Content Pack Structure

Generally speaking, two content pack (.cp) folders are needed under the <VDW_HOME>/Content directory for a single task:

• CUSTOMIZATION_PPM.cp: Contains JSON files that define source entities, extraction entities, and stream entities.
• CUSTOMIZATION_TARGET.cp: Contains JSON files that define target entities.

The folder structure of the content packs is shown as follows:

• CUSTOMIZATION_PPM.cp (root folder)

  • dwmetadata (folder)

    • entities (folder)

      • Source entity JSON (file)

    • streams (folder)

      • Stream entity JSON (file)

  • extmetadata (folder)

    • Extractor entity JSON (file)
  • cp.json (file)

• CUSTOMIZATION_TARGET.cp (root folder)

  • dwmetadata (folder)

    • entities (folder)

      • Target entity JSON (file)
  • cp.json (file)

The following table describes the JSON files.
