Sorry, now it's clear.
AFAIK internally
1000
and
"1000"^^xsd:integer
are the same.
What you ask is a feature of the Turtle Writer.
You should look for settings of the Turtle Writer, if any.

It does that.  N-triples does not, nor does RDF/XML.


If Jena does not do it,
look for another tool like rapper, Euler/EYE, etc.

Yes - it's a syntax feature of Turtle that xsd:integer can be written 
that way. Same with xsd:decimal (if there is a dot)

xsd:int and other derived types can't - it would loose the detailed type 
information.

Jindřich - do you have a detailed example?

Hi Jean-Marc,

I'm aware of createTypedLiteral, but I don't want to generate typed
literal, but a plain one instead, as I have indicated in my question.

For example, 1000 instead of "1000"^^xsd:integer.

Hi,

can I use Jena to create non-string plain literals, such as integers?

ResourceFactory.createLiteral() (



https://jena.apache.org/documentation/javadoc/jena/org/apache/jena/rdf/model/ResourceFactory.html#createPlainLiteral-java.lang.String-
)
is available only for strings.
