Overview
SIST ISO 5428:1996 defines a Greek alphabet coded character set for bibliographic information interchange. Developed by the International Organization for Standardization (ISO), this standard specifies a set of 73 graphic characters, their coded representations, and provides a comprehensive code table with descriptive legends. The aim is to facilitate the accurate international exchange of bibliographic citations and their annotations when written in the Greek alphabet. This standard is integral for libraries, information agencies, and data processing centers that manage Greek bibliographic records and require consistent character encoding systems for data interchange.
Key Topics
- Character Set Composition: Includes 73 graphical symbols covering Greek capital and small letters, obsolete Greek characters, diacritics (such as grave, acute, diaeresis, circumflex), breathings, and punctuation marks relevant to Greek script.
- Coded Representation: Each character is assigned a unique code to support data processing and seamless integration with existing character sets, particularly when paired with the ISO 646 international reference character set.
- Diacritics and Breathing Marks: Essential for bibliographic accuracy, the standard details how diacritics and breathing marks are applied in Greek script, ensuring accurate textual representation.
- Integration Pathways: Provides guidance for implementation alongside ISO 646, ISO 2022, and ISO 2375 using internationally registered escape sequences.
- Applications Guidance: Includes explanatory notes for applying the character set, particularly regarding the positioning and combination of diacritics and breathings, vital for correct bibliographic data representation.
- Code Table and Legend: The standard offers visual and textual guides for each character's appearance and purpose within Greek bibliographic citations.
Applications
SIST ISO 5428:1996 is widely applicable in environments where Greek bibliographic information needs to be exchanged or archived digitally. Examples include:
- Library Cataloguing Systems: Libraries cataloguing Greek texts or references use this standard to encode and exchange records accurately.
- Bibliographic Databases: Ensures that databases handling multi-language bibliographic data including Greek can standardize encoding for reliable data interchange.
- Academic and Research Institutions: Facilitates accurate data exchange in the humanities and classical studies, where Greek sources and citations are common.
- Publishing and Archiving: Supports electronic publishing workflows and long-term archiving of Greek bibliographic materials with standardized character representation.
- Cross-border Data Exchange: Enables interoperability between organizations and software systems internationally, minimizing data loss or misinterpretation when Greek bibliographic information is shared.
