+[[tag type/meta]]
+
This plugin allows inserting arbitrary metadata into the source of a page.
Enter the metadata as follows:
The first form sets a given field to a given value, while the second form
also specifies some additional sub-parameters.
+The field values are treated as HTML entity-escaped text, so you can include
+a quote in the text by writing `"` and so on.
+
You can use any field names you like, but here are some predefined ones:
* 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
+ wiki treat one page as linking to another without displaying a user-visible
+ [[WikiLink]]:
- \[[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
+ be set to a true value in the template; this can be used to format things
+ differently in this case.
+
* license
- Specifies a copyright license for the page, for example, "GPL".
+ Specifies a license for the page, for example, "GPL". Can contain
+ WikiLinks.
+
+* copyright
+
+ Specifies the copyright of the page, for example, "Copyright 2007 by
+ Joey Hess". Can contain WikiLinks.
* 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:
+
+ \\[[meta openid="http://joeyh.myopenid.com/"
+ server="http://www.myopenid.com/server"]]
-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)"]]
+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.
