Hi - could you print the data in a readable syntax such as Turtle? and a
complete, self-contained example?
The list occurs at:
<http://mycompany.com/data/bp-2/b-7406478b-9c33-4b51-bb46-3b854fc633cd>
<http://mycompany.com/data/bp-2/batch/companyIds>
( 136648473 136648520 136648577 ) ;
in the object position.
val rec = sol["x"]
?x is a subject.

Hello!
I have a Jena-based database with an individual batch in it. A batch is a
structure, which has (among other things) a list companyIds (elements are
strings). In this particular example the batch number 1 has a list with
following company IDs:
136648473
136648520
136648577
My goal is to retrieve this list. For this, I execute the following code:
open fun batchStatusLogic(ds: Dataset, batchId: Int):
FailableOperationResult<Bp2BatchStatus> {
val sparql = """SELECT ?x
WHERE { ?x <$Bp2BatchNumber> $batchId }"""
val query = createQuery(sparql)
val qexec = createQueryExecution(ds, query)
val rs = qexec.execSelect()
if (!rs.hasNext()) {
return FailableOperationResult<Bp2BatchStatus>(
false,
"Batch not found.",
null
)
}
val sol = rs.nextSolution()
val rec = sol["x"]
val prop = findStatement(Bp2BatchCompanyIds, rec as Resource)
if (prop == null) {
return FailableOperationResult<Bp2BatchStatus>(
false,
"Company list not found.",
null
)
}
val obj = prop.`object`
if (!(obj is RDFList)) {
return FailableOperationResult<Bp2BatchStatus>(false, "Internal logic
error.", null)
}
obj is not RDFList, but ResourceImpl with obj.enhGraph being displayed as the
XML given below.
How can I read all elements of the list (136648473, 136648520, 136648577) ?
If there is a problem with the way the list is stored, please also tell.
Thanks in advance
