CI attributes Attributes apply to all of the CIs in a classification. To change attributes for a CI, you must extend the table and create a new classification for that CI. The position of a CI in the classification hierarchy is determined by the attributes it shares with the CIs below it. Each time a CI has a single different attribute from its parent, the classification hierarchy branches. For example, servers have different attributes from computers, which includes workstations and laptops. Linux servers and UNIX servers have different attributes from the parent server classification and from each other, so they occupy separate branches in the hierarchy.
