Workflows > Assign a Fingerprint > Two Different Approaches to Assign a Fingerprint

There are two different approaches on how to assign a fingerprint.

The following table shows a comparison between the two approaches:

Structure First	Evidence First
In this scenario, the first step is to set up a structure of publishers, products, and versions.	In this scenario, the fingerprints is always assigned first.
Try to have the most complete picture of the catalog without adding evidence.	If a matching product/publisher/version is available use it. Otherwise, use the wizard to create a new one.
Once this is initially ready, go to the fingerprints and assign them to already existing versions.	Later revisit the newly created structures and extend them by some non-required data (links, classifications, meta-data, etc.)

Both scenarios have their pros and cons and both are supported by RayVentory Catalog.
