More and more content in current inter and intranets is available as hyperdata, a form easing its distribution and semantic organization. In the framework of the Internet's Web-portals and pay-sites, mechanisms for login based on username and password enable the dynamic customization as

For applications that store very large volumes of multimedia data, hierarchical storage offers a scalable and economical alternative to store data on magnetic disks. In a hierarchical storage architecture data is stored on a tape or optical disk based tertiary storage layer with the secondary storage disks serving as a cache or buffer. Due to the need for swapping media on drives, retrieving multimedia data from tertiary storage can potentially result in large delays before playback (startup latency) begins as well as during playback (jitter). In this paper we address the important problem of reducing startup latency and jitter for very large multimedia repositories. We propose that secondary storage should not be used as a cache in the traditional manner — instead, most of the secondary storage should be used to permanently store partial objects. Furthermore,...

This also allows the schemes to be employed when no prior information about the access pattern is available. Interestingly, our results show that the probabilities of object access do not ...
