.. glossary::

   class
      a definition of the properties and behaviour of a set of items

   classname
      the name of a class. It must start with a letter, end with a letter
      or "_", and only have alphanumerics and "_" in the middle.

   db (or hyperdb)
      a collection of items

   definitional class
      a class that exists to define a descrete set of values. For example
      status or priority.

   designator
      a combined class + itemid reference to any item in the
      hyperdb. E.g. issue26. Note that form values can include
      something that looks like a designator composed of a classname, a
      dash '-', and a number. E.g. file-1. These
      are used to create new instances of a class via the web interface.

   itemid
      a numeric reference to a particular item of one class

   item
      a collection of data that forms one entry in the hyperdb.

   property

      of item properties may be changed as needed - even after the 
      tracker has been initialised and used in production.

      the definition of all the classes that make up an tracker

   tracker
      the schema and hyperdb that forms one issue tracker
