| Abstract | This paper introduces the concept of "interaction points" which are currently used in an experimental programming environment, the In-process Modular Programming (IMP) platform. IMP is a Microsoft COM-style platform designed specifically for building component-based applications in real-time and embedded environments, and used for research prototyping at Lucent Technologies, Bell-labs. Interaction points serve as a unified abstraction for a wide range of inter-component communication mechanisms. They allow the programmer to easily take advantage of available operating system level mechanisms such as semaphores, shared memory, spinlocks and I/O buffers, in order to realise advanced inter-component communication paradigms. They excel in supporting broadcast and multicast communication, which are often difficult to realise with point-to-point communications such as those provided by conventional program function calls. In addition to supporting operating system mechanisms, interaction points also provide a mechanism for building re-useable custom communication facilities that are not themselves, considered worthy of componentisation. Finally, the use of interaction points helps to maintain an explicit definition of communications on component-interfaces and thus avoid problems of ill specified 'hidden' component interactions that often lead to problems during third party re-use. |

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.
