    Virtual product creation applications increasingly need data from heterogeneous PLM environments. Nowadays in common collaborations or in Virtual Organizations, this situation is even more complicated, because several organizational units and enterprises work together in a field of dispersed and heterogeneous data management systems. This paper introduces an integration solution to provide application systems with required data. It focuses on two use cases in virtual product creation. The first use case concerns with resource sharing in virtual organizations by grid computing in the context of product and simulation data management. The second use case deals with data preparation for virtual reality applications. Despite their differences, both use cases have many requirements in common for transparent data management. The realized concepts implement solutions for data collection, secure transports and authentication for users and systems in heterogeneous PLM environments. For this, it uses several standards, e.g. PLM Services, web services, X.509.

    Collaborations between SME are different than the traditional OEM-supplier chains. Here are other requirements in the focus of interest: Low costs are often more important than powerful and complex software products as well as flexibility to integrate with any kind of application is more necessary than already available integration solution for big enterprise application, which are only sporadic used in SMEs. Therefore the CoVES (Collaborative Virtual Engineering for SMEs) project followed a new approach for flexible integration of web applications in collaboration environments. The approach differs from the currently promoted service oriented architectures. This paper focuses on two technical aspects of the CoVES architecture: Mashup concept, which is a technology for a seamless integrati on of web applications, and Single Sign On for an easy access on the distributed data sources.

    Real-time interactive collaboration is the key to the success of organisations providing customised products/services to clients. This is especially the case when managers and engineers are on the move and need to communicate with and access data from not only the head office, but from other partners and clients engaged in the definition, development, delivery, or maintenance of the product/service. This paper presents technical developments of a collaborative environment built using mashup concepts to support SMEs in their virtual engineering work for three main use cases: manager on business trip; engineer on remote site; virtual team collaboration. An iterative living lab approach constituting systemic consideration of people, processes, and technologies was used. Findings indicate that for SMEs, simple integration of applications and services using mashup is a cheaper and more viable alternative for their collaborative virtual engineering work as compared to heavy investments in integration of applications using approaches such as service oriented architectures.

    Collaboration and mobility are two actual trends in new product development today. Due to the globalization of the economies and the outsourcing of specific tasks, companies have to work together as Virtual Organisations. However, the work environments of the collaborating people are very complex. In every company different processes and IT systems are used. Additionally, people are seldom at their company site, especially in small and medium sized companies (SME) the key personnel are often on the road. There they have no access to their digital files and information resources of their companies. This paper describes the architecture concept of a mobile collaborative environment addressing these problems.

    Virtual Reality leads Digital Product Development technology to a more effective and convenient way by presenting the product model in an immersive real 3D environment. Distributed VR even gives the possibility for partners to discuss the design of the product independent of their locations. This paper introduces the ongoing work with a Digital Product Development System with Virtually Cooperating Teams Using Optical Networks - ProVit, which aims at building up immersive telepresence systems for design review running over high-bandwidth networks. Video and audio streams are integrated in the virtual environment to support teleconference aspects of the distributed design review sessions. A network management system has been developed for the supervision, maintenance and processing of distributed setups, and network security.
