# setMetadataOf

Allows a project owner to set the project's metadata content for a particular domain namespace.

Only a project's owner or operator can set its metadata.

Applications can use the domain namespace as they wish.

Definition

```javascript
function setMetadataOf(uint256 _projectId, SNWProjectMetadata calldata _metadata)
  external
  override
  requirePermission(ownerOf(_projectId), _projectId, SNOWperations.SET_METADATA) { ... }

```

Arguments:

* \_projectId is the ID of the project whose metadata is being changed.
* \_metadata is the struct containing metadata content, and domain within which the metadata applies.

Through the requirePermission modifier, the function is only accessible by the project's owner, or from an operator that has been given the SNWOperations.SET\_METADATA permission by the project owner for the provided \_projectId.

The function overrides a function definition from the ISNWProjects interface. The function doesn't return anything.

Body

```javascript
// Store the project's new metadata content within the specified domain.
metadataContentOf[_projectId][_metadata.domain] = _metadata.content;

```

Internal references:

Emit a SetMetadataCid event with the relevant parameters.
