, create a product draft in the Publisher Portal. To access the Publisher Portal for UPM publishing:
  1. Enroll as a UPM publisher.
  2. Open the Asset Store, and select your user icon.
  3. Under Switch Organization, select your publisher organization.
Go to the UPM publishing Publisher Portal through the Cloud Dashboard:
  1. Go to the Cloud Dashboard.
  2. Select the Products tab. 1. In the search bar, enter Publisher Portal.
  3. Select Launch.
You can configure a product to handle single or multiple packages, as follows:
  • Single package: Only one package uploaded and linked to this product draft. New versions of the package continuously share the same package technical names. Ideal for a unified tool that supports a wide array of
    project settings

    .
  • Multiple packages: Various packages uploaded and linked to this product draft. The packages can be dependencies, dependents, or packages intended for different
    project

    ?

    settings or use cases. Ideal for support for multiple use cases, or different project compatibility settings, such as different Unity Editor versions.
You can start with a single package and add more later. When planning dependencies, use multiple packages if dependencies are only needed within one product. Dependent packages automatically install their dependencies. However, if a dependency is shared across multiple products, list it as its own separate product to avoid conflicts and project breaks. For more information about package dependencies, refer to Package dependency and resolution. The following table compares the properties of each product structure:

By default the uploaded Unity Editor version is checked for every package uploaded. Additionally, you can list all supported Unity versions that it's compatible with (major.minor). For

To create a product draft:
  1. Open the Publisher Portal.
  2. Go to the Products tab.
  3. Select Create product.
  4. Enter a product name.

Product and package naming

When a product has only one package, the product namespace and package namespace are the same, which follows the naming convention of 
com.publisher.product
. When a product has multiple packages, the product namespace follows the naming convention of 
com.publisher.product
(for example 
com.unity.assetstore
), and the package namespaces follow the naming convention of 
com.publisher.product.package1
(for example 
com.unity.assetstore.tools
). The following table describes the information each namespace identifies and its format in a complete UPM namespace:

Namespace type

Description

Example

Publisher namespaceThe publisher organization. This namespace uses the reverse domain name notation (reverse-DNS) naming convention. For example, the domain 
example.com
has the publisher namespace 
com.example
.
com.publisher
Product namespaceThe product. This namespace isn’t visible in the product's Asset Store listing.
.product
Package namespaceThe packages that the product contains. Set a package's namespace only for multi-package products.
  • product.package1
  • product.package2
[Package technical name]((https://docs.unity3d.com/6000.6/Documentation/Manual/upm-manifestPkg.html#required#required)The package technical name combines the publisher namespace, the product namespace, and for multi-package products, the package namespace. The Package's technical name must match the following:
  • Single package:
    • com.publisher.product
  • Multiple packages:
    • com.publisher.product.package1
    • com.publisher.product.package2
Note
The publisher namespace (
com.publisher
) is set during enrollment to the development membership program. If you want to know more about changing the namespace, contact Unity support.
