Hi,
I am a beginner for Semantic Web and currently working with JENA. I
came across the attached file FOAFFriends.rdf that could be read into a
Model with the following statement:
private void populateFOAFFriends(){
_friends = ModelFactory.createOntologyModel();
InputStream inFoafInstance =
FileManager.get().open("Ontologies/FOAFFriends.rdf");
_friends.read(inFoafInstance,defaultNameSpace);
}
Also, here the defaultNameSpace is:
static String defaultNameSpace =
http://semwebprogramming.org/2009/ont/chp2#
I have the following question:
The attached file has declarations such as rdf:ID="me". I believe from
my reading that if there is rdf:ID declaration in a RDF document, then
it should also contain xml:base declaration, but the file is missing
this declaration. So, how is JENA successfully able to read the RDF
file? Where does it get the xml:base declaration from to determine the
complete URI of "me"? Does it do something with the defaultnamespace?
If you say defaultnamespace to be the xml:base, then my question would
be that the xml:base should not contain the # symbol at the end but the
declaration here for defaultnamespace does. How do you justify this
please?
A quick reply would be highly appreciated.=
Thanks
With Regards,
Abhishek S
