Virtual Experiment Component Metadata Standard

The virtual experiment standard is an important and difficult work project of modern educational technique standards. To design and implement a graceful virtual experiment standard system, we defined a detailed virtual experiment standards framework based on the characters of China virtual experiment teaching. This paper introduces the structure of China virtual experiment standards framework, mainly illustrates the virtual experiment component metadata standard, and clarifies the data structure, mapping hierarchy and instance of component metadata. It also introduces a ¿virtual experiment technology standard support software platform¿ developed by the authors to provide strong support for the standardized development of virtual experiment resources in the future.
