 * link
 

-  Specifies a link to another page. This is used to generate a html
-  <link> tag, and also as a way to make the wiki treat one page as
-  linking to another without displaying a user-visible link. The latter 
-  can be useful when using links to categorise pages. A html link tag
-  would look like this:
+  Specifies a link to another page. This can be used as a way to make the

-       \[[meta link="foo.css" rel="stylesheet" type="text/css"]]
+       \[[meta link=otherpage]]

 
 

-  A non-user-visible [[WikiLink]] would instead look like this:
+  It can also be used to insert a html <link> tag. For example:

 
 

-       \[[meta link=otherpage]]
+       \[[meta link="http://joeyh.myopenid.com/" rel="openid.delegate"]]
+
+  However, this latter syntax won't be allowed if the [[htmlscrubber]] is
+  enabled, since it can be used to insert unsafe content.

 
 * title
 
   Overrides the title of the page, which is generally the same as the
   page name.

+  Note that if the title is overridden, a "title_overridden" variable will

+  differently in this case.

+  Specifies a license for the page, for example, "GPL". Can contain

+
+* copyright
+
+  Specifies the copyright of the page, for example, "Copyright 2007 by
+  Joey Hess". Can contain WikiLinks.

 
 * author
 
   Specifies the author of a page.
 
 
 * author
 
   Specifies the author of a page.
 

-If the field is not treated specially (as the link and title fields are),
-the metadata will be written to the generated html page as a <meta>
-header.
+* authorurl
+
+  Specifies an url for the author of a page.
+
+* permalink
+
+  Specifies a permanent link to the page, if different than the page
+  generated by ikiwiki.
+
+* date
+
+  Specifies the creation date of the page. The date can be entered in
+  nearly any format, since it's parsed by [[cpan TimeDate]].
+
+* stylesheet
+
+  Adds a stylesheet to a page. The stylesheet is treated as a wiki link to
+  a `.css` file in the wiki, so it cannot be used to add links to external
+  stylesheets. Example:
+
+       \[[meta stylesheet=somestyle rel="alternate stylesheet"
+       title="somestyle"]]
+
+* openid
+
+  Adds html <link> tags to perform OpenID delegation to an external
+  OpenID server. This lets you use an ikiwiki page as your OpenID. Example:

 
 

-This plugin is included in ikiwiki, but it is not enabled by default. If
-it is enabled, the title of this page will say it is.
-[[meta title="meta plugin (enabled)"]]
+       \\[[meta openid="http://joeyh.myopenid.com/"
+       server="http://www.myopenid.com/server"]]

 
 

-[[tag plugins/type/meta]]
+If the field is not one of the above predefined fields, the metadata will be
+written to the generated html page as a <meta> header. However, this
+won't be allowed if the [[htmlscrubber]] is enabled, since it can be used to
+insert unsafe content.
