5. Update MARC_BIB (Overlay)

Jan 20, 2022

Description

Update MARC + update Instance, MARC-to-MARC match

NB: Update Instance action is implicit

Flow

  1. JobDefinition (uuid, profile - defines job type: insert/update) for import created in mod-srm

  2. MARC file + JobDefinition ID are uploaded from WEB client to mod-data-import (stored in memory, can be persisted. possible oom)

  3. MARC records are packed into batches and put to Kafka queue DI_RAW_RECORDS_CHUNK_READ

  4. mod-srm reads batches from the queue, validates them and publishes DI_MARC_FOR_UPDATE_RECEIVED event - since JobProfile contains an action for MARC_Bib update, original records are not saved in mod-srs. 

  5. mod-srs reads message from DI_MARC_FOR_UPDATE_RECEIVED. Tries to find entity according to match criteria

  6. If found: exports result to DI_SRS_MARC_BIB_RECORD_MATCHED

    1. mod-srs receives match result and updates the MARC_Bib record according to profile. And publishes result to DI_SRS_MARC_BIB_RECORD_MODIFIED_READY_FOR_POST_PROCESSING

    2. mod-inventory reads message from DI_SRS_MARC_BIB_RECORD_MODIFIED_READY_FOR_POST_PROCESSING, updates the corresponding Instance and if no more actions in profile: export to DI_COMPLETE

  7. If not found:  DI_SRS_MARC_BIB_RECORD_NOT_MATCHED event is published
