View a schema definition

You can view the schema for any data store containing data that supports a schema, such as structured data, website data with structured data, or unstructured data with structured data.

You can view the schema in the Google Cloud console or by using the dataStores.schemas.get API method. Viewing the schema for a website is supported only over the REST API.

Console

To view a schema in the Google Cloud console, follow these steps.

  1. If you are viewing an auto-generated schema, make sure that you have completed data ingestion. Otherwise, the schema might not be available yet.

  2. In the Google Cloud console, go to the AI Applications page.

    AI Applications

  3. In the navigation menu, click Data Stores.

  4. In the Name column, click the data store with the schema that you want to view.

  5. Click the Schema tab to view the schema for your data.

REST

To use the API to get the definition for your schema, follow these steps:

  1. If you are viewing an auto-generated schema, make sure that you have completed data ingestion. Otherwise, the schema might not be available yet.

    To view the schema for data stores with websites or unstructured data with metadata, skip to Step 3 to call the schema.get method.

  2. Find your data store ID. If you already have your data store ID, skip to the next step.

    1. In the Google Cloud console, go to the AI Applications page and in the navigation menu, click Data Stores.

      Go to the Data Stores page

    2. Click the name of your data store.

    3. On the Data page for your data store, get the data store ID.

  3. Use the schemas.get API method to get your schema definition.

    curl -X GET \
-H "Authorization: Bearer $(gcloud auth print-access-token)" \
-H "Content-Type: application/json" \
"https://discoveryengine.googleapis.com/v1/projects/PROJECT_ID/locations/global/collections/default_collection/dataStores/DATA_STORE_ID/schemas/default_schema"

    Replace the following:

    • PROJECT_ID: the ID of your project.
    • DATA_STORE_ID: the ID of your data store.
