Study on DIDL parser and DIA Session Mobility Implementation
MPEG-21 DID 구성 툴과 DIA 세션 모빌리티 툴 개발에 대한 연구
Abstract
This paper describes design and implementation of the DIDL(Digital Item Declaration Language) parser and Session mobility in Digital Item Adaptation. The DIDL is a declaration language which is a uniform and flexible abstraction and interoperable schema for declaring Digital Items. Session mobility specifies a mechanism to preserve a user's current state of interaction with a Digital Item. In this paper, Session mobility is implemented through the DIDL. For session mobility, the XDI (context digital item) shall capture the configuration-state of a Content digital item, shich is defined by the state of Selection elements in DIDL.
