Derefrencing URI
I want the rdfs:comment of European capital cities in one file using Jena.
While studied a lot about it, I still have no idea how to do this. I can do
it of individual resource using Virtuoso but combining these into one file
using Jena is currently beyond my knowledge.
Also what is Dereference URI to RDF?
Kindly if some one can help me here.

For the _last time_, please give some actual examples of your data. This mailing list does not permit attachments. Use a paste service or put an extract in your message. Also give the code you are trying to use.

Hi
A general way of extracting parts of an RDF file into a new file is to use Jena to:
- Load the file into a model
- Run a CONSTRUCT SPARQL query
- The query returns a new model
- Write the new model to file
Dbpedia has a sparql endpoint, so if you need to query dbpedia from your own SPARQL query, you can use the SERVICE keyword.
If you are unfamiliar with the CONSTRUCT or SERVICE keywords, then look at these
- http://www.w3.org/TR/sparql11-query/
- http://www.w3.org/TR/2013/REC-sparql11-federated-query-20130321/

Hello Soroka thanks for your reply.
Actually I know these basics. I have read the owl file in Jena, run SPARQL,
execute it and display the question/answers(required output).
What I need is to download/show the rdfs:comment or rdfs:abstract of the
ten resources(ten cities of Europe Berlin, London) from dbpedia in a
page/document .
Can I do it if I hard code them in the rdfs:comment in Protege with each
question and display it along the answer of the question?

If you have not written any Jena code than you should begin with the tutorials provided exactly for that purpose:

Dear Soroka, I do not know how to use Gist etc but if this mailing list
support attachment , I can attach the owl file.. Jena code, I did not try
it because I am totally clueless how can I do it?
In one statement, my question is can I get rdfs:comments of , say ten
resources, of dbpedia using Jena methods?
Thanks.

No, please provide _actual data_. You are describing your data in words. That is not helpful. Make your OWL data available somewhere using a service like Gist or at the very least, include an excerpt. Also please include the code you have written so far.

I am working on undergrad project. The detail is I have owl file where I
included ten questions about European cities like Born city belongs to
which country? The resources/answers are imported from dbpedia in Protege
Individual tab. I then used Jena API. The questions/answers work fine.
The point where I have problem is I want a document/file etc where I
include the rdfs:comments or rdfs:abstract of these cities so that the
users knows about the resources.
I mean when users finishes all the ten questions, at the end he/she gets
rdfs:comment details about these resources in a document or so.If this is
not possible, then please suggest me some soloutions which is near to it.
I hope I conveyed my message?
