Simple extraction example.

{
  "extract": [
    {
      "format": "json",
      "source_reference_key": "ifs_export_reply_payload",
      "extract_rules": [
        {
          "value_path": "MessageId[0].value",
          "target_schema_id": "ifs_reply_message_id"
        }
      ]
    }
  ]
}

More complex configuration example using extraction from two different source_reference_key and two extract_rules in the second one. There is also the condition used, which is reference to a document ID in the annotation which triggers the execution of the extraction.

{
  "extract": [
    {
      "format": "json",
      "extract_rules": [
        {
          "value_path": "doc_id",
          "target_schema_id": "erp_doc_id"
        }
      ],
      "source_reference_key": "api_xml_export_reply_payload"
    },
    {
      "format": "json",
      "condition": "@{api_gate}",
      "extract_rules": [
        {
          "value_path": "status_code",
          "target_schema_id": "erp_api_status_code"
        },
        {
          "value_path": "headers.etag",
          "target_schema_id": "erp_api_etag"
        }
      ],
      "source_reference_key": "api_xml_export_reply_headers"
    }
  ]
}
