application/json as described in [RFC8259]


Security considerations:
This media type has all of the same security
considerations of application/json as described in [RFC8259].

Depending on the operational context of the device or software being described by the SBOM there may be additional security requirements. These may include but are not limited to, encryption at rest, encryption in transit, and restrictions on the transmission of the SBOM to 3rd parties. These additional requirements are considered out of scope for the specification. They will typically be enforced by contract or copyright terms.

It will also be used by tools that consume SBOMs for software
supply chain, component, supplier, license, and vulnerability
analysis.
