The file format transformation of STEP and XML was realized depending on the established mapping mechanism from Express to Schema. 研究了建立Express到Schema的映射关系,实现了STEP和XML两种文件格式之间的转换;
Accurate and uniform description of manufacturing resource information is the key in Manufacturing Grid ( MG ) system. The file format transformation of STEP and XML was realized depending on the established mapping mechanism from Express to Schema. 正确而统一的制造资源信息描述是制造网格系统实现的关键.研究了建立Express到Schema的映射关系,实现了STEP和XML两种文件格式之间的转换;
The software is developed, which can translate an EXPRESS schema into the SQL statements which generate a relational databases schema for storing STEP data. The software will greatly improve the efficiency of implementation of the STEP standard. 基于上述映射规则,开发了一个能够实现EXPRESS到SQL自动转换的软件&EXPRESSSQL转换器,极大地提高了STEP标准应用效率。
