- Abstract
- The entry provides an overview of the data content standard, Cataloging Cultural Objects (CCO), developed by the Visual Resources Association (VRA), and published in 2006 by the American Library Association (ALA). CCO fills a gap in the array of descriptive standards by providing guidelines for visual resources curators, museum documentation specialists, archivists, librarians, or anyone engaged in the documentation of works of art and architecture, objects of material culture, and their images. The entry begins by placing CCO within the context of object and visual image cataloging and the broader framework of data content standards. Following the organization of the guide, which is divided into three parts, General Guidelines, Elements, and Authorities, it summarizes the main features of CCO. Finally, it evaluates CCO in terms of its suitability for use by the metadata communities that form its intended audience, and its sustainability.

- Abstract
- In this chapter we describe methodologies for representing information in digital libraries in order to support efficient search and content-based retrieval, and we focus our attention an image repositories. We identify different abstraction levels at which content can be specified. We discuss how simple objects can be defined as connected regions that are homogeneous with respect to pixel-level, feature-level, semantic-level, and metadata-level characteristics. We describe how information can be efficiently represented at these different levels, how a user can specify content, and what mechanisms can be used to perform the search. We present techniques for combining image representation, in particular image compression, with image-processing operators designed for content-based searches. On the one hand this approach makes it possible to extract and index content at database ingestion time even when the data volume is large. On the other hand it allows the system to retrieve simple objects for which definitions are provided at query time and that have not been pre-extracted and preindexed. Simple objects, however, are not sufficient to describe the richness of image content. We rely an the concept of composite object, a collection of simple objects satisfying a set of relations, to specify complex queries. We describe algorithms for retrieving composite objects from image databases. This article is organized as follows. The next section contains an introduction to digital libraries and a description of four application areas. The aspects of compression that are relevant to progressive retrieval are discussed in the section attached. The subsequent section provides a brief introduction to content-based searches, the standard approach to query specification in multimedia databases. Our definition of content in terms of simple and composite objects is contained in the following section. Simple objects can be defined at multiple abstraction levels; fundamental concepts, content-extraction methodologies including progressive techniques, and indexing methods are discussed in the next section. Simple objects can also be defined simultaneously at multiple abstraction levels, and aggregated to form composite objects. The semantics of both types of objects and the techniques required to search for them are the subject of the section after that. The final section contains the conclusions.

- Abstract
- Although classification has been an important aspect of astronomy since stellar spectroscopy in the late nineteenth century, to date no comprehensive classification system has existed for all classes of objects in the universe. Here we present such a system, and lay out its foundational definitions and principles. The system consists of the "Three Kingdoms" of planets, stars and galaxies, eighteen families, and eighty-two classes of objects. Gravitation is the defining organizing principle for the families and classes, and the physical nature of the objects is the defining characteristic of the classes. The system should prove useful for both scientific and pedagogical purposes.
