Concept: Attributes

Attributes are groupings with lists of values. Example: An attribute, called Product Groups, has these values:

Tops
Bottoms
Accessories

Attributes tag metadata. Example: Attributes tag accounts, custom dimensions, and levels. Tagging metadata enables you to create different groupings and hierarchies. Example: Product Group is a dimension attribute that you use to tag the product dimensions. You can tag the T-shirt product with Tops, and the Shorts product with Bottoms.

Because attributes categorize metadata, they have the effect of categorizing the related data. Your team doesn't have to tag their entries in sheets with the attribute. The attribute values associate with the account, dimension, or level automatically. Attributes don't tag the actual data, which also makes it easy to delete the attributes and attribute values.
