Very often you want to re-use an existing piece of information. Examples are:
- One-to-One re-use: you already have a person on one page, and want to use the same person on another page
- Use in list and again standalone: you already have a person to one page, and now want to add him to a list of people manually
- Re-use with different layout: you already have a person on one page - showing the face and name, and now you want to show the same person on a google map
This is very easy in 2sxc, as you can always choose to re-use an existing item instead of adding another.
So you have two options
- re-use item which are the same item
- re-use a copy of an item
