Operative Models for the Introduction of Additional Semantics into the Cooperative Planning Process

Abstract

According to the State-of-the-Art building information is described by standardized evaluated models like the Industry Foundation Classes (IFC). Instances of evaluated models are stored either in documents that are frequently cloned and exchanged or in model servers that allow for sharing data between the actors involved. In the cooperative planning process this approach has considerable shortcomings concerning model complexity, implementation effort, model transformation and model semantics. In the solution approach presented the currently used evaluated models are complemented by additional semantics. This approach is denoted as operative modeling. Here, the native application models remain unchanged and the operations applied are stored using a simple, standardized language. Because operative models have additional semantics they could be a solution in the fields of data exchange, version management and long term compulsory archiving.
