Targeted Vocabularies allow you to decide which vocabularies can be applied to an asset type and which vocabularies are required for an asset type. To configure these settings, go to the categories administration page and mouse over the vocabulary in the list until you see the edit icon to the right. Select the icon to reveal a dialog box like the one below.
The default value for Associated Asset Types is All Asset Types. You can
fine tune your choices by using the + and - buttons, which narrows the scope
of the vocabulary to specific assets. In the screenshot above, notice how the
Famous Noses is configured to be available for Blogs and Web
Content, but it is not required. It is mandatory, however, for Documents and
Single and Multi-valued Vocabularies
You can now decide if the user can choose one or more categories from the same vocabulary to categorize an asset. If a vocabulary is single-valued you can only choose one, and if it allows more, you can choose several categories.
Setting vocabulary values is done through the categories administration page. Edit a vocabulary and deselect the Allow Multiple Categories checkbox to set single value vocabularies or use the default option to set multi-value vocabularies.
The third important improvement is every vocabulary has its own separated widget. These widgets appear in the Categorization section of every asset and they allow users to easily select appropriate categories for that asset.
