Officevision/2 Property Model

       This article discusses the OfficeVision/2 (OV/2) property

      OV/2 has an object-oriented user interface.  As such, users do
not focus on applications, but on their data.  In OV/2, users open
data objects, not applications.  In fact, there are no recognizable
applications, i.e., no application icons, shipped with OV/2.  For
example, there is no editor icon that represents a word processor.

      The notion of application is common in today's office systems.
Users run applications and load, or open, data files into those
applications. Some applications permit customization or stylization
via application profiles. (Application profiles are akin to style
sheets popularized by word processing applications.)  Without the
notion of application, it is difficult to map the concept of profiles
and style sheets into an object-oriented world.

      Also, most file systems today have a notion of file attributes
that describe statistics like the date and time the file was created
and last modified, who the owner is, and what the size is.  Some of
these attributes may also be user-settable, e.g., the file's security
level and a short description.  In an object-oriented world, the
files are viewed as objects and their attributes as object
properties; this is a natural mapping.

      OV/2 user interface designers introduced a "property model"
that unified application options and file attributes. The documented
model formalizes the concept of properties for all objects,...
