| `object_version.obj_id.type` | `int32` | The object type ID, for example 0 for documents. In a lookup value, the value list ID (for a lookup to objects, the object type ID). |
| `object_version.obj_id.item_id` | [`ItemID`](https://developer.m-files.com/APIs/gRPC-API/Reference/Messages/MFiles.ItemID/index.md) | The ID of the object within its type, in `item_id.internal_id`. |
| `object_version.version` | [`ObjVerVersion`](https://developer.m-files.com/APIs/gRPC-API/Reference/Messages/MFiles.ObjVerVersion/index.md) | The version. Usually `OBJ_VER_VERSION_TYPE_SPECIFIC` with `internal_version`. |
| `object_version.version.type` | [`ObjVerVersionType`](https://developer.m-files.com/APIs/gRPC-API/Reference/Enums/MFiles.ObjVerVersionType/index.md) | What `internal_version` means. `OBJ_VER_VERSION_TYPE_SPECIFIC` for a version number. Values: `OBJ_VER_VERSION_TYPE_UNINITIALIZED` (0), `OBJ_VER_VERSION_TYPE_LATEST` (1), `OBJ_VER_VERSION_TYPE_ANY` (2), `OBJ_VER_VERSION_TYPE_ALL` (3), `OBJ_VER_VERSION_TYPE_SPECIFIC` (4), `OBJ_VER_VERSION_TYPE_VALUE_LIST_ITEM` (6), `OBJ_VER_VERSION_TYPE_OBJECT_LEVEL_REFERENCE` (7). |
| `object_version.version.internal_version` | `int32` | The version number, starting from 1, when `type` is `OBJ_VER_VERSION_TYPE_SPECIFIC`. The server returns -1 with `OBJ_VER_VERSION_TYPE_LATEST`. |
| `object_version.version.external_repository_version` | `string` | Used only for objects in external repositories. Leave empty. |
| `object_version.version.external_repository_sort_key` | `int64` | Used only for objects in external repositories. Leave 0. |
| `allow_modifying_checked_in_object` | `bool` | Whether to allow modifying a checked-in object (automatic checkout and checkin). |
| `allow_missing_required_properties` | `bool` | Whether to allow missing required properties on the set. |
| `property_values[]` | repeated [`PropertyValueWithMetadata`](https://developer.m-files.com/APIs/gRPC-API/Reference/Messages/MFiles.PropertyValueWithMetadata/index.md) | The property values with metadata to set. |
| `property_values[].property_def` | `int32` | Property definition ID. |
| `property_values[].value` | [`TypedValueWithMetadata`](https://developer.m-files.com/APIs/gRPC-API/Reference/Messages/MFiles.TypedValueWithMetadata/index.md) | The value of the property. |
| `property_values[].value.type` | [`Datatype`](https://developer.m-files.com/APIs/gRPC-API/Reference/Enums/MFiles.Datatype/index.md) | Data type. Note. Name of the property can't be isNull because name collision with Objective-C reserved name. |
| `property_values[].value.is_null_value` | `bool` | Is the value unset. |
| `property_values[].value.data` | [`TypedValueUnionWithMetadata`](https://developer.m-files.com/APIs/gRPC-API/Reference/Messages/MFiles.TypedValueUnionWithMetadata/index.md) | The value data as a union, if set. |
| `property_values[].value.value_metadata` | [`TypedValueMetadata`](https://developer.m-files.com/APIs/gRPC-API/Reference/Messages/MFiles.TypedValueMetadata/index.md) | The metadata about the typed value. If the value is a Lookup or MSLookup, this data will be in that struct. |
| `attributed_to_user_id` | `int32` | Built-in agent user ID to attribute the change to, or 0 for no attribution. |
