To get to the creation wizards, go to “create metadata” on your dashboard side panel, or the creation tool in the header bar and select “see all…”
Data element and data element concept wizards
Wizards help make metadata creation and reuse of metadata items easier. Using these wizards, you will be stepped through creating either a Data Element, and within the wizard you will create an object class, property, and value domain. Or, you can select to create a Data Element Concept, where you will create an object class and a property.

This is the form you will see when selecting to create a new data element

Single item creation wizards
These wizards are useful if you know you want to create just one item
This is the form you will see when selecting to create an object class
Because reuse is important, each wizard will search for the name of your item and give you results if there are any matching or similar to your item. If you would like to create a new item, select the box “None of the above meet my needs” and you will be able to continue to create the new item or items.
After creating the new item or items, you will be taken to a page to review the items before creation. If you are satisfied with these items and wish to create them, select "I've reviewed these items, and wish to create them."

Select "back" if you would like to edit the items before creating them, or select "next" to create the items.
After selecting "next" you will be taken to your newly created item page.
