The Base Object Model (BOM) Primer: A Distilled Look at a Component Reuse Methodology for Simulation Interoperability

摘要

Base Object Models (BOMs) are a SISO approved form of Reference FOM. They promise to offer a componentized overlay to conventional HLA FOMs without breaking the HLA paradigm, and provide an appropriate mechanism for HLA reuse as identified in the recent MoA on HLA for DoD Simulations (circa Nov. 3, 2000). Moreover, BOM extensions have been recently proposed which might pave a migration path for HLA into exciting new add-in technologies and other simulation domains. This concept expansion includes building BOM sets from a clean sheet of paper, adding behavior to BOM infrastructures, and applying BOMs to support Advanced Distributed Learning (ADL) and Experiential Consumer Media. In the work-a-day HLA world, FOM development, maintenance and reconfiguration become increasingly important concerns for the HLA simulation community. Reuse is an important aspect of the HLA architecture, and the development of FOMs leveraging existing work helps to achieve simulation interoperability at a reasonable cost. The size of monolithic FOMs becomes unwieldy with continued growth, and the options in the construction of new FOMs become confusing. This paper proposes to capture and codify the emerging direction, approach, and methodology that is being developed and tracked by the BOM Study Group members.
