| Abstract | Adaptive middleware is a software for developing and executing distributed applications and can be reconfigured at runtime without its complete stop. The need of reconfiguration is usually triggered by changes in application's requirements and environmental conditions, to fix bugs or to extend the middleware's functionality. The development of an adaptive middleware still being a challenge due to the complexity of dealing with adaptation issues, such as how, when and where to reconfigure the middleware. Existing solutions to build adaptive middleware concentrate on the use of software mechanisms like aspect oriented programming and computational reflection to face the issues behind the reconfiguration. In this paper, we propose to reconfigure the middleware by moving adaptation decisions and actions from the middleware to an external and formally-based element. The whole adaptation process is performed based on the behavioural analysis of the middleware execution trace. In order to evaluate the proposed approach, we carried experimental experiments to check the effectiveness of the proposed adaptation mechanism and measure the overhead caused by the proposed adaptation mechanism. |

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.
