Abstract:
Content creation and presentation are key activities in a multimedia digital library (MDL). The proper design and intelligent implementation of these services provide a stable base for overall MDL functionality. This paper presents the framework and the implementation of these
services in the latest version of the “Virtual Encyclopaedia of Bulgarian
Iconography” multimedia digital library. For the semantic description of the
iconographical objects a tree-based annotation template is implemented. It
provides options for autocompletion, reuse of values, bilingual entering of
data, automated media watermarking, resizing and conversing. The paper
describes in detail the algorithm for automated appearance of dependent values for different characteristics of an iconographical object. An algorithm for avoiding duplicate image objects is also included. The service for automated
appearance of new objects in a collection after their entering is included as
an important part of the content presentation. The paper also presents the
overall service-based architecture of the library, covering its main service
panels, repositories and their relationships. The presented vision is based
on a long-term observation of the users’ preferences, cognitive goals, and
needs, aiming to find an optimal functionality solution for the end users.
