摘要
美军靶场在数据资源建设过程中,针对不同领域建立了大量的元数据,发挥了应有作用。但这些不同来源的元数据存在范围广、格式杂、含义乱等问题。美军靶场指挥官协会(RCC)与基于知识的系统(KBSI)公司合作,研究形成统一的试验鉴定元数据及其标准化方法;在此基础上,为实现了元数据全生命周期的高效管理,充分发挥元数据价值,建立了试验元数据集市项目。
In the process of data resource construction, US army gains a lot of metadata and it has playded a role in different field. But the metadata has some existing problems, such as wide range, more formats, confused meaning and so on. Unified test identification metadata and its standardized methods are studied by RCC and KBSI company. On this basis, test metadata mart proiect is set up to manage the lifecyele of metadata efficiently and develop its value fully.
