// This method is deprecated because it has a misleading name. Please use ToRESTFriendlyName
// instead
//
// NOTE: actually the "canonical name" in this method should be named "REST friendly OpenAPI name",
// which is different from "canonical name" defined in GetCanonicalTypeName. The "canonical name" defined
// in GetCanonicalTypeName means Go type names with full package path.
//
// Examples of REST friendly OpenAPI name:
//
// Input: k8s.io/api/core/v1.Pod
// Output: io.k8s.api.core.v1.Pod
//
// Input: k8s.io/api/core/v1
// Output: io.k8s.api.core.v1

// OpenAPICanonicalTypeNamer is an interface for models without Go type to seed model name.

// OpenAPI canonical names are Go type names with full package path, for uniquely indentifying

// should be used. For custom resource definition (CRD), the canonical name is expected to be
//
// group/version.kind

// Examples of canonical name:
//
// Go type: k8s.io/kubernetes/pkg/apis/core.Pod
// CRD: csi.storage.k8s.io/v1alpha1.CSINodeInfo

// Example for vendored Go type:

// Original full path: k8s.io/kubernetes/vendor/k8s.io/api/core/v1.Pod
// Canonical name: k8s.io/api/core/v1.Pod
