SPACE is a standard with data elements
and controlled vocabularies defining the working
components. The idea for the structure comes from
the fact that the XML schema is made from the
data elements which do not change as frequently
nor are updated as often as specific coding for
business functions. For example if a publication
offered a new size or position, then the change
would be made in the vocabulary section of the
standard not the data elements.
Put another way, The schema is made up of data
elements. Data elements are analogous to the floors
of a building. If a change is made to the building
it is rare to change the number of floors. The
layout of offices on any one floor is often changed
and can be changed without changing the building
structure. The vocabularies are the equivalent
of changing the layout of a floor plan.
The following list is a alphabetical listing
of data elements. The name of the element is displayed
in bold type. A description of the element follows
with a identification of the related data elements.
The related data elements are listed as children
or related subordinate elements.
