Examples of com.linkedin.data.schema.TyperefDataSchema

com.linkedin.data.schema.TyperefDataSchema
{@link DataSchema} for typeref.A {@link TyperefDataSchema} is used to provide an alternate nameand additional metadata on another type. This is especially useful for creating types to differentiate different uses of the same primitive types. For example, string may be used to store an Uniform Resource Name or a locale. It is desirable to use a "urn" or "locale" instead of "string" for these uses.
