Conclusions

The project was started with 3 questions.

The answer is positive on all three.

• Yes, it is possible to get an idea of the content of a store. But you need to know some things. For instance, that the rdf:type predicates are (in our case) almost always pointing to an object. This means the expansion mechanism ‘incoming arcs’ must be used to find instances of a class. So, this still requires a basic understanding of RDF. If a reverse predicate (for example, has-instance) were available, the discovery would be much easier.

• Yes, it is possible to create an editing tool for RDF stores.

• Yes, Emacs can be used for this. In fact, for the quick development of something where the entire functionality cannot be determined, the malleability of Emacs helps a lot in developing something like this.
