      Ok, let me propose the following.&nbsp; Next offline meeting I will
      present the state of the conversion to the distilled SEST format
      (Simulated Event STorage format).&nbsp; At that point we can decide
      whether it is completed and tested sufficiently well to go into
      production or not, or whether to proceed with the simulation hddm
      data model in its present state.<br>
      <br>
      SEST will be what I call the simulated event storage format.&nbsp; SEST
      becomes REST as soon as it has passed through dana and the hits
      information and simulation-truth elements are suppressed.&nbsp; It will
      contain the simulated hitView structure (properly factorized into
      pure hits and pure truth tags) plus a hook for appending the REST
      structure (for people who want both hits and reconstructed results
      for studies) plus a small handful of other extended truth tags
      that have been introduced by David and Simon over the years, such
      as mcTrajectory, etc.&nbsp; A tool will be provided to strip arbitrary
      SEST files down to bare hits.&nbsp; Such "bare hits" files will also be
      valid SEST files, but missing the information contained in the
      extra structures.&nbsp; The danahddm plugin will be able to read any
      SEST file and properly handle situations where various types of
      information are available or not, according to David's factory
      schema.<br>

      <div>cannot be implemented and tested on a very short time scale.

              I saw this proposal in the minutes Mark circulated.&nbsp; I am
              satisfied with it, and it means that production can
              proceed before I get all of these changes checked in and
              validated.&nbsp; I am still hoping to get the changes in before
              I begin the grid production, since I am saving
              considerable volumes of the intermediate simulation
