Alias Identifiers

An AIM Workhub Object may have more than one Identifier:

A common example, as shown here, is when PDMS has been used on a project and it is desirable to identify an object with the PDMS form of the name as it appears on PDMS ISOs as well as the name appearing elsewhere in the project.

Identifiers can be added and deleted at any time but an Object must always have at least one. The last remaining Identifier cannot be deleted without deleting the Object itself.

When an object has more than one Identifier, one of them is designated as the ‘Preferred Identifier’ and is the first Identifier given to the object. This is the identifier normally displayed in the AIM Dashboard. However, the object may still be referred to and search for using any of its Identifiers.

The AIM Workhub Admin Tool can be used to select a different Identifier as the Preferred Identifier.

Objects Common to Two or More Projects

An object that is common to two separate plants should be given two identifiers, each with the Context of the respective Plant. It does not matter whether the ID is the same or different in each context provided the combined identifiers consisting of Context + ID are unique within the AIM Workhub Database.
