| Abstract | An information service system must be designed such that service providers (SPs) and users can supply and use the information service in a timely and reliable way, while each of the SPs has their own mission and each of the users has their own service preferences. Moreover, the mission and the user preferences change dynamically. As the network becomes larger, it may include the failure, maintenance and addition of nodes. An assurance system, called the FIF (Faded Information Field) system, is proposed to achieve real-time properties and reliability of the service provision and utilization under evolving situations. In FIF, push-type/pull-type mobile agents are generated for the SP and the user to autonomously allocate information to the nodes and to utilize the information at these nodes. The push-type mobile agent, originating at the SP, carries the SP's information to be autonomously allocated to the nodes, but the information gradually fades in the process of node-to-node movement. The fading part of the information is selected at the node on the basis of the user preferences. The more highly preferred information is replicated at more nodes on the network. The pull-type mobile agent, being sent out from the user, can autonomously search for the necessary information among the nodes. Then the user can reliably and timely obtain the preferred information at the local nodes in the FIF. The autonomous fading/navigating technologies make it possible to adapt to large and rapidly changing situations in the services without stopping the system and also to satisfy the assurance of information provision and utilization. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
