There are many history MBD models in aviation enterprises

which have great reuse value. It is the key problem to construct normalized model storage data structure in model reuse

we researched on the organizational form of MBD model data

used ontology technology as knowledge expression form of model type division and attribute information

designed ontology data structure including both geometry and non-geometry information. Based on this kind of data form

We transform history model data into structural ontology knowledge base and verify technical feasibility by retrieval of model key information

make preparation for magnanimity model data reuse.
