| Abstract | In practice, a pure top down and refinement based development process is not applicable. A more iterative and incremental approach is usually applied with respect to changing requirements. We call such an approach an evolutionary approach. As existing methodologies rely on refinement concepts, they do not support an evolutionary development. We present the basic concepts of a suitable overall methodology based on componentware and software evolution. We classify the difference between refinement steps and evolution steps in a document based development methodology. We propose an evolutionary development process during system design. To support this process best, we need to be able to model and track the dependencies between the various development documents. Currently, there is no adequate modeling technique available. To close this gap, we introduce the concept of requirements/assurance contracts. These contracts can be rechecked whenever the specification of a component evolves. This allows the impacts of that evolutionary step to be determined. Developers are able to track and manage the software evolution process. A short example shows the usefulness of the presented concepts and introduces a description technique for requirements/assurance contracts in componentware. |

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.
