| Abstract | We describe the implementation of role-based access control in a data service integration system. Users in research or other projects may access a diverse collection of data sources but are to allowed access to only the part of the data collection that is necessary for their purposes. To simplify the administration of the access control, Role Based Access control is used, with the role hierarchy defined within and limited to each project. User queries to the integration system are analysed for their data access needs and those needs checked against the access control policies. The policies for the data held by individual data custodians can be managed and implemented by the custodian, or held in a central authorisation server in the integration system. The system is built around the Security Assertion Markup Language and eXtensible Access Control Markup Language standards. The access control architecture was developed for a health data integration system, but both the architecture and some of its components for authentication and authorisation could be readily reused in other similar systems. |

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.
