For data governance and protection of information, if you
use classification labels or embed tags in MS Office and PDF documents
to include more information for audit and tracking purposes, you
can create a file property data pattern to match on the metadata
or attributes that are part of the custom or extended properties
in the file. Regardless whether you use an automated classification
mechanism, such as Titus, or whether require users to add a tag,
you can specify a name-value pair on which to match on a custom
or extended property embedded in the file.
