基于OCL的网格服务信息描述模型

his paper proposes a description model of grid service information using OCL. The concept of representation model for grid service is introduced, and also the structure of management model for grid service information and its constraint are explained. The model creates the association and index among the features of grid service information, which provides a basis for efficiently retrieving the services based on their features. Additionally, the OCL formalized description of the model can provide an accurate semantic support for such model. As a result, it can guarantee the consistency and the validity for the model. The theoretical analysis and the experimental results prove that this model is reasonable and valid.
