Distributed manufacturer services to provide product data on the web

摘要

Digital planning methods are changing the needs of construction stakeholders. It should be as easy as possible to compare product data from different manufacturers and integrate them into the planning model without detours. Web technologies not only offer great potential to enhance existing ways of working, but also open up new business models for product manufacturers in the service and IOT domains. However, manufacturers have a legitimate interest to retain control over the disclosure of their product data. Therefore, it is often only available offline and on demand. Of technical interest are therefore solutions, in which a large part of the data autonomy and access control remains on the side of the manufacturer, but the project planner is allowed to search the product data of all manufacturers like an interconnected system. Frequently, such a searchability is ensured by a uniform data schema and storage of the data in a central storage location, a so-called data warehouse. Nonetheless, this stands in contrast to the natural interest of the manufacturer for data sovereignty. This paper focuses on systems that can replace centralized data storage with distributed data management on manufacturer-owned servers, without losing accessibility for planners. Manufacturers should have as much freedom of implementation as possible when establishing the security concept, modeling their data and integrating the proposed approach into their operating procedure.
