The 'sea' of data is huge - I am doubtless entered into it multiple times with all manner of associated data. The ICE casts it's net (with a pack of valid as well as a far number of non-valid associations) through this sea and when it lifts it there are number of 'fish' therein. I will be in there, among the silvery bodies and the attached associations. I am 'by-catch' as I have no crime ever - but millions of tons of bycatch die even if discarded. There is an old French Canadian poem, that says, in essence - 'The wind might roar, and the waves they might dash, but you will not drown on Lac Sainte Pierre - so long as you stay on the shore.
