> I long for a logging format in the specification. The requirements for a logging format: Self-describing – We want a way to persist data without needed external links to message definitions.

[https://dev.px4.io/v1.9.0/en/log/ulog\_file\_format.html](https://dev.px4.io/v1.9.0/en/log/ulog_file_format.html) If not, is there a better standards to adopt?

Would you be interested in collaborating with us to enable this feature in PyUAVCAN, and then, by extension, in Yukon?
