Hi everybody,
I have been using Jena library to parse SPARQL query. However, Virtuoso
supports a lot more than Jena. Could anyone tell me if there was any
libraries for parsing SPARQL queries with extensible features (for
example: support 'IN', etc.) in Virtuoso? Thanks in advance!

Hi Kinh.
I've been using this javascript SPARQL parser for a while and it's very
good.

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,

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.

Apache JENA supports full SPARQL 1.1 and thus also FILTER IN clause.

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
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
