Profiles are essentially shorthand for a schema URL. The core profiles for DataShaper are defined here, but any application can define one as a string. Signature: ```typescript export type Profile = KnownProfile /** * Any other custom profile string can be specified by applications. */ | string; ``` References: [KnownProfile](./schema.knownprofile.md)
