The field of application of HyTime is "integrated open hypermedia" (IOH), the "bibliographic model" of hyperlinking wherein an author can, by a suitable reference, link to anything, anywhere, at any time.
Because of HyTime's modular design and flexible conformance rules, implementations need support only those facilities that are within their present capabilities. User investment in hyperdocument preparation is nevertheless encouraged because of the well-defined upward-compatible path to a full hypermedia solution.
HyTime is intended for use as the infrastructure of platform-independent information interchange for hypermedia and synchronized and non-synchronized multimedia applications. Application developers will use HyTime constructs to design their information structures and objects, and the HyTime language to represent them for interchange.
NOTE 9 The HyTime language is not intended for encoding the internal representation of information on which application programs act while executing.
Applications can use HyTime to represent hyperdocuments containing information that is at any stage of rendition, from "revisable" to "optimized for interactive access". An application can also choose to convert a rendition of a HyTime hyperdocument into an optimized form for transmission or interactive presentation.
NOTE 10 Whether the HyTime representation of a hyperdocument can be used in a local file system for direct access by programs will depend on the type of information in the hyperdocument, the speed of the platform, and the functions performed by the applications that access the hyperdocument.
