plus cards
Plus cards are cards with a "+" in the name.
The plus sign divides card names into left and right parts. Creating a plus card automatically creates a card for each of its parts (unless they already exist).
Examples
Suppose we create a card named Joe's Coffee+hours. It's name contains a "+", so it's a plus card!
When we see this plus card, we know that we have two other cards: one named Joe's Coffee, and another named hours. If they didn't already exist when we created the plus card, then they were created 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.
How To
There is very little "howto" involved in plus cards themselves. All you have to do is use a "+" in the name, and you're using plus cards.
In general, we do not recommend requiring casual site visitors to know anything about plus cards. Most visitors shouldn't have to know what a "card" is, much less a "plus card". A good Wagneer will create a site where this kind of background knowledge is completely unnecessary for casual users.
However, plus cards become powerful when you start using them in highly patterned ways. To do so, you will need to learn about contextual names and formatting.
Tips
More than one plus
- a plus card can have more than one "+". E.g. Joe's Coffee+menu+specials.
- in such cases, the left and the right side are separated by the rightmost plus. So in this case the left would be Joe's Coffee+menu and the right would be specials.
- so: left + right = whole
