Abstract | Automated discovery and composition of Web services and the representation of service semantics required to automate these tasks are active research areas that play a large role in current work on service oriented architectures. In this paper, we investigate the feasibility of service composition powered by a consistency-based approach for candidate selection during composition. The modeling restraints imposed by the existing proposals for candidate selection often result in undesired implications in the form of unintuitive candidates during composition. We formulate a consistency-based candidate selection procedure, which uses specifications based on classical software engineering notations (UML and OCL), and use the selection procedure within a configuration based web service composition setting. The consistency-based matchmaking technique is robust in handling overspecified profiles, assumes a closed world by default and provides provisions to include 'nonexistence' semantics in addition to the standard formalisms. Finally, we formulate service composition as a constraint satisfaction problem (CSP) and provide a CSP based algorithm which uses the consistency-based semantic matchmaking scheme while enabling interactive operation. |

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.
