摘要：Web services are the backbone of WISDOM system, an information and visualisation system supporting decision makers in the fields ofwater related management processes based on open source technologies. They enable the distributed and loosely coupled, componentbased architecture of the system. In cooperating OGC compliant web services for data access, visualisation and data processing thesystem is extendible to external data resources and other proprietary software solutions. The base idea behind the designed andprototypically implemented WISDOM techniques is the orchestration of decoupled web resources representing data sets and functionalityto model more complex business processes quite easily. The system covers most aspects of administrative business processes includingspatial and non-spatial data ingestion and dissemination, necessary data processing and visualisation techniques. In combination with asemantics enabled data management WISDOM system is capable of producing value added information products to water managementrelated tasks autonomously. These compound data and processing resource chains are implemented to facilitate certain identifiedbusiness processes in regional administration. Clients like data and information explorers supporting manual interaction as humanmachine interfaces or automated data access of value adding operations accomplish, respectively trigger these integrative chains. As anexample the same data and processing infrastructure is used to visualise data in map clients as WMS or access data as WCS, resp. WFSfor further processing which can furthermore trigger additional actions like feeding reports or requesting auxiliary data
