Plugin Repo Factory and Registry

To be available for installation in the Aragon OSx framework, a PluginRepo must be created for each plugin. The PluginRepo creation process is handled by the PluginRepoFactory contract who creates the PluginRepo instance for each plugin to hold all plugin versions and the PluginRepoRegistry contract who registers the Plugin in the framework for DAOs to install.

Plugin Repo Factory

The PluginRepoFactory is the contract in charge of creating the first version of a plugin. It does this through the createPluginRepoWithFirstVersion function which creates a PluginRepo instance for the plugin with the first release and first build (v1.1).

/// @notice Creates and registers a `PluginRepo` with an ENS subdomain and publishes an initial version `1.1`.
/// @param _subdomain The plugin repository subdomain.
/// @param _pluginSetup The plugin factory contract associated with the plugin version.
/// @param _maintainer The plugin maintainer address.
/// @param _releaseMetadata The release metadata URI.
/// @param _buildMetadata The build metadata URI.
/// @dev After the creation of the `PluginRepo` and release of the first version by the factory, ownership is transferred to the `_maintainer` address.
function createPluginRepoWithFirstVersion(
  string calldata _subdomain,
  address _pluginSetup,
  address _maintainer,
  bytes memory _releaseMetadata,
  bytes memory _buildMetadata
) external returns (PluginRepo pluginRepo);

It also registers the plugin in the Aragon OSx PluginRepoRegistry contract with an ENS subdomain under the plugin.dao.eth domain managed by Aragon.

Additional to the information required by the createVersion function discussed earlier, it receives:

  • A valid ENS _subdomain unique name composed of letters from a-z, all in lower caps, separated by a -. For ex: token-voting-plugin.

  • The address of the plugin repo maintainer who ends up having the ROOT_PERMISSION_ID, MAINTAINER_PERMISSION_ID, and UPGRADE_REPO_PERMISSION_ID permissions. These permissions enable the maintainer to call the internal PermissionManager, the createVersion and updateReleaseMetadata functions as well as upgrading the plugin contract.

Plugin Repo Registry

The PluginRepoRegistry contract is the central contract listing all the plugins managed through the Aragon OSx protocol. The PluginRepoFactory calls on the PluginRepoRegistry to register the plugin in the Aragon OSx protocol.

/// @notice Registers a plugin repository with a subdomain and address.
/// @param subdomain The subdomain of the PluginRepo.
/// @param pluginRepo The address of the PluginRepo contract.
function registerPluginRepo(
string calldata subdomain,
address pluginRepo
) external auth(REGISTER_PLUGIN_REPO_PERMISSION_ID) {
  ...
}
