| Abstract | A Web service is defined as an autonomous unit of application logic that provides either some business functionality or information to other applications through an Internet connection. Web services are based on a set of XML standards such as simple object access protocol (SOAP), universal description discovery and integration (UDDI) and Web services description language (WSDL). Web services architectures are built on an insecure, unmonitored and shared environment, which is open to events such as security threats. Security concerns are the major barrier that prevents many business organizations from implementing or employing Web services. Based on the previous research in conflict of interest (CIR), this paper further introduces another important security concept called separation of duties (SoD) for Web services matchmaking process (WSMP). Next, this paper discusses the relationships between CIR and SoD in the context of matchmaking process. The paper then extends these two concepts into specifying and implementing CIR and SoD assertions in the newly developed WS-policy. WS-policy is an XML representation that provides a grammar for expressing Web services policies, to allow service locators to have a common interpretation of security requirements in the matchmaking process. Further, this paper presents a matchmaking algorithm for maximizing the level of SoD. Lastly, this paper also describes a prototype framework with "CIRService" and "SoDService" services for supporting CIR and SoD assertions in matchmaking process. |

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.
