The serialization context I'm interest in is org.apache.jena.query.ParameterizedSparqlString (toString(): https://github.com/apache/jena/blob/master/jena-arq/src/main/java/org/apache/jena/query/ParameterizedSparqlString.java#L1291-L1377). I probably should have clarified that before.
However, I just noticed that if the xsd:integer datatype is provided explicitly, then it is serialized as a plain literal: ResourceFactory.createTypedLiteral(1000) => "1000"^^< http://www.w3.org/2001/XMLSchema#long> ResourceFactory.createTypedLiteral(1000, XSDDatatype.XSDinteger) => 1000 This solves my issue.
