
then they expected it would work with our Restful service. Does anyone
of you know any possible solution for our issue. Thanks!
Best regards,
Kinh

Re: [Virtuoso-users] Library to parse SPARQL queries
Hi Kinh According to the info on ARC site it seems to support SPARQL 1.1. IN clauses are part of this standard, so it should be supported.
