Abstract
AbstractThis paper describes a context sensitive service architecture for digital object dissemination based on OpenURL and MPEG‐21 Digital Item Adaptation (DIA). This architecture entails representing service requests using the OpenURL ContextObjects and conveying the ContextObject Representations with the OpenURL Transport. The rich expressiveness of the Usage Environment Description (UED) tool defined in the MPEG‐21 DIA standard can then be incorporated into the OpenURL ContextObject by means of OpenURL extensibility mechanism, and the MPEG‐21 DIA adaptation engine can be used to construct highly customizable and adaptive context sensitive dissemination services for institutional repositories.
