TL;DR: This paper introduces the reader to the key role that metadata can play for managing various digital media, often also called new media, such as image, audio, and video in information systems.
Abstract: This paper introduces the reader to the key role that metadata can play for managing various digital media, often also called new media, such as image, audio, and video in information systems. We present different views on how metadata can be modeled, classified, extracted, managed, and applied, to support a convenient handling of digital media. We discuss various issues on the role of metadata from different viewpoints: the application scenario perspective, the media processing perspective, and the metadata type and classification perspective. We also look at the world of standards for handling metadata. Finally, the chapter gives an outline of the book and provides a coherent view over all the chapters. Each of the chapters in the book and its main issue in the field is introduced in brief with respect to the concepts and issues discussed in this paper.

TL;DR: In this paper, the authors present a computer-implemented method of converting first metadata to second metadata using a mapping and custom exits, where the metadata is at the M1 level and the mapping is generated based on information at M2 level.
Abstract: In one embodiment the present invention includes a computer-implemented method of converting first metadata to second metadata using a mapping and custom exits. The metadata is at the M1 level and the mapping is generated based on information at the M2 level. The custom exits provide programmable mapping rules in addition to the mapping. In this manner, metadata created in one modeling environment may be used in another modeling environment.

TL;DR: This work presents a three-level architecture comprising of the ontology, metadata and data levels for enabling correlation of information at a semantic level across multiple forms and representations for answering a user query.
Abstract: Huge amounts of data available in a variety of digital forms has been collected and stored in thousands of repositories. However, the information relevant to a user or application need may be stored in multiple forms in different repositories. Answering a user query may require correlation of information at a semantic level across multiple forms and representations. We present a three-level architecture comprising of the ontology, metadata and data levels for enabling this correlation. Components of this architecture are explained by using an example from a GIS application.

TL;DR: The paper concludes with a proposal for the specification of completeness levels as compliancy requirements for learning-related services or processes.
Abstract: Completeness of e-learning objects metadata records becomes a key requirement for learning object repositories, since these repositories are called to play a central role in automated approaches to e-learning. Nonetheless, metadata creation is a time-consuming and laborious process. These two factors may eventually result in incomplete and poorly structured metadata. In this paper, the completeness of learning object metadata of samples obtained from the MERLOT and CAREO repositories is analysed from that viewpoint, using the IEEE LOM standard as a reference framework. The paper concludes with a proposal for the specification of completeness levels as compliancy requirements for learning-related services or processes.
