<div class="refsect1title">Description</div>
<p>This function can detect and automatically fix most popular sorts of metadata corruption.</p>
</div>
<div class="refsect1">
<div class="refsect1title">Parameters</div>
<div class="refsect2">
<span class="refsect2title">audit_mode – </span>
(0|1|2 default 0) - 0 = read-only audit operation; 1 = audit and fix; 2 = audit, fix and garbage collection for all incomplete declarations
</div>
<div class="refsect2">
<span class="refsect2title">str_value – </span>
Default '' is to stop if the metadata graph contains marks that some storages are being edited.
'*' is to remove such marks.
Other values will be suggested by the error dump when appropriate.
</div>
<div class="refsect2">
<span class="refsect2title">graph_iri – </span>
Default is system metadata graph.
If specified then it should be a name of graph created by
<a href="fn_rdf_backup_metadata.html">DB.DBA.RDF_BACKUP_METADATA</a>.
It is possible to make the backup to a graph, test and maybe fix that backup and finally restore metadata from the fixed backup.
The disadvantage is that DB.DBA.RDF_AUDIT_METADATA() may detect and fix more errors on "active" metadata than on their backup.
The possible approach is to make backup, test and maybe fix it (after fix it can be tested one more time).
If the backup was successfully fixed then the DB.DBA.RDF_AUDIT_METADATA() is used to fix the "active" metadata, not the copy.
In any case, if one makes a backup to fix it then it's worth to make and keep another 'untouched' backup, just to stay on safe side.
