# Relations

The relations tab is designed to allow you to include links and references to additional information about the cultural object and/or your 3D project. The form comprises of two elements:

* **links** - use this element to provide URLs.  These will become active links to information that is available online, so take care to include the complete http link.
* **other (bibliography)** - you can use this element to provide conventional bibliographic references as free text.

{% hint style="info" %}
You can add as many links and bibliographic references as needed.  Simply click on the green + to repeat the element.
{% endhint %}

![](/files/-LvBr4HDqv5cjhTdz5Or)

When you have completed adding links and references, **save** the changes before moving to the next tab.
