There is no connection between using a URI and a file. That is just a string used as a URI. If you change it ... you don't get "file not found"

* String fullName = "rohit kumar";*
*// create an empty Model*
*Model model = ModelFactory.createDefaultModel();*

Empty model.

*// create the resource*
*Resource res1 = model.createResource(personURI)..addProperty(VCARD.FN,
fullName);*

What happens after this code? Is this save "rohit kumar" in the file
std.rdf?

No.

read the file into a model (RDFDataMgr or model.read), change it, write it out again.

See the tutorials.



I can not find this resource after running this code and open the file in
Protege?
