We in principle have already all the building blocks to create complete (sequencer) observing scripts. A specific objective over the coming year is the completion and implementation of a fully integrated Observing Block system that will provide a system that allows to completely define observations. Beyond that this can be converted to scripts that execute the observations, the information can be used to check for validity of the observations, and used to define instrument set-ups and plan observations (as already to a certain extend is provided for the fast-track service program). By providing a full description of an observation, this system will also allow for all the corresponding keywords to be set to proper values in each exposure. This can then serve as input to any (automatic) post-processing of the data (quality control, archiving, [pipeline-]reduction, etc).
