Milos: a multimedia content management system for digital library applications

This paper describes the MILOS Multimedia Content Management System: a general purpose software component tailored to support design and effective implementation of digital library applications. MILOS supports the storage and content based retrieval of any multimedia documents whose descriptions are provided by using arbitrary metadata models represented in XML. MILOS is flexible in the management of documents containing different types of data and content descriptions; it is efficient and scalable in the storage and content based retrieval of these documents. The paper illustrates the solutions adopted to support the management of different metadata descriptions of multimedia documents in the same repository, and it illustrates the experiments performed by using the MILOS system to archive documents belonging to four different and heterogenous collections which contain news agencies, scientific papers, and audio/video documentaries.
