Compose a schema with a standard class

A schema can be thought of as the blueprint for the data you wish to ingest into Experience Platform. Each schema is composed of a class and zero or more schema field groups. In other words, you do not have to add a field group in order to define a schema, but in most cases at least one field group is used.

Assign a class

The schema composition process begins with the selection of a class. The class defines key behavioral aspects of the data (record vs time series), as well as the minimum fields that are required to describe the data that will be ingested.

The schema you are making in this tutorial uses the XDM Individual Profile class. XDM Individual Profile is an standard class provided by Adobe for defining record behavior. More information on behavior can be found in basics of schema composition.

To assign a class, an API call is made to create (POST) a new schema in the tenant container. This call includes the class the schema will implement. Each schema may only implement one class.

API format

POST /tenant/schemas

Request

The request must include an allOf attribute which references the $id of a class. This attribute defines the “base class” that the schema will implement. In this example, the base class is the XDM Individual Profile class. The $id of the XDM Individual Profile class is used as the value of the $ref field in the allOf array below.

Response

A successful request returns HTTP Response Status 201 (Created) with a response body that contains the details of the newly created schema, including the $id, meta:altIt, and version. These values are read-only and are assigned by the Schema Registry.
