Introduction
Analysis of the core framework of the standard
| Quality dimensions | Key points for detection | Technical indicators |
|---|---|---|
| Validity | System compatibility | No data corruption/abnormal error |
| Completeness | Required content verification | Metadata/Copyright record/Instructions for use |
| Normativity | Format and presentation | 6 formats including PDF/HTML/CEBX |
| Accuracy | Content accuracy | Error rate ≤ 0.0025% |
Detailed explanation of key technical requirements
1. Text content specifications
Different stages of education must meet differentiated display requirements:
- Primary school grades 1-2: Font size ≥ 16P, line spacing ≥ 5mm
- Junior high school stage: Font size ≥ 12P, line spacing ≥ 3mm
- Classroom large-screen display: Minimum font size 21P
2. Multimedia detection standards
Typical case: Video content detection must meet the following requirements at the same time:
- Resolution ≥ 1280×720 pixels
- Frame rate ≥ 25fps
- Duration of a single segment in primary school ≤ 20 minutes
Implementation suggestions
Quality control in the development phase
It is recommended to establish a three-level quality inspection mechanism:
| Detection level | Detection content | Tool recommendations |
|---|---|---|
| Material level | Single file format verification | PDF parser/FFmpeg |
| Component level | Content relevance check | XPath verification tool |
| System level | Cross-platform compatibility test | Virtual machine cluster |
Avoidance of common problems
- Font embedding: Ensure that PDF files fully embed font subsets
- Metadata specifications: Strictly follow the 38 required fields of GB/T41469
- Error control: Establish a pre-release proofreading process, focusing on checking:
- Political statements
- Accuracy of scientific concepts
- Cross-media citation relationships
