Developing Collaborative Editing Applications using Web Services

For instance, a CEA for developing a software product, may require specialised and cheaper services provided by different software engineers and programmers, which are remotely located and connected via the Internet. This enable companies such as Microsoft to acquire some services from programmers in India, while others from China. Using WS technologies and protocols such as SOAP, WSDL, and UDDI, systems can easily be integrated and utilised for a variety of services in ComputerSupported Cooperative Work (CSCW) applications, such as electronic conferences and meetings, collaborative CAD and CASE applications, and collaborative documentation systems. ABSTRACT This paper presents a new approach for developing collaborative editing applications (CEAs) using Web Services technologies and protocols such as SOAP, WSDL, and UDDI. In the proposed approach, CEAs can be developed using different services available from various autonomous and heterogeneous collaborative editing systems which are distributed across the Internet. A new transactional approach is also presented so as to ensure the consistency and correctness of CEAs. Transactions ensure the concurrent execution and reliability of CEAs during systems and communication failures.
