You can now extend the standard customer profile schema with custom attributes and data structures that reflect your business needs. Profile extensions support both simple values and more complex structures such as arrays of objects, and can be used when building audiences and personalizing experiences.
What's included
Custom schema extensions - add profile attributes beyond the standard profile schema.
Flexible data structures - model customer data using simple and complex values.
Audience support - after the schema is published, use profile extensions as audience criteria when personalizing your website or targeting content.
