Creation Date and Time of SBOM Document

Generation Context
In an SBOM Document, element values specifying the timing and method of its creation SHOULD be included, as these details are crucial for vulnerability management. Therefore, including the generation context such as SBOM Types defined by CISA in the document can enhance its overall quality. However, since a standardized element for generation context may not exist, harmonizing their usage across the supply chain is essential.

Software Package information

[Comments / Suggested Changes]
If a toolchain that uses multiple tools, might be considered internal/confidential. This information does not bear any quality statement - just delegation of responsibility. IMHO an SBOM should be warranted by the author. Nonetheless, purely internal SBOMs can carry this information for traceability.

The purpose of this information is not to disclose internal toolchains or delegate responsibility.
The SBOM producer remains responsible for the content of the SBOM. Rather, generation context provides important information about the scope, expected completeness, and limitations of the SBOM by indicating when in the software lifecycle the SBOM was generated.
