从Dataframe到XDM架构

数据流（如Parquet文件）的层次结构必须与要上传到的XDM架构的层次结构匹配。

示例数据流

以下示例数据流的结构已映射到实现 XDM Individual Profile 类，并包含与该类型架构关联的最常见字段。

[
    StructField("person", StructType(
        [
            StructField("name", StructType(
                [
                    StructField("courtesyTitle", StringType()),
                    StructField("firstName", StringType()),
                    StructField("lastName", StringType())
                ]
            )),
            StructField("gender", StringType()),
            StructField("birthDayAndMonth", StringType()),
            StructField("birthDate", StringType()),
            StructField("birthYear", LongType())
        ]
    )),
    StructField("identityMap", MapType(
        StructField("CRMID", ArrayType(
            StructType(
                [
                    StructField("id", StringType()),
                    StructField("primary", BooleanType())
                ]
            )
        )),
        StructField("ECID", ArrayType(
            StructType(
                [
                    StructField("id", StringType()),
                    StructField("primary", BooleanType())
                ]
            )
        )),
        StructField("LOYALTYID", ArrayType(
            StructType(
                [
                    StructField("id", StringType()),
                    StructField("primary", BooleanType())
                ]
            )
        ))
    )),
    StructField("homePhone", StructType(
        [
            StructField("number", StringType())
        ]
    )),
    StructField("personalEmail", StructType(
        [
            StructField("address", StringType())
        ]
    )),
    StructField("homeAddress", StructType(
        [
            StructField("street1", StringType()),
            StructField("city", StringType()),
            StructField("stateProvince", StringType()),
            StructField("country", StringType()),
            StructField("postalCode", StringType()),
            StructField("_schema", StructType(
                [
                    StructField("latitude", DoubleType()),
                    StructField("latitude", DoubleType()),
                ]
            ))
        ]
    ))
]

在构建用于Adobe Experience Platform的数据流时，确保其层次结构与现有XDM架构的层次结构完全匹配对于字段正确映射非常重要。

标识到标识映射

标识数组

[
  {
    "xdm:id": "someone1@example.com",
    "xdm:namespace": {
      "xdm:code": "Email"
    }
  },
  {
    "xdm:id": "2eeb6532-82e1-0d58-8955-bf97de66a6f5",
    "xdm:namespace": {
      "xdm:code": "CRMID"
    }
  },
  {
    "xdm:id": "2e3319208000765b-3811c00000000001",
    "xdm:namespace": {
      "xdm:code": "LOYALTYID"
    }
  }
]

映射

下表概述了标识数组的映射要求：

标识字段

identityMap字段

数据类型

身份[0].id

identitymap[电子邮件][{“id”}]

复制为字符串

身份[1].id

identitymap[CRMID][{“id”}]

复制为字符串

身份[2].id

identitymap[LOYALTYID][{“id”}]

复制为字符串

输出XDM

下面是转换为XDM的身份数组：

"identityMap": {
      "Email": [{
         "id": "someone1@example.com"
      }],
      "CRMID": [{
         "id": "2eeb6532-82e1-0d58-8955-bf97de66a6f5"
      }],
      "LOYALTYID": [{
         "id": "2e3319208000765b-3811c00000000001"
      }]
   }
