RDF - more than one object for one object-object

Question

I have one (maybe) simple question: can I assign more than one ObjectResource to a fixed Subject-Property statement?

I want my RDF triples to look like this:

[http://somewhere/Angela_Merkel, http://somewhere/properties#isMentionedIn, http://somewhere/New_York_Times]

[http://somewhere/Angela_Merkel, http://somewhere/properties#isMentionedIn, http://somewhere/The_Guardian]

[http://somewhere/Angela_Merkel, http://somewhere/properties#isMentionedIn, http://somewhere/BildZeitung]

etc. Is this rdf formed correctly?

And can I implement this in Apache Jena?

Answer 1

Yes, that would be well-formed data, and this is a general way of defining multiple values ​​for a given property for a given object.

RDF has very few restrictions on which three you can declare. Essentially, it boils down to the following:

• Subject must be URI /? blank node
• URI
• URI/blank node/literal
• , ..
