At present, several feature meta-models have been come up with. However, they can’t meet the requirements of dynamic Internet
environment or software reuse. This paper proposes a feature meta-model based on ontology as well as its formal description.
Meanwhile, FTM (Flexible Transaction Model) mechanism is considered. In particular, it is adaptable to the changes in dynamic
environment and can meet the requirement of software reuse. Finally, an example is given to verify this model.
