An SBOM is a comprehensive inventory of all components and dependencies that make up a version of a software application, library, firmware etc. When such an artifact is registered in SBOM Central, it is assigned a Product identity, i.e. the combination of group (vendor) and name.
Example: An SBOM representing the application com.example/ep_cloud@1.3.4 gets the product identity com.example/ep_cloud. If the product already exists, the artifact will be assigned to it. If not, a new product is created.
In the CycloneDX standard the application is registered in the sections: metadata :: component :: group where the group often is a shortened, single name of the company or project that produced the component, or the source package or domain name & metadata :: component :: name the name of the component.
When opening the product show page, a table presents all artifacts and versions registered by the system.
