Setting this option will mean that all successful builds will be tagged in Dimensions as a baseline. This will mean that you have a baseline asset representing this build that can then be used at a future date.

The baseline identifier that gets created is fixed at
    [PRODUCT:PROJECTID]_[HUDSON_PROJECT]_[BUILDNO]

where
    [PRODUCT:PROJECTID] is the name of the Dimensions project or stream being monitored.
    [HUDSON_PROJECT]      is the name of the build project
    [BUILDNO]                    is the build number

If a baseline identifier template is specified however, then the baseline identifier that gets created will reflect that template.

(Note - For the baseline to be successfully created, the name of the build project must comply to Dimensions naming conventions).
