Deprecate an XDM field

In Experience Data Model (XDM), you can deprecate a field within a schema or custom resource by using the Schema Registry API. Deprecating a field causes it to be hidden from downstream UIs such as the Profiles workspace and Customer Journey Analytics, but it is otherwise a non-breaking change and does not negatively affect existing data flows.

This document covers how to deprecate fields for different XDM resources.

Getting started

This tutorial requires making calls to the Schema Registry API. Please review the developer guide for important information that you need to know in order to make these API calls. This includes your {TENANT_ID}, the concept of “containers”, and the required headers for making requests (with special attention to the Accept header and its possible values).

Deprecate a custom field

To deprecate a field in a custom class, field group, or data type, update the custom resource through a PUT or PATCH request and add the attribute meta:status: deprecated to the field in question.

NOTE

For general information on updating custom resources in XDM, refer to the following documentation:

The example API call below deprecates a field in a custom data type.

API format

PATCH /tenant/datatypes/{DATA_TYPE_ID}

Request

The following request deprecates the expansionArea field for a data type that describes a real-estate property.

curl -X PATCH \
  https://platform.adobe.io/data/foundation/schemaregistry/tenant/datatypes/_{TENANT_ID}.datatypes.8779fd45d6e4eb074300023a439862bbba359b60d451627a \
  -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' \
  -d '[
        {
          "op": "add",
          "path": "/properties/expansionArea/meta:status",
          "value": "deprecated"
        }
      ]'

Response

A successful response returns the update details of the custom resource, with the deprecated field containing a meta:status value of deprecated. The example response below has been truncated for space.

Deprecate a standard field in a schema

Fields from standard classes, field groups, and data types cannot be deprecated directly. Instead, you can deprecate their use in the individual schemas that employ these standard resources by using a descriptor.

Create a field deprecation descriptor

To create a descriptor for the schema fields you want to deprecate, make a POST request to the /tenant/descriptors endpoint.

API format

POST /tenant/descriptors

Request

curl -X POST \
  https://platform.adobe.io/data/foundation/schemaregistry/tenant/descriptors \
  -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' \
  -d '{
        "@type": "xdm:descriptorDeprecated",
        "xdm:sourceSchema": "https://ns.adobe.com/{TENANT_ID}/schemas/c65ddf08cf2d4a2fe94bd06113bf4bc4c855e12a936410d5",
        "xdm:sourceVersion": 1,
        "xdm:sourceProperty": "/faxPhone"
      }'
Property Description
@type The type of descriptor. For a field deprecation descriptor, this value must be set to xdm:descriptorDeprecated.
xdm:sourceSchema The URI $id of the schema you are applying the descriptor to.
xdm:sourceVersion The version of the schema you are applying the descriptor to. Should be set to 1.
xdm:sourceProperty The path to the property within the schema that you are applying the descriptor to. If you want to apply the descriptor to multiple properties, you can provide a list of paths in the form of an array (for example, ["/firstName", "/lastName"]).

Response

{
    "@id": "d882b1202bac0ac71f1e31fbcd9afbcc37f364270186b4b3",
    "@type": "xdm:descriptorDeprecated",
    "xdm:sourceSchema": "https://ns.adobe.com/{TENANT_ID}/schemas/c65ddf08cf2d4a2fe94bd06113bf4bc4c855e12a936410d5",
    "xdm:sourceVersion": 1,
    "xdm:sourceProperty": "/faxPhone",
    "imsOrg": "{IMS_ORG}",
    "version": "1",
    "meta:containerId": "tenant",
    "meta:sandboxId": "28e74200-e3de-11e9-8f5d-7f27416c5f0d",
    "meta:sandboxType": "production"
}

Verify the deprecated field

After the descriptor has been applied, you can verify whether the field has been deprecated by looking up the schema in question while using the appropriate Accept header.

NOTE

Showing deprecated fields when listing schemas is currently not supported.

API format

GET /tenant/schemas

Request

To include information on deprecated fields in the API response, you must set the Accept header to application/vnd.adobe.xed-deprecatefield+json; version=1.

curl -X GET \
  https://platform.adobe.io/data/foundation/schemaregistry/tenant/schemas/_{TENANT_ID}.schemas.c65ddf08cf2d4a2fe94bd06113bf4bc4c855e12a936410d5 \
  -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 'Accept: application/vnd.adobe.xed-deprecatefield+json; version=1'

Response

A successful response returns the details of the schema, with the deprecated field containing a meta:status value of deprecated. The example response below has been truncated for space.

"faxPhone": {
    "title": "Fax phone",
    "description": "Fax phone number.",
    "type": "object",
    "meta:xdmType": "object",
    "properties": {},
    "meta:referencedFrom": "https://ns.adobe.com/xdm/context/phonenumber",
    "meta:xdmField": "xdm:faxPhone",
    "meta:status": "deprecated"
}
