This page provides a reference of the **ObjectTypeInfo** properties that you can use to [set the type information for custom module classes](https://docs.kentico.com/13/custom-development/creating-custom-modules/setting-the-type-information-for-module-classes.md).
The _ObjectTypeInfo_ class has the following types of properties:
> **Info:** The reference lists the **ObjectTypeInfo** members that are intended for public use. The class also contains other members, which are used internally or handled automatically by the system. We do not recommend working with any of the undocumented members.
## Constructor
The following properties are always set through the constructor parameters when creating new _ObjectTypeInfo_ instances:
| Property | Type | Description |
| ----------------- | --------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| BinaryColumn | string | The name of the class field that stores binary data for objects. Can be _null_. |
| CodeNameColumn | string | The name of the class field that stores the unique text identifiers of objects.
Can be _null_ for classes without a dedicated code name column. |
| DisplayNameColumn | string | The name of the class field that stores the visible names of objects (names used in the administration interface or on the live site). Can be _null_. |
| GuidColumn | string | The name of the class field that stores the [GUID identifiers](http://en.wikipedia.org/wiki/Globally_unique_identifier) of objects. Can be _null_. |
| IDColumn | string | The name of the class field that stores the IDs of objects (i.e. the primary key column).
Can be _null_ in rare cases (for example binding classes without an identity column). |
| ObjectClassName | string | **Required** for all classes.
The code name assigned to the class in the Xperience administration interface. Identifies the class's definition in the database. |
| ObjectType | string | **Required** for all classes.
Serves as the primary identifier string for the class. Use the object type name to select classes in the API, user interface components ([UniGrid](https://docs.kentico.com/13/custom-development/extending-the-administration-interface/ui-controls/unigrid.md), [UniSelector](https://docs.kentico.com/13/custom-development/extending-the-administration-interface/ui-controls/uniselector.md)), [REST calls](https://docs.kentico.com/13/integrating-3rd-party-systems/xperience-rest-service/getting-data-using-rest.md), etc.
The recommended place to define the object type name value is within the code of the _Info_ class, in the _OBJECT\_TYPE_ constant. |
| ParentIDColumn | string | The name of the class field that stores the IDs of parent objects. Set to _null_ for classes without a parent class.
See [Setting parent-child relationships for classes](https://docs.kentico.com/13/custom-development/creating-custom-modules/setting-the-type-information-for-module-classes/setting-parent-child-relationships-for-classes.md) to learn more. |
| ParentObjectType | string | The _object type name_ of the class's parent (as defined in the type information of the parent class). Set to _null_ for classes without a parent class. |
| ProviderType | [Type](https://docs.microsoft.com/en-us/dotnet/api/system.type) | **Required** for all classes.
The type of the class's _InfoProvider_ class. For example: _typeof(UserInfoProvider)_ |
| SiteIDColumn | string | The name of the class field that stores site IDs for site-related objects. Can be _null_.
Only use site ID columns if you do not have a separate [binding class](https://docs.kentico.com/13/custom-development/creating-custom-modules/creating-custom-binding-classes.md) for the site relationship. |
| TimeStampColumn | string | The name of the class field that stores the last modification date for objects. Can be _null_. |

You can also set the path column separately for paths built out of objects names or object IDs through the **ObjectNamePathColumn** and **ObjectIDPathColumn** properties respectively. |
| OrderColumn | string | The name of the class field that stores the order of objects (for classes that have a defined order for objects). Allows automatic actions for changing object order on listing pages (i.e. in [UniGrid](https://docs.kentico.com/13/custom-development/extending-the-administration-interface/ui-controls/unigrid.md) components). |
| ResourceIDColumn | string | The name of the class field that stores references (IDs) pointing to a module in Xperience. Intended for classes whose objects have a relationship with a specific module. |
| SizeColumn | string | Intended for classes that store binary data. Sets the name of the class field that stores the size of the binary data. |
| VersionGUIDColumn | string | The name of the class field that stores the GUID identifiers for individual [versions of objects](https://docs.kentico.com/13/configuring-xperience/working-with-object-versioning.md). |
