| Abstract | Examines and details the motivations and design of a constraint specification language (CSL) for user-defined constraints. Many approaches to constraint programming are based on, as well as extended from, the logic programming paradigm. Some of the better-known constraint logic programming languages and systems are CLP, PROLOG III and CHIP. In these languages, unification in conventional logic programming is replaced by constraint satisfaction. Numerical constraints are usually focused on. The technique of constraint satisfaction is therefore hidden from the user. The motivation for developing CSL is not in adding to the myriad of available constraint programming languages, neither is CSL a complete stand-alone package for solving constraint satisfaction problems (CSPs), though it has a mode that allows it to do so. Its main purpose is simpler: CSL serves to enhance the constraint satisfaction aspect of these languages by providing an expressive algebra for describing current definitions of general CSPs as well as extended versions. The descriptions specified in the CSL syntax are efficiently compiled into data structures that are transparently accessed by algorithms normally only associated with binary CSPs. |

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.
