Once an application has been initialized, the PIA server "knows about it" and
can recognize various shorthand forms of addressing the application and its
constituent parts. For example, consider the agent History:
- /Agents/History/
- The History application's ``home directory''.
- /~History/
- An alias for the History application's home directory. The
aliasing is performed by means of an ``agent'' contained in
History's configuration file (
_subsite.xcf
). Note that
the alias does not have to have the same name as the
application's directory: the alias for
/Agents/SimpleCalendar
is ~Calendar
.
- /~History/-
- A generic listing of History's home directory. This will work
with any directory, not just agent homes, although it can be
hidden by the site designer. For example,
/-
gives a generic listing of the PIA's home
directory.
- /~History/DATA/
- Usually the application's data directory, if it has one. This is just
a convention that is not universal: for example, the SimpleCalendar
application keeps calendar events in a collection of subdirectories
with four-digit names like
/~Calendar/1999/
.
- /~History/DATA/-
- A generic listing of the data directory.
