    2323First, data is copied from elsewhere to the staging area in preparation for processing.  Processed data is written to the work area.  After the processed data are finalized, they can be moved into a final `cosmo/data/{survey}/{release}/` directory. That area is restricted to the cosmo project user to ensure some level of consistency for the data written there.  This process should be viewed like SDSS data releases: the data are processed and organized elsewhere, and then when finalized (and only then) they are moved into the final data release directories, controlled by the cosmo user.  Once written and released, these data are frozen -- never updated nor removed.
