The root table for the acs object heirarchy. It all starts here folks.

object_id

object_type
varchar
context_id
int4
The context_id column points to an object that provides a context for this object. Often this will reflect an observed hierarchy in a site, for example a bboard message would probably list a bboard topic as it's context, and a bboard topic might list a sub-site as it's context. Whenever we ask a question of the form "can user X perform action Y on object Z", the acs security model will defer to an object's context if there is no information about user X's permission to perform action Y on object Z.
security_inherit_p
bool
creation_user
int4
Who created the object; may be null since objects can be created by automated processes
