| Abstract | While research in sensorwebs often focuses on extremely low-power, inexpensive sensors coupled with ad hoc, occasionally-connected networks, the recent tragic tsunami associated with the Sumatra earthquake leading to the loss of more than 280,000 lives in the Indian Ocean demands a fresh look at networks and grids on a global scale often involving highly sophisticated sensors. The extraordinary growth in network bandwidth coupled with initiatives such as the not-for-profit National Lambda Rail has enhanced grid computing and grid storage technologies making a truly global sensorweb not only possible, but also imperative. The same system lowers most barriers to scientific research on vast amounts of new data and lowers the costs of operations and maintenance. The Earth and planetary sciences are moving toward an interactive global observation capability necessitating a new generation of cyberinfrastructure. At UCSD and Scripps NSF ITR projects including ROADNet, LOOKING, and the OptIPuter are prototyping real time control of remote instruments, visualization of large data objects, metadata searching of federated data repositories, and collaborative analysis of complex simulations and observations. A single-purpose national or global warning system, for tsunamis for example, is nearly impossible to maintain because of the time scales of major events -- decades to centuries. However, a broad, scientifically based, multipurpose system can be maintained and will grow as new technologies become available and new approaches in cyberinfrastructure replace the old. |

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.
