The technology of the 21st century has had no shortage of challenges for libraries, but it has also brought opportunities. Operating systems, databases, and application environments that can use cheap off-the-shelf hardware to scale and handle hundreds of millions of transactions were not developed for libraries. However, libraries have taken…

This overview of local library online systems that integrate several functions covers functional integration, benefits of integrated systems, turnkey systems, minicomputer and microcomputer-based systems, interfacing automated systems, types of interfaces, linking homogenous and heterogeneous systems, role of vendors, library applications, linking…

Describes the layered model of Open Systems Interconnection (OSI); summarizes the three upper and lower layers; and discusses data communications standards associated with specific layers. Architectural concepts are explored, including hierarchy and abstraction, levels of dialogue, internetworking, and end-to-end communication. OSI is compared…

Report on the status of automation within Library of Congress's Processing Services notes the positive effects of progress in cataloging activities, acquisitions activities, information retrieval, and dissemination of bibliographic products. Systems in operation, distribution services and products, and automation tasks not yet scheduled are…

Explains how the Directory Service (CCITT X.500/ISO 9594) became an international standard in response to the difficulties of keeping data on information network users current and accessible. Uses of X.500 are described, a technical overview is provided, its functions and protocols are assessed, and directory projects and products are discussed.…

Management of heterogeneous networks is complicated by the persistence of proprietary management schemes. The need for integration of network management capabilities is pressing. The International Organization for Standardization is developing standards for managing networks as part of the Open Systems Interconnection (OSI) effort. OSI management…

Reviews some of the projects and organizations concerned with promoting conformance and interoperability testing of Open Systems Interconnection (OSI) products and describes OSI products available from computer manufacturers and vendors. A list of references includes 57 articles that mention specific vendors and 11 general articles about OSI…

This document describes a proposed computer to computer protocol for electronic communication of digital information over a nationwide library bibliographic network. The protocol allows application tasks at one site on the network to converse with application tasks at any other site, regardless of differences in computer architecture or operating…

Traces the evolution of Open Systems Interconnection (OSI) from its genesis in 1978 and provides an overview of the various categories of standards, international standards organizations, the scope of standards, and the notations used to designate both the standards groups and the actual standards. (SD)

Discusses how various Open Systems Interconnection (OSI) application layer protocols can be used together, along with the Presentation and Session protocols, to support the interconnection requirements of applications. Application layer protocol standards that are currently available or under development are reviewed, and the File, Transfer,…

The edi conceptual model is being developed to define common structures, services, and processes that syntax-specific standards like X12 and EDIFACT could adopt. Open Systems Interconnection (OSI) is of interest to edi because of its potential to help enable global interoperability across Electronic Data Interchange (EDI) functional groups. A…

Describes the emergence of Open Systems Interconnection (OSI) as it relates to the U.S. Government Open Systems Interconnection Profile (GOSIP); defines GOSIP; and speculates about its future. Challenges facing GOSIP that are related to test policies and procedures, strategic and tactical planning, additional functionality, and international…

The IRVING Library Network provides state-of-the-art design, using a distributed packet switched network which implements parts of the Open System Interconnection Reference Model as defined by International Standards Organization. It provides gateway to other networks without disturbing local host systems and creates network language. Glossary and…

Describes the function of the Open Systems Interconnection (OSI) Z39.50 protocol, which allows for construction of information "servers"--i.e., resources attached to a computer communications network that can be accessed by client machines to retrieve information. The relationship of Z39.5 to other OSI protocols is explained. (23…

Recognizing that the fast-developing optical storage technologies provide a new dimension in publishing and information storage, retrieval, and distribution, this report examines the technical characteristics and capabilities of video and optical systems and the implications of this technology. The following aspects of optical disk systems are…
