I still find the labels confusing:

- That's the package, component. I also assume that the "maven" label/tag comes from the PURL as well.
- That's the PURL (or PURLs) of the package/component
- That's the "base PURL" of the package/component
- Those qualifiers come from the PURL, not from the package/component. As packages/components don't have that information.
