A resource manifestation is a rendition of a resource at a specific point in time and space. A conceptual mapping exists between a resource and a resource manifestation (or set of manifestations), in the sense that the resource has certain properties – e.g., its URI, its intended purpose, etc. – which are inherited by each manifestation, although the specific structure, form, and content of the manifestation may vary according to factors such as the environment in which it is displayed, the time it is accessed, etc. Regardless of the form the manifestation’s rendering ultimately takes, the conceptual mapping to the resource is preserved.
