Hi !
first I would like to thank Thomas Russ for his response but I do not find the right process to solve my problem.

In fact, once the ontology is developed using protégé I need to export 
it as N-Triple in order to load it in an Oracle database (for managing 
many instance in another system based on the Ontology).

the process followed within Protégé is "File -> export to format -> 

However, in the N-Triple file the imported ontology only appears as

<owl:Ontology rdf:about="">
    <owl:imports rdf:resource=""/>

Is there another way to export the whole ontology (local and imported 
ones)  to N-triple format  for retrieving all the concepts  (local and 
impported ones) in the oracle database ??

Thanks in advance
