| Abstract | Many applications are emerging which share the characteristic of being active, i.e. driven by asynchronous run-time events. The application areas include multimedia, cooperative working (such as conferencing), intelligent agent architectures, active database and support for user mobility. Prototype active applications are often developed from scratch as monolithic entities and are thus inflexible. Platforms which offer generalized support only usually deal with one application class in isolation.The thesis of this work is that active applications have generic requirements of a supporting platform. Rather than building each application as a monolithic entity, they can be composed of inter-connected sub-components called active objects. These objects can be used interchangeably in a plug-and-play architecture. This encourages on-the-fly application development and assists fast prototyping.This paper is supported by our implementation of a prototype distributed active application support platform. Our software is used to provide examples throughout. Section 1 describes the application requirements which a platform must be able to support. Section 2 describes the model for composing applications. Section 3 describes how a distributed programming platform has been enhanced for run-time object support and to allow new active object classes to be constructed easily. Finally, section 4 concludes. |

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.
