 The value _MUST_ be a string, and the value _MUST_ be an HTTP(S) URI for resources defined in this specification. If the resource is retrievable via HTTP(S), then the URI _MUST_ be the URI at which it is published. External resources, such as profiles, _MAY_ have non-HTTP(S) URIs defined by other communities.
 
-The existence of an HTTP(S) URI in the `id` property does not mean that the URI will always be dereferencable.  If the resource with the `id` property is [embedded][prezi30-terminology], it _MAY_ also be dereferenceable. If the resource is referenced (again, see the [terminology section][prezi30-terminology] for an explanation of "referenced"), it _MUST_ be dereferenceable. The [definitions of the Resources][prezi30-resource-structure] give further guidance.
