How to add an item type to the collection of dspace

We can add a new item type or edit the existing one in the list of item types in the dspace repository. 

Open the terminal and log in as a superuser

sudo su (Enter password)

Apply the below command to open the  XML file

sudo gedit /dspace/config/input-forms.xml 

See the following ".xml file", you will find that a number of such value pair lists of the item types are already pre-defined. 

Now copy the existing pair code of any item, replace the displayed value and stored value, and paste it between any predefined item types.

Save and close the file.

Restart Tomcat Server

sudo service tomcat start

Now You will see the item types on the submission page  that you have added in the space form

.
