Parsing error in my graph stating that content is not allowed in prolog

Question

I just inserted the following graph:

@prefix : <http://buchmann.ro#>.
@prefix xsd: <http://www.w3.org/2001/XMLSchema#>.

:moviesInfo

 :hasName "California"@en, "Californie"@fr.
   :Austria         :hasName "Austria"@en, "Autriche"@fr.
   :USA     :hasName "United States of America"@en, "Etats Unis d'Amerique"@fr.
 }

My problem is that I tried to introduced many times into the GraphDB, also tried to parse differenty, but I got the same error:

RDF Parse Error: Content is not allowed in prolog. [line 1, column 1]

I am trying to learn RDF again, so I am very beginner, but trying my best. Thank you!
