Comparative Study of Data Sharing Based on Network Collaborative Design

摘要

The technology of collaborative design based on network has fully strengthened the cooperation ability among enterprises. However, the problem of heterogeneous data sharing among Different design software has been a bottleneck in the development of collaborative design. STEP/XML element mapping method has achieved the conversion between two kinds of data through the establishment of mapping relationship between STEP and XML data language. Because the syntax of the two languages is not the same, it is difficult to ensure the implementation of the mapping. It is likely to cause some data loss in the conversion process. STEP standard update fast and the system is huge, which is hard to achieve comprehensive conversion. Based on the research, the integrated packaging method has been put up in this paper, which is based on CDATA STEP to encapsulate the XML data in XML. Through the comparative study, the integrated packaging method can achieve the integrity of the product model data conversion, which is conducive to the realization of network collaborative design.
