Re: Schedule and Events Conflicts Management in RDF

Hi Karl

In a relational world, conflict is resolved with normalisation,

I was interested to learn that even in the semantic world, normalisation 
exists and functions pretty much the same way

I think the solution to conflict could be instead of cramming everything in 
the same schema, to create more than one primary entity, each entity has all 
the necessary attributes

Each entity/attribution relation can then be viewed/search according to some 
kinf of facets navigation
Movie in my view should be a separate entity (ie movie duration is an 
attribute of movie together with
actors, director etc) while movie viewing time is a different type of 
variable and it should be in a different
'table' (schema?)

Something like
VIEW MOVIES (show TITLE, theater, time)
VIEW cinema (SHOW TITLES, time)
VIEW TIME (whats on today?) (show movie, theater)
etc

something like that

wonder if it would make things better
