Re: Retreiving instances of concepts

[Young]

Hi,

 I have created an ontology and would like to retrieve the instances of the concepts, so that i may visualize in tabular form or web -mapping aplication. I have just started reading java for beginners, so to Jena. How else can i solve this without writing a program?

 

Please help

Well, it isn't clear to me how you would get the information you want  
to use in a program without programming, but....

You could start by looking at the Queries tab in Protege.  Maybe what  
it lets you do is sufficient?  You can export the query results to a  
file.

I am not sure what you are asking here.  If you are trying to build custom web pages that retrieve instances from concepts, you are probably going to need to write a program.

To do what you are trying to do you are going to have to learn several technologies (minimally Java, servlets, and some owl api but it sounds like you will also need some graphical web toolkit).  The owl api is probably not the biggest hurdle.  One of the things you will need to do is select the owl api that you need to use.  Jena is a fine choice.  If you are just working with owl files I usually prefer the owl api (owlapi.sourceforge.net).
