Abstract | While there are more than 217 online pathway databases of different coverage and quality as of September 2007, our knowledge of human pathways is still far from complete. It has been challenging to develop pathway tools and database resources that could expand the coverage of existing annotated pathway data by integrating these resources both at the syntactic and semantic levels. While developing the Human Pathway Database (HPD), we use data warehousing techniques and a unified pathway data model to integrate a total of 1,895 pathways and 10,631 molecular entities from four different annotated and predicted pathway resources in human. HPD provides a comprehensive and integrated view linking human proteins, genes, RNAs, signaling reactions, gene regulatory events for future systems biology applications. We studied pathways in the database for their merging potentials and showed a preliminary pathway merging result as 2-D clusters. We also examined pathway scale and the distribution of pathway-spanning proteins, pathway characteristics that suggest small pathways and large pathways may still be under-represented in the HPD. We also found many proteins with important energy metabolism, cell growth, and cell differentiation functions span across vast number of pathways. The raw data for HPD can be queried at: http://discover.uits.indiana.edu:8340/spathway/s_pathway/. |

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.
