Dear Arthur,
Thanks for the prompt answer, I will try. Here, is the ontology as RDF/XML

> There is missing information about object properties. And the link between

> Assuming you are requesting a query to create a triple of type (Ivan, a

>
> INSERT{ ?person isRelatedTo ?city}
> WHERE{
> ?person a Person.
> ?person name "Ivan"^^xsd:String.
> ?city a City.
> ?city name "London"^^xsd:String.
> }
>
>
> where "isRelatedTo" is an object properties of your choice.
> This query will create a triple for each city with a name of London and
> every Person with a name equal to "Ivan".
>
> I hope this will help you. For more information about SPARQL queries I

> It would be much easier to help you with your minimal ontology include in
