Physicalisch-Technische Bundesanstalt¶
While working at PTB I collaborated on multiple Open-Source projects, all of them related with the DCC (Digital Calibration Certificate) project.
Dcc-Json Toolkit¶
| Repository | Role | Release |
|---|---|---|
| GitLab (PTB) | Creator |  |
The goal of dcc-json-toolkit is to present a set of tools that will prevail to be used with any new XSD release.
By scanning the used schema version, what the package offers is:
- Caching locally any released dcc.xsd file, together with all its required imports.
- Validation of any DCC file, printing all the possible issues it has.
- Bidirectional conversion XML-JSON for DCC files.
DCC Quantities¶
| Repository | Role | Release |
|---|---|---|
| GitLab (PTB) | Owner |  |
dccQuantities is a project oriented to all developers or researchers that require to work with a DCC table.
The key features that the library provides are:
- DCC XML Parsing & Serialization: Allowing to read tables from XML files and to export any new created or modified data.
- Uncertainty & Unit Awareness: Ensure uncertainty propagation using
metas_unclib, as well as the correct unit propagation usingdsiUnits. - Object‑Oriented Arithmetic: Allowing any math operation among Quantities (table data).
D-SI Units¶
| Repository | Role | Release |
|---|---|---|
| GitLab (PTB) | Maintainer |  |
dsiUnits is a python library with the goal of working with digital SI units, focused on the rules stated at the BIPM brochure.
This defines the cases of:
- Initializing a unit base on a given raw string.
- Allow mathematical operation over the units to obtain a new unit.
- Allow SIRP and LaTex representation of any unit.
- Simplify any complex unit to the tree conformed by the SI base units.
Example DCCs¶
| Repository | Role | Tech |
|---|---|---|
| GitLab (PTB) | Creator |    |
One previous persistent issue was that the example/open-source DCCs were complicated to be found. The first goal of the project was to present an interface which would hold all DCCs with open-source license.
The best way to comprehend the status and behaviour of the database is to see the deployed GitLab-pages and interact with it:
