Institutional Repositories (IRs) are an effective way of managing and disseminating institutions’ in scholarly communication. More specifically, an IR enhances the visibility and discoverability of the content and validates the repository’s importance. Knowledge Organisation System (KOS) strengthens the digital content organisation, connects users with collections, and improves information retrieval functionalities. This paper investigates the present status of user interface features and incorporates KOS in the institutional repository of technical institutions, restricted to Centrally Funded Technical Institutions in India. A group of twenty-four web-accessible institutional repositories was identified, and their KOS and user interface features were evaluated. It was found that user interfaces of all IRs under study comply with essential search and navigation functionalities, such as simple and advanced search, browsing, faceted or filtering approaches, and integration with multiple KOS. Only a few of them include complex KOS, such as control vocabulary. All repositories show their search results in both normal-text and metadata views. Some have specific display features, such as highlighting the query or displaying a thumbnail. Google is one of the most popular search engines that indexes IR content for visibility and discoverability, and approximately 90 per cent of repositories are linked with NDLI. Global visibility and impact participation are moderate, and they require attention. [ABSTRACT FROM AUTHOR]

The Open Archival Information System (OAIS) reference model ensures that an organisation charged with the task of preserving information (here, digital information) makes it accessible to the designated community in the long-term. It elucidates the functions and processes so as to promote interoperability amongst digital libraries, archives and other institutions and provides a framework for describing and comparing different long-term digital preservation strategies and techniques. This paper discusses what it means to be OAIS compliant for the pilot institutional repository at the Indian Institute of Geomagnetism (IIG). It maps the six entities of an OAIS-compliant repository (Ingest, archival storage, administration, data management, preservation planning and access) onto a pilot institutional repository (IR) structure of the IIG. It discusses the policies and procedures required for effective OAIS implementation within the IIG institutional repository and ways to effectively develop these based on experiences from abroad. The paper further assesses how the institute's operational structure can be informed by the OAIS and vice versa. It establishes the role of the preservation service provider for the IIG IR, and explores the potential for interaction between IIG and such service providers.It identifies the rights and responsibilities, services and actions, and apportions these between the IR and the third-party preservation repository service. It identifies the tools and develops the processes to implement the preservation services and actions. It is expected that this study can be of use to other organisations that might want to undertake implementation of the OAIS reference model. [ABSTRACT FROM AUTHOR]
