The application belongs to the technical field of UML model fragment reuse, and relates to a UML model fragment reuse method, which filters out non-packable elements and external reference elements according to UML elements selected or input in other manners, recursively queries reference elements associated with valid packable elements, and completely collects all elements required to express a UML model fragment, thereby solving the core problems that the prior art cannot completely process associated metadata and reference relationships and cannot reuse UML model fragments across scenes. In addition, the UML model fragment template created is stored in an EMF resource, and relies on the standardized storage characteristics of EMF, so that the template can be conveniently managed and called across projects, and is compatible with other modeling tools. Finally, the UML model fragment is conveniently reused, and modeling efficiency, model quality and maintainability are significantly improved.
