Abstract: The design for the James Webb Space Telescope (JWST) Data Management System (DMS) Associations processing has been completed and is presented here. Associations capture the relationship between exposures and higher level data products. Associations as intended by a proposal can be contained within a single observation or extend over multiple observations within a proposal. These candidate associations are provided by the Proposal Planning System (PPS) to DMS where they are converted into Association Pools and Association Generator Tables that serve as inputs to the automated processing which creates the combined data products. Association Pools are generated to capture a list of exposures that could potentially form associations and provide relevant information about those exposures. The Association Generator creates one or more association definitions in Association Table format from a single input Association Pool. Based on each Association Table defining a set of exposures to be combined and the type of combination to be performed, the calibration software creates Associated Data Products, such as mosaics. This scheme is conducive to eventually produce Associations for observations from multiple proposals as is done with the Hubble Legacy Archive (HLA).
