MeTaMaF: Metadata Tagging and Mapping Framework for Managing Multimedia Content

Metadata comes into forefront as a savior of multimedia search and management. However, the existence of the diverse set of metadata standards and the different vocabularies used by these standards has made that task especially challenging in recent days. In this paper, we propose a framework for managing multimedia content by effectively dealing with the heterogeneous multimedia metadata in a transparent fashion. The cornerstone of our approach is to leverage the existing metadata standards and provide schema and data level mapping among them. The proposed framework also allows adding new tags/vocabularies with the given metadata vocabularies, defining equivalency relationship among those vocabularies, and separately managing the metadata vocabularies outside of the actual media files. We have developed a prototype of the framework and evaluated its performance in terms of some basic query execution times
