| Abstract | In this paper we describe an industrial application of formal methods. We have used model checking techniques to model and formally verify a rather complex software, i.e. part of the “safety logic” of a railway interlocking system. The formal model is structured to retain the reusability and scalability properties of the system being modelled. Part of it is defined once for all at a low cost, and re-used. The rest of the model can be mechanically generated from the designers' current specification language. The model checker is “hidden” to the user, it runs as a powerful debugger. Its performances are impressive: exhaustive analysis of quite complex configurations with respect to rather complex properties are run in the order of minutes. The main reason for this achievement is essentially a carefully designed model, which exploits all the behaviour evolution constraints. The re-usability/scalability of the model and the fact that formal verification is automatic and efficient are the key factors which open up the possibility of a real usage by designers at design time. We have thus assessed the possibility of introducing the novel technique in the development cycle with an advantageous costs/benefits relation. |

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.
