Ninus; A triple store is similar to relational database, as it is an application whose sole purpose is to store and query data. The difference is that the conceptual representation is in RDF graphs instead of the relational model.
Just as the relational model has a query language, SQL, RDF graphs have a query language - SPARQL. SPARQL supports SELECT and CONSTRUCT. Composer extends that to include <(select ,insert, update, delete)>, where update (MODIFY) is performed through insert/delete pairs. That should be the first step into getting data out of an ontology, and manipulating it. Inference profiles (RDFS, RDFS+, OWL, OWL RL, etc.) are specialized kinds of query/insert for triples in which an ontology must be carefully designed to support the inferences . It has interesting uses, but is limited to what these profiles define. SPARQL significantly extends what can be done with these and Composer's SPIN turns SPARQL into an inference tool. <sparql to (insert and delete) triples> Absolutely. I'd suggest starting there and move to <tableau reasoners, axioms, non-trivial inferences> if you really need them (you may not). -- Scott On Mar 26, 9:53 am, Nick Khamis <[email protected]> wrote: > Hey David, > > Right now the whole tripe store thing is a blur to me, maybe you can add > some focus to it clarifying my areas of void or misunderstanding. > > Let take to traditional software applications using RDMS: > Implement an application that creates RDMS database schema (create tables, > foreign keys, primary keys blaaa), and stores data to the database using SQL > (select ,insert, update, delete)...
