The Group IP Asset Registry is responsible for managing the registration and tracking of Group IP Assets, including the group members and reward pools.

The Group IP Asset Registry will maintain grouping relationship on-chain between the Group's IP Account and individual IP Accounts through a mapping:

```solidity GroupIPAssetRegistry.sol theme={null}
mapping(address groupIpId => EnumerableSet.AddressSet memberIpIds) groups;
```

### Notable Functions

```solidity GroupIPAssetRegistry.sol theme={null}
function registerGroup(address groupNft, uint256 groupNftId, address rewardPool) external onlyGroupingModule whenNotPaused returns (address groupId)
```

This function registers a new Group IPA on Story.

```solidity GroupIPAssetRegistry.sol theme={null}
function addGroupMember(address groupId, address[] calldata ipIds) external onlyGroupingModule whenNotPaused
```

Adds already registered IPAs to an existing Group IPA.

```solidity GroupIPAssetRegistry.sol theme={null}
function removeGroupMember(address groupId, address[] calldata ipIds) external onlyGroupingModule whenNotPaused
```

Removes registered IPAs from a Group IPA.
