The application of open hypermedia to temporal media has previously been explored with respect to the link service, in particular link delivery and generic linking. This paper is based on the notion of continuous metadata, in which we use metadata in a temporally significant manner to capture and convey the information required to support linking. With a focus on link creation and live processing, our approach enriches hypermedia content with additional metadata at a number of points between capture and delivery. We illustrate this approach with a tool which assists metadata capture by annotation of continuous media according to a simple ontology.
