| Abstract | The value of service oriented architectures has been demonstrated in several studies. A key aspect of the advantage of web services is their orchestration into complex business workflows. The Organization for the Advancement of Structured Information Systems (OASIS) has recently approved an industry-wide standard for workflow specification, the Business Process Execution Language (BPEL). The Open Geospatial Consortium (OGC), a member of OASIS, has adopted BPEL for its series of interoperability experiments. This paper presents a study concerned with the use of ontology in assisting geospatial web service orchestration. A methodology for calculating the degree of suitability of various candidate workflows is proposed. The implementation of a prototype plug-in for Eclipse-based BPEL editors is discussed. The proposed system presents candidate workflows based on semantic descriptions of feature, coverage and processing services. An evaluation of the system, based on a workflow involving a variety of geospatial web services is also presented. |

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.
