| Abstract | An integrity specification language (ISL) based upon a form of interval temporal logic is defined and the framework for a logic of knowledge and beliefs about data integrity is developed. The intended purpose of ISL is for the design of integrity kernels in an office information system in which the dynamic evaluation of data integrity based upon partial knowledge and informed judgement relative to update request by clients, is required. ISL itself is described in an earlier paper and summarized in this paper. Beliefs in ISL are specified with a form of interval temporal logic and provide an extension of the Moser technique for formulating beliefs. The Clark and Wilson model designed to prevent fraudulent and erroneous data modification is subsumed. An integrity Characteristic Tuple (ICT) incorporates the notions of correctness, completeness, quality, timeliness and confidence is associated with each Constrained Data Item (CDI). An integrity system which includes extensions of the concept and function of the server architecture as defined in the Multimedia Office Server (MULTOS) project, is given. An integrity kernel is defined which incorporates an algorithm for the detection of faults in presumptions about data integrity based upon knowledge and beliefs. A simplified integrity kernel is specified formally and a corresponding sample server-client session is provided. |

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.
