Harvesting ETD Metadata from 'Shodhganga' to National Digital Library of India: present scenario and implementations

By using ICT, there has been a dramatic change in the world of e-learning and learning resource materials. Through the OAI-PMH, the records data about information sources allows an initial assessment of compatibility. It provides an avenue for merging information or for exchanging information between systems. Integration of Indian ETDs based on metadata has received wide attention for better management and utilization. This study explores the current state of metadata harvesting of Shodhganga or Indian ETD repository to NDL platform. One of the fundamental aims of NDL (National Digital Library of India) is to share the e-resources of multiple academic institutions and other resources across a common platform. One of the major objectives realized through this activity include increased visibility and enhanced discoverability of resources. Based on the variation in contents, metadata schema in NDL platform has been categorized into three basic classes, they are Generic Metadata, Educational Metadata and Thesis Metadata. Thesis Metadata fields like researcher, advisor, degree, etc. This Thesis Metadata standard has been used Qualified DC to harvesting the national ETDs to NDL repository. Some popular metadata schema of national and global ETDs repositories, such as ETD-MS (NDLTD) and UK-ETD (EThOS) also compared in the paper.
