The BOM-based simulation model component is the implementation of the description of BOM, which is regarded as the reusable interplay information package for rapidly building simulations or federation. With the introduction of XMI standard provided by MDA to interchange models, it is possible for the interchange of HLA simulation model components to be applied to different platforms, different programming languages and various domains on the two levels of simulation components modeling and implementation. So the reusability and interoperability of HLA can be expanded into other domains besides the distributed simulation domain.
