Sam,

These types of problems I tried to address some time ago.

But I was not concerned about the duplicity at different times, but that data stored as a one time measurement will be found.

But those in time series will not be found unless explicitly searched for.

There are a number of questions that come up from archetype based queries and how we should handle them. The first is about repeating elements in an observation. The event class of observation is repeating and as such will lead, at times, to duplicate data at different times. For this reason an observation class may return multiple instances of the same data. There are a number of different 'rules' that are starting to become clear.
