## 4 Conclusions  
This article emphasizes the importance of DCCs in the manufacturing industry for managing calibration information. It discusses the formulation and implementation plans for measurement standards and the advantages of using DCCs in response to the digital transformation of the measurement field. The proposed method involves using a hole plate to calibrate the CMM, and the experiment section explains the calibration process and measurement results using traditional standards for comparison. The coordinate system of the CMM, which comprises three linear axes, has a total of 21 geometric errors. The maximum difference in linear error deviations is smaller than \(-0.30\)\(\upmu\)m. The maximum difference in angle error deviations is smaller than \(-0.78\)\({}^{\prime\prime}\). The maximum difference in squareness error deviations is smaller than \(4.54\)\({}^{\prime\prime}\). To compare the hole plate measurement method, En-value is used which takes into account the difference in errors and expanded uncertainty. The maximum En-value is 0.85, which is less than 1. This paper also showcases the implementation of the DCC structure for hole plate measurements of a CMM, which converts the administrative information and measurement results into both XML and

PDF formats. The XML is primarily for machine-readability, while the PDF format is for human-readability. The use of DCCs is essential in ensuring accurate and traceable data during conversion and transmission processes. Additionally, the use of XML as a data exchange format offers several advantages, including easy information exchange between systems, structured and formatted data, and long-term data storage.
