How do people go about mapping their existing data into an ontology? I must be missing something very basic here.
I have identified an OWL ontology that (for the most part) covers the data in my database but I am confused as to how to build the triples. Is this normally a manual process? Should I be writing code to run through my existing data and build the triples one by one or are there tools out there to do this type of thing?
I keep thinking that I should be able to find something that lays out my ontology (i.e. Protege) on one side and my db schema on the other and let me connect the two to generate the triples.
Can someone point me to any reference material in regards to how to do this as my head is killing me from banging it against this wall.
