| Abstract | Contract-based design enriches a component model with properties structured in pairs of assumptions and guarantees. These properties are expressed in term of the variables at the interface of the components, and specify how a component interacts with its environment: the assumption is a property that must be satisfied by the environment of the component, while the guarantee is a property that the component must satisfy in response. Contract-based design has been recently proposed in many methodologies for taming the complexity of embedded systems. In fact, contract-based design enables stepwise refinement, compositional verification, and reuse of components. However, only few tools exist to support the formal verification underlying these methods. OCRA (Othello Contracts Refinement Analysis) is a new tool that provides means for checking the refinement of contracts specified in a linear-time temporal logic. The specification language allows to express discrete as well as metric real-time constraints. The underlying reasoning engine allows checking if the contract refinement is correct. OCRA has been used in different projects and integrated in CASE tools. |

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.
