The Rules Wizard periodically
queries the Metadata Service
for a list of metadata records
that are set to expire. The
Metadata Service only returns
assets that are set to expire and
are not flagged as being on
hold.
For each metadata
record set to expire the
Rules Wizard queries
the ASK for related
asset components (e.g.
hi-res, storyboard,
thumbnail, etc.).
For each asset component the Rules
Wizard communicates the appropriate
MDI to initiate a delete. The MDI
communicates to the appropriate hi-res
system (Profile XP, News NAS, etc.) to
complete the delete.
Purge removes all associated components
of an asset. The metadata record is the
last component deleted, so that if for any
reason any component fails to delete, its
record is still intact and the component is
visible to the NewsBrowse application.
