Infinite Filing Cabinet for CAPS™ — presented at the ACCU Spring Conference, April 2003, UK.

The workhorse of the CAPS™" system is a server module called the Infinite Filing Cabinet (IFC"). Using a regular RDBMS as backend, the IFC provides persistent storage for Python objects. These objects can be stored, retrieved and searched for. In addition, notification of object creation and modification can be requested. More complex actions can also be performed when objects transit specified states at optionally specified times. The IFC does not support the deletion of data; this is performed by deprecation. It is therefore possible to access any object in any of its prior forms.
