PyDCC is an open-source project released under the MIT license, accelerating application development for processing Digital Calibration Certificates (DCC), according to the official DCC release [3]. This collaborative work was introduced by a talk given at the 2nd DCC conference [4]. Further, an introduction video [6] exists, looking briefly at the contents of a DCC and demonstrating PyDCC's essential features by implementing an example application from scratch. Note that to process DCC automatically, data within the DCC must follow particular format requirements defined by Good Practice [5].
Out of scope: PyDCC is not intended to modify or generate DCCs. PyDCC is a read-only library. For this purpose, other tools and libraries exist.
This software module is a joint initiative driven by the project GEMIMEG-II.
Maintainer: Andreas Tobola, Siemens AG
Contributors: The workflow was defined in the contribution guide. We appreciate any contributions.

The digital calibration certificate (DCC) is the machine-readable counterpart of the previous calibration certificate. The DCC was released by the Physikalisch-Technische Bundesanstalt (PTB) [1]. The DCC has a hierarchical structure comprising regulated areas whose information must meet specific requirements. The DCC exists in Extensible Markup Language (XML).
Python is a programming language widely used in science and cloud computing applications. This software library extends Python by capabilities of handling DCC, in particular, loading DCCs from XML-Files, and operating on regulated areas of the DCC. Regulated areas in DCC are (1) administrative data and (2) measurement results.
