| Abstract | Summary form only given. The very label "critical infrastructure" implies that such systems are important. They are. Within the US alone, there are approximately 28,600 networked Federal Deposit Insurance Corporation (FDIC) institutions, 2 million miles of oil/gas pipelines, 2,800 power plants with 300,000 production sites, 104 nuclear power plants, 80,000 dams, 60,000 chemical plants, 87,000 food processing plants, and 1,600 water treatment plants. And, this is just part of our national infrastructure. Add to this telecommunications and other "everyday" utilities and the scope is enormous. Most of these systems, alone, would qualify as a network-centric system; that is, a system of systems (SoS) whose totality provides additional functionality over each of the aggregate systems - in other words, an SoS is truly greater than the sum of each of its parts. For example, in the electric power grid, a utility can trade power daily (even hourly) with its neighbors, thereby assuring its customers of continued service. This connectivity provides robustness of service; unfortunately, it also provides an access point for interdependency which can lead to a cascading failure, - "the domino effect" that was seen in the 14 August 2003 blackout and numerous other incidents. With the realization that most network-centric systems are critical comes the acceptance that we need to make these systems more "trustworthy". Given the complexity and scale of these systems, zero-defect software (while admirable) is a daunting goal. Trustworthiness, however, may be achievable. By trustworthiness we mean that "as humans" we expect that the "non-human system" will behave in some reliable, predictable form with "reasonable" recovery techniques when problems are encountered. This paper highlights the network-centric system attributes which should be considered in any integration effort, as well as commercial off-the-shelf (COTS) encapsulation techniques, and other engineering trade-offs in a large-scale design and development effort |

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.
