《GB/T 36097-2018信息技术 学习、教育和培训 虚拟实验构件元数据》由TC28（全国信息技术标准化技术委员会）归口，TC28SC36（全国信息技术标准化技术委员会教育技术分会）执行，主管部门为国家标准化管理委员会。
Introduction
Analysis of Core Metadata Structure
| Element Category | Required Elements | Optional Elements | Extended Elements |
|---|---|---|---|
| Number of Components | 6 Categories (General/Lifetime, etc.) | 2 Categories (Classification/Function) | 4 Categories (Computers/Electronics, etc.) |
| Constraint Level | M (Mandatory) | O (Optional) | Extensible |
| Typical Applications | Basic Attribute Description | Enhanced retrieval | Discipline-specific attributes |
Key technical features
Multi-language processing mechanism: Adopts the GB/T 13000 character set standard, supports multi-language descriptions of virtual experimental components, and requires Chinese characters to support at least the mandatory part of GB18030.
Structured encoding: Adopts a 5-bit ID hierarchical identification system (such as 11100 is a sub-element of 11000), allowing dynamic adjustment of element order while maintaining structural integrity.
Special elements in the field of education
- Interaction level grading: 5 levels of quantitative standards from "very low" to "very high"
- Applicable age algorithm: Support the "minimum age-maximum age" format (such as "7-9")
- Subject mapping: Reference GB/T 13745 subject classification code
Implementation suggestions
- Prioritize the implementation of 6 types of required elements to ensure the basic interoperability of the virtual experiment system
- Subject extension elements are recommended to be implemented as needed, such as the "transistor polarity" attribute in the field of electronics and electrical engineering
- The date and time format strictly follows GB/T7408, and the duration accuracy must reach the second level
Technical evolution analysis
This standard is different from GB/T 21365-2008 Learning Object Metadata remains compatible, and new technical attributes (such as pin definition and power type) specific to Experimental Components are added, reflecting the development trend of educational informatization from content digitization to experimental simulation.
