I've created an ontology with several instances. What I'm going to do with it is :
Using Eclipse, create a searching program. User can input a string, and if an instance has this string as one of its datatype properties, the name and other properties of this instance will be shown to the user.
I really have no idea what plug-ins of eclipse, what grammar, or what other tools I should use. I'm extremely new to semantic web and the relevant tools, so any help will be great. Thank you so much!
You could look at the OWL-API as a starting point for using ontologies in a programmatic fashion. It shouldn't be a problem to integrate it with other Eclipse tools.
