In order for Snoopy to display a friendly name for the attributes it views it looks in two places. First off it checks the labels database. If it can't find an entry there it uses BeOS's MIME database. If it still can't find one it will display the attribute as the on-disk name
First of all, start the Snoopy Preflet and select "Labels" from the menu on the left.
Labels View
Next, click inside the list view on the right and press the "Insert" key. You'll be presented with an input control.
Adding a label pair
Enter in the attribute name and press the "Tab" or "Enter" key. This is the ondisk name of the attribute. We'll use the example "META:nickname" which Person files use to store the Person's nickname
Editing the internal name
Now enter the label you wish Snoopy to use and press "Tab"/ "Enter". We'll use "Friendly Name"
Adding the label
You can edit a previous label set by clicking on the entry and pressing the "F2" key.
