WGWSOA- Implementing Collaboration Services in a Middleware Infrastructure

Groupware applications are usually built without considering the need to interoperate with other already existing applications. WGWSOA (Web-based groupware Service-Oriented Architecture) is a service-oriented infrastructure, which was designed to support web-based distributed groupware development. To fulfill interoperability requirement it offers both common and specific middleware services which need to be readily interoperable. On this project, a collaboration services has been developed aimed to evaluate interoperability aspects. However, fulfilling groupware interoperability, while considering only data and procedures, is not enough in this context. This paper describes WGWSOA middleware infrastructure, as well as the results obtained throughout its service development. In addition, requirements related to semantic interoperability are discussed aiming to enhance distributed groupware applications development as well as their execution.
