The EFD is a powerful tool for correlating pipelines behavior with the state of the observatory. Since it contains the logging information published to the service abstraction layer (SAL) for all sensors and devices on the summit, it is a one stop shop for looking up the state of the observatory at a given moment. The expectation is that the science pipelines validation, science verification, and commissioning teams will all need, at one time or another, to get information like this for measuring the sensitivity of various parts of the system on observatory state: e.g. temperature, dome orientation, wind speed and direction, gravity vector. This leads to the further expectation that the various DM and commissioning teams will want to work with a version of the EFD that is accessed like a traditional relational database, possibly with linkages between individual exposures and specific pieces of observatory state. This implies the need for another version of the EFD (called the DM-EFD here) that has had transforms applied to the raw EFD that make it more immediately applicable to questions the DM team will want to ask.
