Content Type Hub in SharePoint .

Content Type Hub
Content Type Hub is a centralized location where we manage and publish content types to other web applications.

• Content Type Hub is actually a Site Collection.
  
  
• Content Type is published and subscribed using the Managed Metadata Service application.

Procedure

1. Follow the procedure below to create a content type hub. Open Central Administration then select Manage Web Applications > Create New Web Application. This will be our publishing application.
   
   
2. Create a new site collection under the new web application.
   
   
3. The site collection looks like the following.
   
   
4. Create a new content type under the site collection. Name it Travel Request.
   
   
5. Open Central Administration then select Manage Service Application > Choose Managed Metadata Service > Click Properties.
   
   
6. Enter the Content Type Hub URL as shown below.
   
   
7. Now choose the connection (sub item) of Managed Metadata Service.
   
   
8. Check the following options that ensure subscribing published content types.
   
   
   
9. Back to our Source Content Type. Choose the Content Type Settings > Manage Publishing for this Content Type.
