In workflow applications we often need to save Fully Qualified names in Readers/Authors/Names type fields in order to reduce name ambiguities e.g. “Joe User/dev/demo” or “Joe User/adm/demo” however for display purposes people like to have “Joe User” only instead of complete fully qualified name so normally developers create 2 fields 1 for display purpose and other for application logic (workflow, security etc)
There should an option on Names type fields properties box (Readers/Authors/Names) how to display the contents of that fields e.g. following options could be there:
a. Common Name only
b. Abbreviated Name
c. Cannonical Name
However actual value either could be saved as in Canonical Format or Abbreviated Format. Using this feature a single field could serve both purposes. This feature should also entertain multi values.
