1. Asset Manager Queries.
The Asset Manager queries the
Metadata Service periodically
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
Asset Manager queries
the Resolver for related
asset components (e.g.
hi-res, storyboard,
thumbnail, etc.).
2. Delete Asset. For each asset
component the Asset Manager
communicates the appropriate MDI to
initiate a delete. The MDI communicates to
the appropriate hi-res system (K2, Media
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 Browse application.
