A baseline is a special label that can only be added to documents. You create a document baseline to mark an important project milestone. For example, you could create document baselines for an approved design document, a legal reference document, a contract, or a bill of materials. You can use document baselines for internal records and for recording external documents.

To create the baseline, you select the individual documents that are required to represent the information for your milestone. When you baseline, PTC RV&S creates a baseline label on each of the selected documents. Each label contains the same timestamp. Baseline labels appear in the Labels tab in the Item Details view or by viewing document properties. In these views, the Is Baseline column is useful for distinguishing labels associated with a baseline from labels not associated with a baseline.

You can later view the documents included in the baseline by viewing the documents As Of the baseline label. This allows you to view the documents exactly how they existed when the baseline label was created; however, you cannot make any edits to this historical view.

Your administrator determines the item types that allow labels and who can add labels to those items. Labels are one of several attributes that can be configured on a PTC RV&S type. To enable or disable type attributes, see the PTC RV&S Installation and Upgrading Guide.
