Creating, Storing, and Classifying Metadata
Plato has extensive features for creating, storing, and classifying metadata. Metadata is data about your data. A note object, for instance, may have attributes such as topic, author, associated keywords, and date. A book object will have attributes such as author, title, publisher,and many more attributes depending on your use. These attributes are metadata.

Plato object classes and metadata are flexible and powerful. You can easily build ad-hoc databases that are quite complex. You may build classes that refer to each other (simulating relationality) and have validated fields, text macros, and fields that display the results of calculations performed on the contents of other fields. Since Plato automatically keeps indexes of each object class, keeping your data in closely defined object classes is a ready-made classification method at your disposal.
 
Screenshot: the Object Class List
The screenshot above is shows the object class list from a Plato class library. On the right hand side of the window is the object class list (top), with the class editing pane below it. From the editing pane you may:
  • name and describe object classes
  • assign them to categories (for better management of really large class lists)
  • assign actions (i.e., what happens when an instance of the object is clicked: open it as a folder, run it as a script, load a file into an external application, and the like)
  • assign field attributes
On the left hand of the pane is an object class filter tree (top) for organizing large numbers of object classes. Below this are two panes that show (respectively, top to bottom) the instances of the selected object class in the current database and all databases that contain instances of the selected object class.
