I recently published two Standards for Professional Photo Organizers and Photo Managers.
Each Standard has 10 Best Practices that, when followed, ensure the Standards can be achieved.
The Best Practices focus on typical tasks and how applications commonly used for photo organizing can handle those tasks. The information is on extensive testing.
While the applications were not rated, Directory Opus was by far the most recommended application.
