GitHub - sigmf/SigMF: The Signal Metadata Format Specification
By providing a standard way to describe data recordings, SigMF facilitates the sharing of data, prevents the "bitrot" of datasets wherein details of the capture are lost over time, and makes it possible for different tools to operate on the same dataset, thus enabling data portability between tools and workflows.Mon Oct 23 10:22:59 2023 - permalink -
Implementations of the the standard are available for Python, C++ and GNU Radio.- https://github.com/sigmf/SigMF
