Abstract | SOAP is used to communicate with Web services. It defines the a messaging framework (the envelope), encoding rules and a binding protocol over the HTTP protocol. However SOAP, as it is, does not deal with conversations. To provide full interoperability, clients need to not only know the correct data formats to pass, but also the conversation level protocol involving those messages for any required Web service. This must also include the valid responses, where multiple responses are possible, and the starting and ending states of the conversation.This paper describes an XML-based conversational protocol for Web services. Each server site publishes details enabling client agents to interact with the server. This involves the publication of protocol specifications representing a finite state machine (FSM). A client agent downloads this specification, validate it for correctness, and then implement the protocol dynamically, as a state machine. This can be viewed as a negotiation of protocols where the client negotiates to implement all requirements of a server. |

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.
