- -Classifying nodes allows for the organization of content into categories and subcategories of description. These categories can be used to organize and retrieve similarly described content. Drupal's classifier module is an extremely flexible classification system that allows for 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).

- -Vocabularies
When you create a controlled vocabulary you are creating a set of terms to use for describing content (known as descriptors in indexing lingo). Drupal allows you to describe each node of content (blog, story, etc.) that you submit to Drupal using one or many of these terms. For simple implementations, you might create a set of categories without subcategories, similar to Slash's "Sections". For more complex implementations, you might create a hierarchical list of categories for describing content.

- -Setting up a vocabulary
When you set up a controlled vocabulary, you will be asked to enter some descriptive data and define the attributes of this vocabulary. For example, if you select the "Hierarchy" option, you will be defining a taxonomy or thesaurus. If you select "Relationships" you are allowing the definition of related terms as in a thesaurus. Selecting "Multiple Select" will allow you to describe a node using more than one term.

- -Vocabulary name
Required. The name for this vocabulary. Example: 'Topic'.

- -Description
Optional. Description of the vocabulary, can be used by modules.

- -Types
Required. A comma-seperated list of node types you want to associate this vocabulary with. Available types: blog, book, forum, page, story.

- -Relationships
Allows relationships between terms within this vocabulary. This is synonymous with "See also" type references.

- -Hierarchy
Allows a tree-like hierarchy

- -Multiple Select
Allows nodes to be described using more than one term.

- -Adding terms to a vocabulary
The options you see when adding a term to a vocabulary will depend on what you selected for "Relationships", "Hierarchy" and "Multiple Select" when you created the vocabulary.

- -Term name
Required. The name for this term. Example: 'Linux'.

- -Description
Optional. Description of the term, can be used by modules. This is synonymous with a "Scope note".

- -Relationships
Optional. Select one or many related terms.

- -Parent
Select the term under which this term is a subset -- the branch of the hierarchy this term belongs under. This is also known as the "Broader term" indicator used in thesauri.

- -Synonyms
Enter synonyms for this term, one synonym per line. Synonyms can be used for variant spellings, acronyms, and other terms that have the same meaning as the added term, but which are not explicitly listed in this thesaurus (unauthorized terms). - Enter synonyms for this term, one synonym per line.

Background

+ Classifying nodes allows for the organization of content into categories and + subcategories of description. These categories can be used to organize and retrieve + similarly described content. Drupal's taxonomy.module is an extremely flexible + classification system that allows for 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). For details about + classification + types and insight into the development of taxonomy.module, see this + drupal.org discussion.
+

An Example Taxonomy - Foods

+

Dairy
+ --Milk
+ Drink
+ --Alchohol
+ --Pop
+ --Milk
+ Meat
+ --Beef
+ --Chicken
+ --Lamb
+ Spices
+ --Sugar

+

Notes

+
    +
  • The term Milk appears within both Dairy and Drink. + This is an example of Multiple Parents for a term.
    • +
  • The order of siblings (e.g. Beef, Chicken, Lamb) in + the taxonomy may be controlled with the Weight parameter.
    • +
+

+

Vocabularies

+ When you create a controlled vocabulary you are creating a set of terms to use + for describing content (known as descriptors in indexing lingo). Drupal allows + you to describe each node of content (blog, story, etc.) + using one or many of these terms. For simple implementations, you might + create a set of categories without subcategories, similar to Slashdot's "Sections". + For more complex implementations, you might create a hierarchical list of categories + such as the example Food taxonomy above. + +

Setting up a vocabulary

+

When you set up a controlled vocabulary, you will be asked to enter some descriptive + data and define the attributes of this vocabulary. For example, if you select + the Hierarchy option, you will be defining a taxonomy or a thesaurus. If + you select Related Terms option, you are allowing the definition of related + terms as in a thesaurus. Selecting Multiple Select will allow you to describe + a node using more than one term. That node will then appear in each term's page, + thus increasing the chance that a user will find it.

+ Vocabulary name
+ Required. The name for this vocabulary. Example: Dairy.
+
+ Description
+ Optional. Description of the vocabulary, can be used by modules and feeds.
+
+ Types
+ Required. The list of node types you want to associate this vocabulary + with. Some available types are: blog, book, forum, page, story.
+
+ Related Terms
+ Allows relationships between terms within this vocabulary. Think of these as + See also references.
+
+ Hierarchy
+ Allows a tree-like taxonomy, as in our Foods example above
+
+ Multiple Select
+ Allows nodes to be described using more than one term. Nodes may then appear on + multiple taxonomy pages.
+

Adding terms to a vocabulary

Displaying Nodes Organized by Term(s)

+

In order to view the nodes associated with a term or a collection of terms, you + should browse to a properly formed URL. For example, see + "node", "or" => "1,2"), "module"); ?>"> "node", "or" => "1,2"), "module"); ?>. + Taxonomy URLs always contain a termID or list of termIDs at the end of the URL (aka querystring). + You may learn the termID for a given term by hovering over that term in the "taxonomy")) ?> page in the Admin and noting the number after the querystring parameter called tid. + If you wish to see nodes from a collection of termIDs, separate each termID with a comma. + Also, the name of the querystring parameter may be or or and. + or shows nodes which appear in any of the termIDs while and shows nodes in all the specified termIDs. + Thus, or is less specific than and. +

+ +

RSS Feeds

+

Every term, or collection of terms, provides an RSS feed to which interested + users may subscribe. The URL format for an sample RSS feed is + "node", "op" => "feed", "or" => "1,2"), "module"); ?>"> "node", "op" => "feed", "or" => "1,2"), "module"); ?>.
