Application Level Protocol Development for Library and Information Science Applications. Volume 1: Service Definition. Volume 2: Protocol Specification. Report No. TG.1.5; TG.50.
Aagaard, James S.; And Others
This two-volume document specifies a protocol that was developed using the Reference Model for Open Systems Interconnection (OSI), which provides a framework for communications within a heterogeneous network environment. The protocol implements the features necessary for bibliographic searching, record maintenance, and mail transfer between end-user application processes in library and information sciences. The specifications result from a grant to develop application and presentation level protocols to support the Linked Systems Project that was established among the Washington Library Network, the Research Libraries Group, and the Library of Congress. Volume 1 provides an introduction, a description of the OSI Reference Model, and an overview of the model application layer. Facilities of the application service are defined, including those for connection establishment and termination, information retrieval, record maintenance, mail, interrupt, and settings. Service descriptions are provided and the service specification technique explained. Service element specifications, interface event sequences, and parameters for service elements are outlined. Volume 2 provides an introduction and overview of the protocol, explains the protocol specification method and notation, and details the formal specification of the protocol and 33 protocol data unit (PDU) formats. A 59-item reference list is included in both volumes. (LMM)
