[[template id=plugin name=meta author="[[Joey]]"]]
[[tag type/meta]]
This plugin allows inserting arbitrary metadata into the source of a page.
Enter the metadata as follows:
\[[meta field="value"]]
\[[meta field="value" param="value" param="value"]]
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 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=otherpage]]
It can also be used to insert a html <link> tag. For example:
\[[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 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.

* 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"]]
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.
