The WPSSO Core plugin provides support for hundreds of Schema types, and can read data from dozens of supported third-party plugins and service APIs. The most popular Schema properties can be customized easily in the Document SSO metabox, and if required, the [schema] shortcode can be used to define additional properties and types for sections of the content.
Please note that the [schema] shortcode is meant for advanced users only and is not required for WPSSO Core to create complete and accurate Schema JSON-LD markup for the content. You should avoid using the [schema] shortcode unless you're very familiar with https://schema.org markup and have very specific, non-standard requirements. If you use the [schema] shortcode, make sure you always validate any change with the Schema Markup Validator and the Google Rich Results Test tool.
