基于元构件模型的GIS构件自动组装

GIS Component Automatic Composition Based on Meta-component Model

摘要: 研究了在GIS领域背景下基于元构件模型的GIS构件自动组装,其核心思想是在GIS构件的元构件模型中描述与GIS领域相关的语义信息及构件的构造信息。组装时,以用户输入的任务需求为依据,根据元构件模型中描述的GIS构件语义信息在GIS构件库中查找与任务匹配的GIS构件,根据元构件模型中描述的GIS构件的接口信息、构件间的连接信息及构件规则信息等实现GIS构件运行时的自动组装。

Abstract: An meta-component modal is established and an approach to composit GIS components oriented user's tasks is proposed based on their meta-component modal which not only describes semantic information of a GIS component,but also the synthetic information,finally a prototype is implemented.
