| Abstract | One of the challenges in finding a suitable paradigm for defining software processes relates to the highly dynamic nature of software development. The actions required to carry out a given process are often dependent on detailed aspects of the current state. For example, the modules that need to be archived are just those that have been changed since they were last archived; the choice of archival method (i.e., source code control system versus local backup copy) depends on whether the module is in a steady state or still rapidly changing; use of certain debugging features is ruled out unless compilations were done with optimization disabled; and, many quite diverse factors influence the choice of relevant test cases to be run against a particular system version. The fact that development takes place, in part, through trial-and-error means that failures occur frequently, and recovery from failure must be accommodated. In spite of the programmer's best intentions, design reviews reveal areas needing rework, compilers find errors in source code, test cases fail, and tools sometimes exhibit bugs themselves.Powerful instantiation facilities represent one way to handle this type of dynamic behavior. A software project defines the process its programmers are to follow, and the actions taken by the programmers represent instantiations of this process. At an absolute minimum, instantiation involves binding parameters in the process definition to specific software objects in the environment. In this paper, we describe the relationship between instantiation facilities and the dynamics of process activities. First, we illustrate some limitations in instantiation mechanisms using a familiar paradigm: procedural definitions of processes. Then we describe a different approach to instantiation used in the AI planning paradigm. |

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.
