Having open-ended values for criteria such as query-parameters can be confusing for marketers. There should be a way to limit values to predefined options.
A good example is Device Brand (or worse Device Model) criteria. There is no real way for a marketing person to have a firm grasp of what the allowable values for this field could or should be. The taxonomy of values should be defined by a domain expert which the marketing person can then refer to easily.
A second benefit is reusing the same taxonomy in various places across a site or portal instance.
The segment designer should not have to keep track of taxonomy of values for concepts foreign to them when building criteria.
- when creating a condition whose input is free-form it should be possible to draw from an established taxonomy
- accessing a given taxonomy should be easy and intuitive
- defining a taxonomy should not require software development
- taxonomies should be available across multiple input scenarios besides
- content creation
- content filtering
- configuration management
- user segmentation
