In the plugin site it would be great to show more metadata.

The following Metadata could be injected into the MANIFEST file:

• changelogUrl - Link to the custom changelog, e.g. in GitHub
• sourcesUrl - Url to plugin sources if they are being stored outside Jenkins 
• licenseType - License type. Enum for Common licenses, just to enhance the UI layout. Can be calculate from the license Field in POM
• licenseUrl - Link to the license file
• logoUrl - Just in case a plugin has a custom logo (like BO)

Manifest Entry Format: Plugin-FieldName

Once the info is in the Manifest, it can be processed by the plugin site backend
