Tags

This page is about Freetags, which is the folksonomy implementation of TikiWiki. The name is based on the name of the underlying library from Gordon Luk: http://www.getluky.net/freetag/.

Though similar in function to categories, freetags work somewhat differently. Also, freetags should not be confused with backlinks-to-index style tags discussed further at How To Tag.

Basically folksonomy tagging means/is based on:

• everybody can assign keywords to anything
• bottom-up instead of top-down categorization
• from chaos comes order
• emergent patterns are more powerful than imposition of categories

See: Multilingual tags

Modules

• freetag : that allows to add and remove tag from a current object
• freetags_current : that displays the current tags of an object. Only for a wiki page.
• freetags_prefered : Shows the favorite tags of a user. The number of tags is the value of the parameter rows defined at the module assigment.
• freetags_most_popular: Shows the most popular tags. The number of tags is the value of the parameter rows defined at the module assigment.

User

When offered to do so (for instance, editing wiki pages), just enter your tags into the textfield separated by spaces.

You can browse the available tags by clicking on one, when seeing it somewhere.

It will take you to tiki-browse_freetags.php with the tag centered in the morcego browser, if that feature is enabled.

The syntax of a tag is defined by the admin setting. Tags are separated by space(s). If you want to enter a tag with a space - if the admin setting allows it, you must enclose it into double quotes. Example: in the module freetag, if you enter: "computer science" ibm pc, you will add 3 tags "computer science", "ibm" and "pc"

Admin

In order to go to the admin screen, use this url: tiki-admin.php?page=freetags

Freetag Browsing

• Only accept alphanumeric ASCII freetags (no accents or special chars): If checked all non-alphabetical characters are withdrawn in the tag. Example: free_movie will become freemovie.
• Or valid characters pattern: It is possible if the previous box is not checked to explicitly tell what characters are not wiped off. Only alphanumeric freetags is the pattern a-zA-Z0-9. If you want to include space and _, the pattern can look like a-zA-Z _0-9. For more option http://www.php.net/manual/en/reference.pcre.pattern.syntax.php. The character double quote " can not be included in the pattern as it is the character to delimit tags with space.
• Only accept lowercase freetags Each uppercase character are replaced by the lowercase character. Example: FreeMovie will become freemovie
