| Abstract | Service-Oriented Architecture (SOA) is a paradigm for software development that has been increasingly adopted for factory automation. In SOA, services are independently developed and a central engine orchestrates their functional behavior according to the process workflow. If on one hand this orchestration is required to maximize performance and productivity, i.e., the software is required to be maximally permissive, on the other hand, implementing a service orchestrator is a creative task which cannot be totally automated. Furthermore, industrial processes tend to be very large, making it difficult to empirically provide in-advance quality guarantees for industrial SOA-based applications. In this paper, we show how maximally permissive and deadlock-free service orchestrators can be implemented. We propose a model for each activity that compose a SOA programming language. Then, we show how pieces of a workflow can be individually represented by combining activity models. Afterwards, we specify the logical behavior of the workflow in order to organize those pieces and reproduce the orchestration effect. By using controllability concepts, we finally compute from the orchestrator a version of it that formally provides certain quality guarantees. Examples illustrate the approach. |

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.
