I read bishop Claire participation 2006 the poetics of open works, and summarised what I learnt into a few points.
1) A piece of work can be open and closed, closed because it's complete and got a certain origin but open in the sense that it's open for interpretation from the audience with infinite outcomes.
2) openness is where a piece of work is not defined by a fact and infinite in its direction.
3) closed, is where it's a command or instruction only one definition or interpretation, it's factual based.
4) open and closed contradict each other but also is considered as complimentary.
5) contempary work is open, older work like avant garden is normally closed.
