| Abstract | In mobile field data collection, data gatherer requires to get geospatial information service to support in navigating to the right locations, describing context of observed object and providing thematic information for sampling or analysis. The framework how to get this information is subject to the variation in users with different levels of knowledge about information services, applications with different need of information, and limitations of field computing environments. In this paper, we present a new concept--field wrapper, which is an extension of wrapper concepts to the field data collection environments as a means of isolating the heterogeneity of field users, applications, and computing environments from infrastructure functions. The goal of our approach of field wrapper, which is as an important part of the mediator-based framework for collecting and using geospatial data in the field, is to enable any device with any user in the field to readily and easily interact with a larger computing infrastructure to search, retrieve, and get geospatial and other kinds of data. The key idea is to characterize the field environments to get an abstract field view. From this view, the system generates a field wrapper that facilitates query translation from user general request to the precise syntax statement accepted by mediator and result translation from native result to the specific result accepted by field user. |

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.
