| Abstract | In this paper we present Trishul-UCON (T-UCON), a DRM system based on the UCON_ABC model. T-UCON is designed to be capable of enforcing not only application-specific policies, as any existing software-based DRM solution does, but also DRM policies across applications. This is achieved by binding the DRM policy only to the content it protects with no relations to the application(s) which will use this content. Furthermore, to guarantee that the policy is continuously enforced, we designed T-UCON as a JVM-based middleware that mediates the usage requests of any Java application to the protected content. Each request is granted or denied according to the content policy. We illustrate the unique features of T-UCON by using typical examples of DRM policies such as the pay-per-use and the use only N times scenarios. Preliminary results on the overhead of our solution are also provided. |

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.
