-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.
-
-Supported fields:
-
-* 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 and arbitrary markup.
-
-* copyright
-
- Specifies the copyright of the page, for example, "Copyright 2007 by
- Joey Hess". Can contain WikiLinks and arbitrary markup.
-
-* 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 (for `openid` and `openid2`). An optional `xrds-location`
- parameter lets you specify the location of any [eXtensible Resource
- DescriptorS](http://www.windley.com/archives/2007/05/using_xrds.shtml).
-
- This lets you use an ikiwiki page as your OpenID. Example:
-
- \\[[!meta openid="http://joeyh.myopenid.com/"
- server="http://www.myopenid.com/server"
- xrds-location="http://www.myopenid.com/xrds?username=joeyh.myopenid.com""]]
-
-* 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
- [[ikiwiki/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.
-
-* redir
-
- Causes the page to redirect to another page in the wiki.
-
- \[[!meta redir=otherpage]]
-
- Optionally, a delay (in seconds) can be specified. The default is to
- redirect without delay.
-
- It can also be used to redirect to an external url. For example:
-
- \[[!meta redir="http://example.com/"]]
-
- However, this latter syntax won't be allowed if the [[htmlscrubber]] is
- enabled, since it can be used to insert unsafe content.
-
- For both cases, an anchor to jump to inside the destination page may also be
- specified using the common `PAGE#ANCHOR` syntax.
-
-* robots
-
- Causes the robots meta tag to be written:
-
- \[[!meta robots="index, nofollow"]]
-
- Valid values for the attribute are: "index", "noindex", "follow", and
- "nofollow". Multiple comma-separated values are allowed, but obviously only
- some combinations make sense. If there is no robots meta tag, "index,
- follow" is used as the default.
-
- The plugin escapes the value, but otherwise does not care about its
- contents. In particular, it does not check the values against the set of
- valid values but serves whatever you pass it.
-
-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.
