GB/T 37688-2019 in English

National Standard of the People's Republic of China GB/T 37688—2019 Interpretation: Measurement of Interoperability of Streaming Documents

I. Introduction

With the rapid development of information technology, streaming documents are increasingly used in the fields of office and publishing. However, the interoperability issues between different document formats have gradually become prominent, seriously affecting the efficiency of information sharing and collaboration. GB/T 37688—2019 standard came into being, aiming to provide a scientific measurement method and framework for the interoperability of streaming documents. This standard applies to the activities of stream document writers and users in document creation, editing, modification and review during the document life cycle.

II. Background and significance of the standard

This standard was proposed and coordinated by the National Technical Committee for Information Technology Standardization, and the main drafting units include Beijing Information Science and Technology University, China Electronics Technology Standardization Institute and other authoritative institutions. The formulation of the standard is based on the following backgrounds:

• Coexistence of multiple document formats: There are currently a variety of streaming document format standards, such as UOF, OOXML, ODF, etc., and the interoperability issues between these formats need to be resolved urgently.
• Complex and diverse functional points: The functional point definitions of different formats are not exactly the same, resulting in information loss or deformation during the conversion process.
• Diversified user needs: Users need to switch freely between different document formats while keeping the content and style intact and consistent.

III. Interoperability classification and measurement model

Classification dimension	Document format interoperability	Document instance interoperability	Interoperability level
Function point mapping capability	Full mapping capability of function points between formats	Compatibility of instance function points in target format	Good, average, poor
Conversion complexity	Difficulty of function point conversion based on format characteristics	Conversion feasibility based on instance function points	-

V. Interoperability Measurement Methods and Application Recommendations

5.1 Application Grading Assessment

According to the interoperability level, users can adopt different strategies:

• Good interoperability: Supports complex function point conversion, recommended.
• General interoperability: Some functions are limited, and careful evaluation is required.
• Poor interoperability: Key functions cannot be retained, and it is recommended to avoid use.

5.2 Implementation Recommendations

To improve document interoperability, the following measures are recommended:

• Prefer formats with high compatibility: such as open standards such as ODF.
• Optimize function point design: avoid using function points with low DT values.
• Regularly evaluate interoperability: ensure the overall compatibility of the document set.

VI. Case Analysis and References

Appendix A shows in detail the interoperability application cases of OOXML and UOF formats. The effectiveness and practicality of the model are verified through function point comparison and DT value calculation. As shown in Figure A.1, the choice of the instance document on the function point paragraph border and sentence border has a significant impact on the interoperability results.
