The flag and icons are intended to represent everyone who is seeking or pursuing relationships based on ownership or possession: that is, Master/slave or Dominance/submission relationships where some or all of the rights associated with property ownership are held by the master, mistress, owner or dominant.
There are more pages about the Flag and the Icons, including image files you can use. When used to represent relationships of ownership or possession these designs and image files may be reproduced freely for commercial or non-commercial purposes, without prior permission.

The O&P Wiki contains articles about O&P and related D/s, M/s, and BDSM topics.
