What I want to do with RDF
Some of the tasks I want to accomplish with RDF, in no particular order.
Keep track of the relationships between characters in a novel, movie, or role-playing game. (FOAF?) Maybe I will finally figure out who shot Mr. Burns.
Create or query for NPCs with some stated constraints, such as “a level 4 character with the Quick Draw feat and at least 5 ranks in the Tumble skill.” (OWL or SPARQL) A good random character generator. No, really.
Represent the semantics of a snippet of Python code with OWL. Generate Python code from an OWL Full description (since both Python and OWL Full allow classes to be treated as instances). Because I am a geek.
Generate human-readable RPG rules from RDF. I can now find and eliminate contradictions in the rule sets before publication.
Write a reasoner that can play a card game like Rokugan, with each card and its rules represented in RDF. No longer do I have convince my wife to play.
Encode enough semantic meaning into a screenplay that I can change any detail about a character and have all dialogue and descriptions reflect this. This will of course displace the standard Hollywood script writer, especially when the program is smart enough to handle replacing a human character with a talking dog.
