Labels

A Helix Server label is a set of tagged file revisions. For example, you might want to tag the file revisions that compose a particular release with the label release2.0.1. You can use labels to:

• Keep track of all the file revisions contained in a particular release of software.
• Distribute a particular set of file revisions to other users. For example, a standard configuration.
• Populate a clean build workspace.
• Specify a set of file revisions to be branched for development purposes.
• Sync the revisions as a group to a client workspace.

Labels and changelist numbers differ:

Label	Changelist
A label can refer to any set of file revisions. If you need to refer to a group of file revisions from different points in time, use a label.	A changelist number refers to the contents of all the files in the depot at the time the changelist was submitted. If there is a point in time at which the files are consistent for your purposes, use a changelist number.
You can change the contents of a label.	You cannot change the contents of a submitted changelist.
You can assign your own names to labels.	Helix Server assigns each changelist number.

There are two types of labels: static and automatic. See Static versus automatic labels for a discussion of their differences.
