Manage data usage labels for datasets using APIs

The Dataset Service API allows you to apply and edit usage labels for datasets. It is part of Adobe Experience Platform’s data catalog capabilities, but is separate from the Catalog Service API which manages dataset metadata.

This document covers how to manage labels for datasets and fields using the Dataset Service API. For steps on how to manage data usage labels themselves using API calls, see the labels endpoint guide for the Policy Service API.

Getting started

Before you read this guide, follow the steps outlined in the getting started section in the Catalog developer guide to gather the required credentials to make calls to Platform APIs.

In order to make calls to the endpoints outlined in this document, you must have the unique id value for a specific dataset. If you do not have this value, see the guide on listing Catalog objects to find the IDs of your existing datasets.

Look up labels for a dataset

You can look up the data usage labels that have been applied to an existing dataset by making a GET request to the Dataset Service API.

API format

GET /datasets/{DATASET_ID}/labels

Request

curl -X GET \
  'https://platform.adobe.io/data/foundation/dataset/datasets/5abd49645591445e1ba04f87/labels' \
  -H 'Authorization: Bearer {ACCESS_TOKEN}' \
  -H 'x-api-key: {API_KEY}' \
  -H 'x-gw-ims-org-id: {IMS_ORG}' \
  -H 'x-sandbox-name: {SANDBOX_NAME}'

Response

A successful response returns the data usage labels that have been applied to the dataset.

{
  "AEP:dataset:5abd49645591445e1ba04f87": {
    "imsOrg": "{IMS_ORG}",
    "labels": [ "C1", "C2", "C3", "I1", "I2" ],
    "optionalLabels": [
      {
        "option": {
          "id": "https://ns.adobe.com/{TENANT_ID}/schemas/c6b1b09bc3f2ad2627c1ecc719826836",
          "contentType": "application/vnd.adobe.xed-full+json;version=1",
          "schemaPath": "/properties/repositoryCreatedBy"
        },
        "labels": [ "S1", "S2" ]
      }
    ]
  }
}

Apply labels to a dataset

You can create a set of labels for a dataset by providing them in the payload of a POST or PUT request to the Dataset Service API. Using either of these methods overwrites any existing labels and replaces them with those provided in the payload.

API format

POST /datasets/{DATASET_ID}/labels
PUT /datasets/{DATASET_ID}/labels

Request

The example PUT request below updates the existing labels for a dataset, as well as a specific field within that dataset. The fields provided in the payload are the same as would be required for a POST request.

When making API calls that update the existing labels of a dataset (PUT), an If-Match header that indicates the current version of the dataset-label entity in Dataset Service must be included. In order to prevent data collisions, the service will only update the dataset entity if the included If-Match string matches the latest version tag generated by the system for that dataset.

To retrieve the most recent version of the dataset-label entity, make a GET request to the /datasets/{DATASET_ID}/labels endpoint. The current value is returned in the response under an etag header. When updating existing dataset labels, best practice is to first perform a lookup request for the dataset in order to fetch its latest etag value before using that value in the If-Match header of your subsequent PUT request.

curl -X PUT \
  'https://platform.adobe.io/data/foundation/dataset/datasets/5abd49645591445e1ba04f87/labels' \
  -H 'Authorization: Bearer {ACCESS_TOKEN}' \
  -H 'x-api-key: {API_KEY}' \
  -H 'x-gw-ims-org-id: {IMS_ORG}' \
  -H 'x-sandbox-name: {SANDBOX_NAME}' \
  -H 'Content-Type: application/json' \
  -H 'If-Match: 8f00d38e-0000-0200-0000-5ef4fc6d0000' \
  -d '{
        "labels": [ "C1", "C2", "C3", "I1", "I2" ],
        "optionalLabels": [
          {
            "option": {
              "id": "https://ns.adobe.com/{TENANT_ID}/schemas/c6b1b09bc3f2ad2627c1ecc719826836",
              "contentType": "application/vnd.adobe.xed-full+json;version=1",
              "schemaPath": "/properties/repositoryCreatedBy"
            },
            "labels": [ "S1", "S2" ]
          }
        ]
      }'

Response

A successful response returns the updated set of labels for the dataset.

{
  "labels": [ "C1", "C2", "C3", "I1", "I2" ],
  "optionalLabels": [
    {
      "option": {
        "id": "https://ns.adobe.com/{TENANT_ID}/schemas/c6b1b09bc3f2ad2627c1ecc719826836",
        "contentType": "application/vnd.adobe.xed-full+json;version=1",
        "schemaPath": "/properties/repositoryCreatedBy"
      },
      "labels": [ "S1", "S2" ]
    }
  ]
}

Next steps

By reading this document, you have learned how to manage data usage labels for datasets and fields using the Dataset Service API.

Once you have added data usage labels at the dataset- and field-level, you can begin to ingest data into Experience Platform. To learn more, start by reading the data ingestion documentation.

You can also now define data usage policies based on the labels you have applied. For more information, see the data usage policies overview.
