RDF Model Namespaces

[Pastrana, Rodrigo (RIS-BCT)]

I'm new to Jena RDF API and I'm noticing some unexpected behavior regarding 
statement namespaces...
I've noticed that URI resources such as  
"http://www.govtrack.us/data/photos/412483.jpeg"; in the below excerpt of the 
congressional people graph(http://www.govtrack.us/data/rdf/people.rdf.gz)
Are reported to have namespace: " http://www.govtrack.us/data/photos/410069."; 
And local name "jpeg" using the com.hp.hpl.jena.rdf.model.Resource 
getLocalName(), and getNameSpace().
Is this correct behavior? It looks to me like the dot is being used as a 
delimiter between the NS and the local name. Is there a way to change that 
behavior ? thanks!
