管理切面并丰富元数据

借助 Knowledge Catalog（以前称为 Dataplex Universal Catalog）中的切面和切面类型，您可以向条目和条目链接添加结构化元数据，以描述数据资产及其关系。此上下文可提高数据可发现性，并帮助您对敏感信息（例如个人身份信息 [PII]）进行分类，以应用数据质量或访问权限政策。

如需详细了解元数据概念，请参阅 Knowledge Catalog 中的元数据简介。如果您是首次使用 Knowledge Catalog 元数据，请参阅向 BigQuery 表添加元数据或创建和使用业务术语库快速入门。

什么是切面类型？

切面类型是可重复使用的资源，提供用于定义切面的相关元数据字段的 JSON 模板。例如，对于合规性信息，您可以定义一个切面类型，其中包含 PII 分类和 GDPR 合规性字段。创建自定义切面类型时，您必须指定符合 Knowledge Catalog 资源命名准则的 ID。

切面类型的类别

切面类型分为自定义切面类型和系统切面类型：

自定义切面类型

您在 Knowledge Catalog 中创建的切面类型称为自定义切面类型。

自定义切面类型可以是全球性的，也可以是区域级的：

全球切面类型：可用于为任何区域中的条目创建切面。如果您需要将相同的结构应用于多个区域中的条目，请选择 global 切面类型，因为您只需定义一次。由于全球切面类型的定义会复制到所有区域，因此如果切面类型架构本身包含敏感信息，或者需要对所有元数据组件实施严格的数据驻留，则此选项可能不适合。
区域切面类型：只能用于为与切面类型位于同一区域的条目创建切面。例如，在 us-central1 中创建的切面类型只能与 us-central1 中的条目搭配使用。如果某种切面类型仅与特定区域中的条目相关，或者为了确保切面类型定义位于所选区域内（这有助于满足数据主权和合规性要求），请选择区域位置。如果您使用区域切面类型，但需要在多个区域中使用相同的结构，则必须在每个区域中创建和管理单独的切面类型定义。

您可以在特定区域位置（例如 us-central1）创建自定义切面类型，也可以将其创建为 global 资源。切面类型的位置会影响其适用范围，并决定可与其搭配使用的条目。

如需了解详情，请参阅项目和位置限制条件。

系统切面类型

Knowledge Catalog 提供、使用和管理的切面类型称为系统切面类型。系统切面类型始终是全球性的，因此可以在任何区域中使用。系统切面类型存储在项目编号为 655216118709 的 Google 管理的项目中。例如 projects/655216118709/locations/global/aspectTypes/schema。

每个系统定义的切面类型、条目类型和条目链接类型都有自己的 IAM 权限。如需了解详情，请参阅系统切面类型、条目类型和条目链接类型的 IAM 权限。

系统切面类型进一步分为可重复使用和受限两类。下表介绍了系统切面类型的类别，以及 Knowledge Catalog 为每个类别提供的切面类型列表：

系统切面类型的类别	说明	Knowledge Catalog 提供的切面类型
可重复使用的系统切面类型	您可以使用这些切面类型来创建或修改切面。	`contacts` `data-profile` `data-quality-scorecard` `generic` `graph-profile` `guidelines` `overview` `schema-join` `schema` `storage` `usage`
受限的系统切面类型	Knowledge Catalog 会管理这些切面类型。您可以读取这些切面类型下的切面，但无法在这些切面类型下创建或修改切面。	包括但不限于： `analytics-hub` `aspecttype-aspect` `bigquery-dataset` `bigquery-table` `cloudsql-database` `cloudsql-instance` `cloudsql-table` `entrygroup-aspect` `entrytype-aspect` `sensitive-data-protection-profile` `storage-bucket` `storage-folder`

自定义切面类型和 Gemini in BigQuery

Gemini 上下文检索边界：Gemini in BigQuery 会根据标准架构定义、表限制条件以及表或列说明字段来生成 SQL 和进行数据推理。Knowledge Catalog 中用户定义的自定义切面类型存储在目录平面中，用于治理、搜索和 API 检索，但不会动态注入到 Gemini 的上下文提示检索流水线中。

建议的最佳实践

为确保 Gemini in BigQuery 能够看到业务逻辑、语义上下文或开发者备注，请直接在表和列说明字段中、标准 overview 方面中或使用业务术语库术语记录这些信息。

如需了解详情，请参阅将 Knowledge Catalog 与 BigQuery 搭配使用。

什么是切面？

利用切面，您可以捕获条目或条目链接中的元数据，以提供有意义的上下文。您可以使用切面来存储以下类型的元数据：

业务元数据：提供业务上下文，例如数据分类。例如，受监管的行业需要保护分布式数据系统中的 PII，例如姓名、地址和由政府签发的身份证件号码。对分布式数据资产进行编目后，您可以将数据分类为 PII，然后对数据应用数据质量或访问政策。
技术元数据：条目或条目链接的技术详细信息，包括：
- 对于条目：数据资产本身的详细信息，例如其架构。
- 对于条目链接：数据资产之间关系的详细信息，例如联接详细信息。
数据派生的元数据：根据数据本身生成的信息，例如 BigQuery 表中的统计信息。

切面是父级条目资源的组成部分，而不是单独的独立资源。修改切面会更新包含该切面的条目。如需跟踪这些修改，您可以订阅元数据更改 Feed。

方面放置和目标级别

每个切面都是切面类型模板的一个实例，该模板定义了您必须填充的字段，例如 {"pii_classification": "confidential", "gdpr_compliant": true}。您可以将切面应用于整个表、单个表列或条目链接。您可以应用切面的位置以及切面可以出现的次数取决于目标资源类型：

目标资源	支持的级别	基数上限
条目数	条目级或列级	在条目级别，每个切面类型最多只能有一个切面。允许在不同列中为每个切面类型设置多个切面。
条目链接	仅限关联级别	每个链接的每个切面类型最多只能有一个切面。

切面类别

切面分为必需切面和可选切面：

必需切面

必需的切面是指在创建条目或条目链接时必须使用的切面。此类切面由条目类型或条目链接类型定义。属于特定类型的所有资源必须始终具有该类型定义的所有必需切面。

Knowledge Catalog 会管理系统条目所需的切面（例如架构）。

请注意以下几点：

您只能将必需的切面与条目相关联，而不能与条目列相关联。
您无法从条目或条目链接中删除必需的切面。
您可以读取系统条目的必需切面，但无法修改它们。
数据切面不能是必需切面。

可选切面

您可以将可选切面与条目或条目列相关联。您可以在创建条目时填充可选切面，也可以稍后通过更新条目来填充。

请注意以下几点：

填充可选切面后，您可以将其删除。
条目链接仅支持必需切面。

数据切面

某些切面包含从条目的底层数据派生的信息，而不是有关条目的元数据。这些切面称为数据切面。例如，数据分析扫描或数据质量扫描的结果包含从数据本身派生的统计信息，因此被归类为数据方面。

属于数据切面的系统切面类型包括：

data-profile：包含数据分析扫描的结果。如需了解详情，请参阅数据分析简介。
data-quality-scorecard：包含数据质量得分的摘要。
data-rules：将数据质量规则附加到条目。
data-quality-rule-template：定义可重复使用的数据质量规则模板。

准备工作

在创建和管理方面类型及切面之前，请完成本部分中所述的任务。

所需的角色

如需获得创建和管理切面类型及切面所需的权限，请让您的管理员为您授予资源的以下 IAM 角色：

拥有 Knowledge Catalog 中的元数据资源（包括切面类型和数据切面）的整套权限：Dataplex Catalog Admin (roles/dataplex.catalogAdmin)
在 Knowledge Catalog 中创建和管理元数据资源，包括切面类型和数据切面：Dataplex Catalog Editor (roles/dataplex.catalogEditor)
拥有自定义切面类型的整套权限（除了使用切面类型创建或修改条目的权限）：Dataplex Aspect Type Owner (roles/dataplex.aspectTypeOwner)
查看切面类型以及与其关联的 IAM 政策：Dataplex Catalog Viewer (roles/dataplex.catalogViewer)
使用切面类型创建和修改具有相应切面的条目：Dataplex Aspect Type User (roles/dataplex.aspectTypeUser)
添加一些系统切面类型的切面，例如 schema、schema-join、overview、contacts：Dataplex Entry and EntryLink Owner (roles/dataplex.entryOwner)

如需详细了解如何授予角色，请参阅管理对项目、文件夹和组织的访问权限。

您也可以通过自定义角色或其他预定义角色来获取所需的权限。

如需了解详情，请参阅 Knowledge Catalog IAM 角色。

REST

如需创建自定义切面类型，请使用 aspectType.create 方法。

创建自定义切面类型后，您可以向条目添加切面。

使用“记录 ID”和“记录引用”字段的示例

您可以使用记录 ID 和记录引用字段进行递归引用。以下示例展示了如何使用这些字段：

假设一个名为 Employee 的切面类型，其中包含以下字段：

名称（类型：Text）
开始日期（类型：Date & time）
标识（类型：Text）
当前地址（类型：Record）
永久地址（类型：Record）

两个地址字段（当前地址和永久地址）的数据类型均为 Record。为避免重复，您可以在定义这些字段时设置记录 ID 和记录引用 值。

定义当前地址字段时，您可以将记录 ID 指定为 address-field。对于永久地址，您可以为记录引用指定相同的值 (address-field)。例如：

名称（类型：Text）
开始日期（类型：Date & time）
标识（类型：Text）
当前地址（类型：Record，记录 ID：address-field）
永久地址（类型：Record，记录引用：address-field）

这样一来，您便无需重复其他地址的字段。

向条目添加切面

创建自定义切面类型后，您可以创建该类型的切面。如需向条目添加切面，您必须更新该条目，因为切面存储在条目中。

请注意以下几点：

您可以向条目或条目列添加切面。
您只能修改自定义条目的必需切面。您无法删除必需的切面。
您可以修改和删除自定义条目及系统条目的可选切面。

end

如需向条目对象添加切面，请参阅 #required_aspects=。

REST

如需向条目或条目列添加切面，请使用 entry.patch 方法。

不支持在条目中创建和使用切面，因为相应的切面类型和条目位于不同的 Google Cloud 组织中。

附加可重复使用的系统切面类型的切面

您可以将可重复使用的系统切面类型的切面附加到条目。

您可以在 Google Cloud 控制台中修改可重复使用的切面类型的切面，具体取决于其结构。 Google Cloud 控制台不支持修改包含嵌套字段的切面类型。您必须使用 gcloud 命令行工具或 REST API 来附加或更新此类型的切面。

数据质量计分卡

数据质量计分卡是一个方面，用于提供数据质量摘要，通常基于数据质量扫描或其他流程。您可以将数据质量统计信息摘要图表附加到条目，以提供自定义数据质量信息。为此，请附加系统定义的类型 data-quality-scorecard 的切面。

data-quality-scorecard 方面中的 data 字段可以包含以下字段：

job：可选。一条记录，其中包含有关生成计分卡的作业的详细信息。
- name：数据质量作业的资源名称。
- runTime：数据质量作业的运行时间。
score：可选。总体数据质量得分。分数范围为 [0, 100]。
status：必填。数据质量统计信息摘要的状态，指明其是否通过了质量阈值（PASS 或 FAIL）。
dimensions：可选。维度结果数组。每个结果都包含：
- name：维度的名称。可以是 ACCURACY、COMPLETENESS、CONSISTENCY、FRESHNESS、UNIQUENESS、VALIDITY 或 VOLUME，也可以是自定义维度名称。自定义维度名称必须使用大写字母，且长度不得超过 30 个字符。
- score：维度级总体得分，范围为 [0, 100]。
- status：维度的状态，指示其是否通过了质量阈值（PASS 或 FAIL）。
columns：可选。列结果的数组。每个结果都包含：
- name：列的名称。
- score：列级总体得分，范围为 [0, 100]。
- status：列的状态，指示其是否通过了质量阈值（PASS 或 FAIL）。
- dimensions：列的维度得分数组。每个维度得分都包含：
  - name：维度的名称。
  - score：维度的得分，范围为 [0, 100]。
  - status：列维度的状态，指示其是否通过了质量阈值（PASS 或 FAIL）。

运行附加切面的命令时，该命令会替换该特定切面的所有现有数据。例如，如果您使用显示得分为 90 的新文件更新得分为 80 的记分卡，则 80 将被覆盖。它不会合并数据。

如需附加数据质量统计信息，请按以下步骤操作：

gcloud

如需更新条目的切面，请使用 gcloud dataplex entries update-aspects 命令。

创建一个包含以下内容的 JSON 文件 (dq-aspect.json)。

  {
    "dataplex-types.global.data-quality-scorecard": {
      "data": {
        "score": 0.8,
        "status": "PASS",
        "dimensions": [
          {
            "name": "completeness",
            "score": 0.9,
            "status": "PASS"
          },
          {
            "name": "uniqueness",
            "score": 0.7,
            "status": "FAIL"
          }
        ],
        "columns": [
          {
            "name": "col1",
            "score": 0.85,
            "status": "PASS"
          }
        ]
      }
    }
  }
}

运行以下命令：
```
  gcloud dataplex entries update-aspects ENTRY_ID
  --location=LOCATION
  --entry-group=ENTRY_GROUP_ID
  --project=PROJECT_ID
  --aspects=dq-aspect.json
```
执行以下变量替换操作：
- ENTRY_ID：条目的 ID，例如 example-entry
- LOCATION：条目的位置，例如 us-central1
- ENTRY_GROUP_ID：条目组的 ID，例如 example-entry-group
- PROJECT_ID：项目的 ID，例如 example-project

REST

如需更新条目的切面，请使用 entry.patch 方法。

创建一个名为 payload.json 的文件，并将请求中的 JSON 内容粘贴到其中。


  {
    "aspects": {
      "dataplex-types.global.data-quality-scorecard": {
        "data": {
          "score": 80,
          "status": "PASS",
          "dimensions": [
            {
              "name": "completeness",
              "score": 90,
              "status": "PASS"
            },
            {
              "name": "uniqueness",
              "score": 70,
              "status": "FAIL"
            }
          ],
          "columns": [
            {
              "name": "col1",
              "score": 85,
              "status": "PASS"
            }
          ]
        }
      }
    }
  }

在终端中运行以下命令：

 curl -X PATCH \
 -H "Authorization: Bearer $(gcloud auth print-access-token)" \
 -H "Content-Type: application/json" \
 -d @payload.json \
 "https://dataplex.googleapis.com/v1/projects/<var>PROJECT_ID</var>/locations/<var>LOCATION</var>/entryGroups/<var>ENTRY_GROUP_ID</var>/entries/<var>ENTRY_ID</var>?updateMask=aspects"

替换以下内容：

PROJECT_ID：项目的 ID，例如 example-project
LOCATION：条目的位置，例如 us-central1
ENTRY_GROUP_ID：条目组的 ID，例如 example-entry-group
ENTRY_ID：条目的 ID，例如 example-entry
