Introduction
Standard Overview and Technological Evolution
GB/T 39073-2020 is a basic standard in the field of brand evaluation. Its formulation refers to a number of national standards such as GB/T 26816-2011, reflecting the technological evolution of my country's brand evaluation system from qualitative analysis to data-driven evaluation. The standard has established for the first time a metadata model consisting of seven core modules:
| Module Name | English Logo | Required Attributes | Data Example |
|---|---|---|---|
| Evaluation Subject | EvaluationSubject | M | China Brand Building Promotion Association |
| Evaluation Object | EvaluationObject | M | HaierBrand |
| Brand Value | brandValue | M | 1500 (billion yuan) |
Analysis of Core Metadata Technology
4.1 Metadata Attribute Definition
The standard adopts 8 major attributes to accurately define metadata:
- Chinese name: such as “brand strength”
- Value range constraint: Numerical fields are limited to the range of 0-1000
- Number of occurrences: Evaluation expert information can be recorded repeatedly (N times)
5.2 UML model design
Three major association relationships are realized through UML class diagrams:
evaluation object and evaluation indicator form a 1:N aggregation relationship. For example, a certain car brand can be associated with multiple indicators such as “quality and safety” and “market share”.
Implementation Suggestions
System Development Adaptation
It is recommended to use the XML Schema provided in Appendix A of the standard to define the data exchange format to ensure:
- Required field completeness rate ≥ 98%
- Date format strictly follows YYYY-MM-DD
- Brand value unit is unified as "100 million yuan"
Extended application scenarios
When it is necessary to add new dimensions such as "social media influence", the following should be followed:
| Extended type | Compliance requirements | Example |
|---|---|---|
| Add new elements | Keep the original data type | add number of fans (numeric) |
| Value range extension | Create new code table | Add KOL classification code |
