127 uf_xfolk_meta - plugin to create a 'xfolk' (bookmark) microformat tag
132 uf_xfolk_meta is a plugin to create an 'xfolk' (bookmark) microformat tag
133 from metadata in your post. The microformat tag is created in the
134 $uf_xfolk_meta::xfolk variable for use in templates or by other plugins,
135 or if the 'auto_append_to_body' config variable is set (it is by default),
136 uf_xfolk_meta will append the tag to your story body automatically.
138 =head2 REQUIRED METADATA ITEMS
142 =item url (or taggedlink)
144 The URL for the bookmarked page.
148 The title to use for the bookmarked page.
152 If any required metadata is missing the plugin just skips the story.
154 =head2 OPTIONAL METADATA ITEMS
160 Comma-separated list of tags applying to the bookmarked page.
164 Description or summary of the bookmarked page.
168 =head2 Config Elements
170 uf_xfolk_meta also supports a couple of config elements that can be used to
171 override plugin config data on a per-story basis:
175 =item XFolk-Class (metamail) / xfolk_class (meta)
177 This class (or list of classes) is appended to the class list applied to the
178 top-level xfolk element in the rendered xfolk i.e. it overrides the
179 'class' config variable.
181 =item XFolk-Autoappend (metamail) / xfolk_autoappend (meta)
183 This is a flag (0 or 1) indicating whether the rendered xfolk should be
184 automatically appended to the story body. It overrides the 'auto_append_to_body'
187 =item XFolk-Style (metamail) / xfolk_style (meta)
189 One of the following styles: 'div-span', 'ul', 'dl', used to render the xfolk.
190 It overrides the 'style' config variable.
196 uf_xfolk_meta should be loaded after the meta plugins (meta
197 itself, or the metaclear/metamail/metadir/metafile family).
