Metadata research is a new field of study that focuses on providing a variety of digital resources with semantic descriptions, where digital resources is the most common target. These related descriptions form the foundation for more progressive and improved services in a number of applications such as, location and search, customization, and automated information delivery. As a result, metadata research focuses not only on the creation of metadata description languages but also on the practices of creating, disseminating, evaluating, maintaining, and using metadata in a variety of settings and usage contexts. The objective of the Semantic Web is essentially built on Ontology, which has recently emerged as a knowledge symbol infrastructure for the delivery of mutual semantics to metadata. A truly multidisciplinary approach is required because the combination of metadata description methods and ontology engineering creates a new setting for information engineering with certain setbacks and promising applications. The purpose of this volume is to promote interaction among researchers from a variety of disciplines and to provide some fundamental insights for the activity of engineering systems dependent on metadata, semantics, and ontologies.
