Abstract

Standards are important for quality and interoperability in any system. Bibliographic record creation standards such as MARC 21 (Machine Readable Catalogue), CCF (Common Communication Format), UNIMARC (Universal MARC) and their local variations, are in practice all across the library community. ILMS (Integrated Library Management Systems) are using these standards for the design of databases and the creation of bibliographic records. Their use is important for uniformity of the system and bibliographic data, but there are problems when a library wants to switch over from one system to another using different standards. This paper discusses migration from one record standard to another, mapping of data and related issues. Data exported from CDS/ISIS CCF based records to KOHA MARC 21 based records are discussed as a case study. This methodology, with few modifications, can be applied for migration of data in other bibliographicformats too. Freeware tools can be utilized for migration.

Abstract

CDS/ISIS is a powerful and popular software package for managing computerized bibliographic data. It is developed and maintained by UNESCO since 1985. It is free software available in binary form for MS-DOS, MS-Windows, Unix, and Unix-based operating systems like Linux. It is used by many libraries and organizations in many countries to maintain their Online Public Access Catalogues (OPACs) and other bibliographic databases. With the advent of the Internet and Web technologies, publishing the content of databases on the Web provides a round the clock access to the content from any PC with Internet access. Some CDS-ISIS databases are published on the Web, but many are still on standalone systems or on local area networks. Interoperability is the key for the efficient dissemination of information to end-users. The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) provides a technical framework for interoperability of OAI-compliant digital libraries (UNESCO. 2004). However, CDS/ISIS databases are not OAI-compliant. In this paper, we describe a simple approach, to make CDS/ISIS OAI-compliant. It is based on printing CDS/ISIS records in an OAI static repository format.

Abstract

Language technology is undergoing a great change and within a few years languages of the world will embark on OTF (Open Type Font) Technology. Major operating systems have already started embedding Asian languages using OTF. Being a major bibliographic DBMS, CDS/ISIS cannot ignore these developments that have taken place in text processing. This paper looks at the ideas behind Unicode and OTF and examines future developments of multilingual information systems. The Unicode is a minimalist encoding which includes currently all major scripts in use and allows easy migration from an existing encoding scheme to it. Indic language computing will be tremendously benefited from the development of OTF in compliance with Unicode. CDS/ISIS should be made Unicode compliant by utilizing the shaping and encoding engine on various operating systems so that it can be effectively utilized to develop and distribute local information systems using vernacular scripts. The source code of CDS/ISIS may be made available under a free software license, allowing the evolution of the package in a free and socially useful manner.
