Suppose we create a card named Joe's Coffee+hours. It's name contains a "+"!
When we have a card with this name, we know that we have two other cards: one named Joe's Coffee, and another named hours. If you create a compound card and the parts don't already exist, Wagn creates them automatically.
Remember that Wagn names are unique. There can only ever be one card with a given name. For example, there can only be one Joe's Coffee card on any Wagn website.
If we were to create Joe's Coffee+location and Joe's Coffee+menu, they would both share the same left part (Joe's Coffee) with our original card, Joe's Coffee+hours. By the same token, if we created a card named The Bumpy Grind+hours, it would share its right part (hours).
This means that we can use naming patterns alone to start creating networks of information. With the above examples, Joe's Coffee is "plussed" to three other cards, and hours is "plussed" to two.
By following naming patterns like these, we can begin to organize card information in highly flexible ways.
