The Indira Gandhi National Open University in its 22 years of existence has emerged as the single largest University in the democratic world. It serves the educational aspirations of more than 1.8 million students in India and 32 other countries through the 21 Schools of Study and a network of 58 regional centres, more than 1804 study centres/tele-learning centres and around 46 overseas centres. The University offers 138 Certificate, Diploma, Degree and Doctoral programmes comprising around 1300 courses. Conventional teaching learning methods are being effectively supplemented with Information and Communication Technology and Satellite-based teaching-learning systems.

The University provides multi-channel, multiple media teaching-learning packages in the form of self-instructional print and audio/ video materials, radio and television broadcasts, face to-face counselling/tutoring, laboratory and hands-on experience, video conferencing, interactive radio counselling, interactive multimedia CD-ROM and internet-based learning. Apart from the print based self instructional material, the educational programmes are reaching over 5 million homes through the Gyan Darshan Channels, via the DTH (Direct-To-Home) platform and webcasting. The University is now gearing towards the development of interactive multimedia content and learner support through web-based platforms.

The e-Learning market is booming world over and is predicted to follow an upward swing with more and more institutions, organisations and individuals implementing and adapting to this mode. The power of e-Learning lies in its potential to provide the right information to the right people at the right time and place. With advent of Information and Communication Technologies (ICTs), the delivery of educational programmes has witnessed a paradigm shift from print based teaching-learning to e-Learning. The learners having access to the internet and those who have adapted to learning through computers have shown their preference for e-Learning over print.

Web that gives information access to users who are physically remote from resources is emerging as a democratising, emancipating, empowering force facilitating self-publishing, knowledge sharing and peer-to-peer networking. It has now shifted from being a medium, in which information was transmitted and consumed, into a platform, where content is created, shared, remixed, repurposed, and passed along. In the same spirit e-Learning has moved from being merely a content repository and emulating classroom teaching to more dynamic concepts of Social Networking, Do-It-Yourself (DIY), Personal Learning Environment (PLE) and Mobile Learning.

The ICT led initiatives in the form of e-Learning, online student support, digital repositories, open source courseware, etc. are now part and parcel of the Open and Distance Learning (ODL) systems. The earlier generations of ODL has given way to new generations which are ICT dependant for dissemination of knowledge without compromising on the quality and being more cost-effective.

Realising the potentials of e-Learning to reach out the un-reached, IGNOU has recently embarked on a few major initiatives towards developing online learning environment for distance learners. eGyanKosh: a national digital repository, e-Learning platform for LIVE (Library and Information Virtual Education), PAN- African E-Network and Sakshat a one stop education portal of the Ministry of Human Resource Development (MHRD), are some major initiatives of the University in this direction  have been discussed here.

eGyanKosh: A National Digital Repository of learning resources

eGyanKosh is an effort towards developing a national digital repository of learning resources. Over the years, a vast amount of self instructional materials, audio and video programmes have been generated by the open and distance learning (ODL) institutions in the country. Huge wealth of structured knowledge is available which is very difficult to access and reuse. This results in duplication of efforts in developing learning materials and wastage of valuable resources. These learning materials have restricted use by the registered programme specific audience only. Some of the materials especially the audio visual ones do not even reach the targeted audience.  Considerable amount of money is invested for the purpose but most of the materials remain under-utilised. Moreover, the audio visual programmes stored in analogue form have a limited life span. Keeping these issues in mind, eGyanKosh, a national digital repository was initiated by IGNOU to store, index, preserve, distribute and share the digital learning resources developed by the ODL institutions in the country.

In the first phase IGNOU course materials are being digitised for uploading on the repository. This will be followed by incorporation of course contents of other Open and Distance Learning (ODL) institutions in the country.

At present a centralised model of implementation is being carried out where servers are located at a central location in the IGNOU campus and content is being digitised and uploaded in the eGyanKosh unit of the University. There are plans to move on to the decentralized structure where the other ODL institutions will be participating in uploading material on the repository. The content and the metadata will be moderated at IGNOU before uploading on the repository. The long term plan, however, is to implement a distributed model once the ODL institutions have acquired necessary infrastructure and expertise in developing repository at their own end. In the distributed model the repository will have an interoperable architecture with the facility of cross collection federated searching.
