| Abstract | Computing becomes increasing mobile and pervasive today. Building context-aware computing has been drawing much attention from researches. However, it is still a complex and time-consuming task due to lack of appropriate infrastructure or middleware-level support. In this paper, we first propose a formal context-model based on ontology using OWL to realize semantic context representation, context reasoning and knowledge sharing, context classification and so on. Our context model captures various contexts by introducing a classification scheme; captures relationships between different context information by introducing dependency tag to the property associated with a specified context class; captures quality of context by annotating sensed context with extensible quality constraints. It also supports the use of different context reasoning engines to reason about various contexts so that applications can be given a notion of the confidence of different contexts before acting on it. And then, based on the context model, an architecture for building of context-aware services is presented. |

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.
