I have a jsonld representation of triples :

{"@id": "some-id",
    "@type": "Row",
    "attendance": 74439,
    "average_cards_per_match_pre_match": 0,
    "average_corners_per_match_pre_match": 0,
    "average_goals_per_match_pre_match": 0,
    "my_field" : [-0.0368623323738575, 0.06313438713550568,
 -0.05376605689525604, -0.0368623323738575, 0.06313438713550568, -0.05376605689525604]
}

When parsing using rdflib :

g = Graph()
    g.parse(
        data=json.dumps(jsonld_response),
        format="json-ld",
        context={
            "@vocab": "/",
            "@language": "en",
            "rdfs": ";,
        },
    )
g.serialize(format="xml")

The duplicate values of the my_field are removed and only three triples are created in the resultant rdfxml.

<my_field rdf:datatype=";>-0.0368623323738575</my_field>
    <my_field rdf:datatype=";>0.06313438713550568</my_field>
    <my_field rdf:datatype=";>-0.05376605689525604</my_field>

Is there a way to make sure duplicate values are not truncated?

In RDF a statement is either stated or not stated and there is no order of statements. It does not make a difference, whether you state a statement once, twice, … and in which order you state them. If repetition or order of values matters, you can e.g. use an rdf:List. To state an rdf:List in JSON-LD, you can extend the context in your case by:

"my_field": {
  "@container": "@list"
}

This should cause the parser to consider the array values as members of an rdf:List.
