    103103Before releasing PDAF V3.0 with its now PDAF3-interface routines for the analysis step, using the PDAF Observation Module Interface (PDAF-OMI) was recommended. PDAFlocal was introduced with PDAF V2.3 in September 2024 as an add-on to PDAF-OMI for local filters. With PDAFlocal we simplified the localization of the state vector. Implementations done before the release of PDAF V2.3 likely use PDAF-OMI without PDAFlocal. This mean they call user-procided routines `g2l_state_pdaf` and `l2g_state_pdaf`.

    109109The full interface omits the use of PDAF-OMI for the observation handling, and PDAFlocal for the simplified handling of localization. Using the full interface is an 'expert mode' because it requires to implement a larger number of call-back routines. Nonetheless, assimilation systems implemented before the introduction of PDAF-OMI with Version 1.16 in November 2020 might still use this approach.
