Searching the Great Metadata Timeline: A Review of Library Metadata Standards from Linear Cataloguing rules to Ontology inspired Metadata Standards

Purpose: The purpose of this paper is to make a systematic review of the library metadata development history listing out the most significant landmarks and influencing events from Thomas Bodley's rules to the latest BIBFRAME architecture, compare their significance and suitability in the modern-day web environment. 

Design/Methodology/Approach: Four-time divisions were identified viz. pre-1900 era, 1900 to 1950, Post 1950 to Pre-Web era and Post-Web era based on pre-set information available to the authors regarding catalogue rules. Under these four divisions, relevant information sources regarding the purpose of the study were identified; various metadata standards released at different times were consulted. 

Findings: Library catalogue standards have undergone transitive changes from one form to another primarily influenced by the changing work environment and different forms of resource availability in libraries. Modern-day metadata standards are influenced by the opportunities provided by the World Wide Web towards libraries and works as a suitable base for data organisation at par with semantic web standards.

Research Limitation/Implications: Information organisation processes have gone towards a more data-centric approach than earlier document-centric nature in today's semantic web environment. Libraries had to make a move in this process, and modern-day guidelines in this regard bring the possibility of large scale discovery services through curated information resources.

Originality/value: The study discovers relationships between key events in the course of development of metadata standards and provides suggestions and predictions regarding it's future developments.
