All, I know this is not a new topic, so hopefully there is a reference to the de-facto standard answer on this (that I have not been able to find on my own so far).
When I have a Subject that I want to store additional information about, I can just add triples using the same Subject. Easy. When I want to say things about a Statement (such as the date range within which the triple Statement is valid, or the strength or source of the relationship), the answer is more ambiguous. Reification is the standard answer, but it is also heavy. I've read about using Quads, Named Graphs, N-ary Relationships, etc. What is the current state of the art or best practice in this regard?
