An object persistence framework is essentially a library of pre-written code that takes care of the details of persisting, or permanently storing an object. There are already some OPFs available for the Delphi Win32 versions, for example the open source tiOPF which has an active community.
Another project has now joined this group, hcOPF, developed by Larry Hengen.

The project is hosted on SourceForge at http://sourceforge.net/projects/larryhengensopf/.
