The taxonomy module is one of the most popular features because librarians often want to create categories to organize content by type. Librarians can also use categories to help in site navigation. The taxonomy module can automatically classify new content, which is very useful for organizing content on the fly. A simple example would be organizing a list of music reviews by musical genre.

The taxonomy module allows you to define vocabularies (sets of categories), which are used to classify content. The module supports hierarchical classification and association between terms, allowing for truly flexible information retrieval and classification.

The taxonomy module allows multiple lists of categories for classification (controlled vocabularies) and offers the possibility of creating thesauri (controlled vocabularies that indicate the relationship of terms) and taxonomies (controlled vocabularies where relationships are indicated hierarchically).

A controlled vocabulary is a set of terms to use for describing content (known as descriptors in indexing lingo). LibrarySite 2 allows you to tag each piece of content (blog, story, etc.) using one or many of these terms. For simple implementations, you might create a set of categories without subcategories. For more complex implementations, you might create a hierarchical list of categories. Sites can also use folksonomies. By checking the "Free tagging" option when creating a vocabulary, users can create and enter their own tags for their content. You can:

• add a vocabulary at administer >> categories >> add vocabulary
• administer taxonomy at administer >> categories
• restrict content access by category for specific users roles using the taxonomy access module
• build a custom view of your categories using the taxonomy browser.

Taxonomy allows you to classify postings under different categories.

• Go to administer >> categories
• Select the Add Vocabularies tab.
• Vocabulary name: Chose the name of the group that you want to categorize (for example World and then you would have countries as terms).
• You can add help text and description.
• Help text appears below the category select box when the content creator posts their submission.
• Description appears on the Edit Vocabulary page and allows you to add information about the vocabulary.
• Select the content types that you want to use this vocabulary for.
• Hierarchy
• Disabled
• Single
• Allows you to categorize items in a tree i.e. North America/USA/California/Los Angeles/Mar Vista
• They appear in a drop down list.
• Multiple
• A term can have more than one item as its parent.
• Terms appear in a select box. You use control/highlight to select multiple items.
• Related terms
• Allows related terms in the vocabulary
• Free tagging
• Content is categorized by typing terms instead of choosing from a list.
• Multiple select
• Allows nodes to have more than one term from a vocabulary (always true for free tagging). For example: Main and West Branches
