Broadleaf Microservices supports the concept of a "marketplace" application - a commerce storefront where many "vendors" (think "third party sellers") can contribute their products for sale.
For such a setup, a Vendor
can be established in VendorServices.
This will cause various supporting entities to also be created for that vendor, such as a vendor-specific Catalog
and a relationship from that catalog to the marketplace Application
.
More details around catalog/application set-up in relation to marketplace behavior are documented in TenantServices.
