Ah, but there are actually different types of SBOMs, that describe the software in different parts of its lifecycle. It's a completely different outcome to record the software when looking at its source, at what is being distributed, or at what is being installed, for example.
At some point we realized that we were talking across each other, since everyone was using "SBOM" to describe different contents and use cases.
The consensus was expressed around 3 years ago, and published in https://www.cisa.gov/sites/default/files/2023-04/sbom-types-...
I haven't had a chance to read that, but do you think it would be impractical to have the different types of SBOMs declared in a standardized format? My impression is that no matter what, authenticity needs to be established, so it will always fall under "cryptographic verification of information about software", it is the standardization of that which I have an issue with.
