Resource discovery with evolving tuples

Content Provider ACM Digital Library
Author Julien, Christine Stovall, Drew
Abstract Pervasive computing environments present new challenges that hinder traditional approaches to software engineering. In this paper, we tackle one such challenge: the need of pervasive application developers to have access to constructs that enable resource discovery in dynamic environments. We first define the evolving tuples model, a novel extension to traditional tuple spaces that allows applications to embed context-aware adaptation directly in structures traditionally used for distributed coordination. The behavior applications embed in evolving tuples can subsequently be used by discovery queries to allow environmental characteristics to directly impact the results of discovery. Our approach minimizes the amount of infrastructure that must be available to support discovery by embedding the discovery functionality almost exclusively within the tuple and makes the resource discovery process transparent. At the same time, our model retains many of the benefits of traditional tuple space approaches, namely providing content-based coordination that is easy for developers to understand and implement. The evolving tuple's inherent flexibility also allows resource discovery to adapt to the changing resources, applications, and environments.

About National Digital Library of India (NDLI)
NDLI logo

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.
