I have written a rough document considering several aspects of the SDD-schema - largely interpreted with reference to our Prometheus Database model for descriptive data. It seems easier to keep this all together, rather than post it to various sections on twiki, so i am attaching it here

My main problems in interpreting the schema were the lack of documentation ( as always...) especially for the conceptually complex parts like concept trees. I think clear, visual summary models for description, characters, concept trees etc would help a novice to get to grips with the concepts, and might make some of the complexities more tractable. I do worry that the overall schema is over complex and 'trying to do too much in one go' - eg considering multiple language and expertise representations, although I am sure that there are good political reasons for everything.....
