| Abstract: | [中文摘要]：模型元数据是资源环境模型共享的重要信息,它有利于促进模型的高效利用.在面向对象的资源环境模型库管理系统中,模型的属性、方法、数据接口和元数据被封装为模型对象,模型元数据用于资源环境模型的辅助管理.通过建立资源环境模型元数据库,开发基于Web的资源环境模型元数据管理系统,使Internet上的一般用户也可以查询到已建立模型的信息,避免了模型的重复构建,促进了资源环境模型信息的共享.目前,模型元数据研究还需要解决以下两个主要问题：①制定资源环境模型元数据的国家标准;②建立面向对象资源环境模型表达的行业规范.
[英文摘要]： Model metadata are the important information in spatial model sharing, which would promote model utilization much more. In object-oriented model base management system, properties, method, data interface and metadata of model are encapsulated as model object. Model metadata are used to assist model management. In the experimentation of model metadata management, we build a model metadata database and develop a webbased model metadata management system. The common user of Internet can access model information that has been built by using the model management system. It could be avoided to repeatedly construct the same model. At present, researches on model metadata have to resolve two primal problems： ①developing the national standard of spatial model metadata; and ②establishing standards of object-oriented spatial model representation. |
