13、ntation Profile 1, ANSI/NISO Z39.83-2-2008. It is included for information only.) About This Standard This Implementation Profile has been developed to provide a practical implementation structure for the NISO Circulation Interchange Part 1: Protocol (NCIP). The Foreword to Part 1 provides a complet
14、e description of the reasons for the NCIPs development and the reasons for describing the physical implementation of the NCIP within an Implementation Profile rather than within the NCIP itself. In brief, the committee decided that this approach would improve the extensibility of the NCIP. This appr
15、oach also allows the community of application providers and users to adapt the implementation profile to changing technology. Version 2 includes radical changes to the protocol. It is not backward compatible with version 1, as it is based solely on an XML Schema. The version 2 changes build on chang
16、es made since original publication of NCIP and known collectively (if inaccurately) as version 1.01, the version several implementers are already using. There are a few other changes that also break backward compatibility. The most significant are in error handling and extensibility. A complete chan
17、ge list for version 2 (including the incorporated changes from version 1.01) is posted on the NCIP website: www.ncip.info. Principles In making decisions about this Implementation Profile 1 the committee examined ways to facilitate rapid and widespread implementation of the NCIP. Two goals drove dec
18、ision-making: make it easy for service providers to use NCIP in a variety of applications and make it easy for them to build those applications quickly. From these goals, the committee developed the following principles: Use technology that is widely supported. This dictated choosing options that of
19、fered the most robust support for application development. Stay with the curve. NCIP will be embedded in applications that last an average of several years, if not longer. This requires choosing technology likely to stand the test of time. In some cases, this meant rejecting very promising technolog
20、y when it was not clear that the technology would be widely adopted. As noted below, the committee deliberately built bridges to emerging technology where possible. These were judgment calls, not matters of precise calculations. Several areas deserve particular mention: Message Encoding and Structur
21、e The committee chose Extensible Markup Language (XML) over ASN.1/BER, which has been widely used in library applications. XML is supported by a large number of organizations and tool providers. This provides implementers with a choice of tools. In addition, the expectation is that it will be the do
22、minant encoding method used in Internet communication. This widespread usage will help those using the NCIP for library applications to connect libraries to the broader stream of information services available in todays electronic environment. Extensibility The Foreword to Part 1 discusses the varia
23、tion in circulation practice and the need for a flexible mechanism for supporting variation in practice and local policy. The business rules that enforce these policies often use enumerated data types to characterize those policies. In some cases these are defined in existing authoritative lists; in
24、 other cases, the lists are maintained locally by an agency or a consortium. In either case, the expectation is that the definition of the enumerated types will be independent of the XML Schema definition for NCIP messages. The committee has adopted a data structure that allows for an optional Schem
