The meta directive is supplied by the meta plugin.

This directive 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.

• description

  Specifies a "description" of the page. You could use this to provide a summary, for example, to be picked up by the map directive.

• 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 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.

  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 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 plugin 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 plugin 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 #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 value is escaped, but its contents are not otherwise checked.

• guid

  Specifies a globally unique ID for a page. This guid should be a URI (in particular, it can be urn:uuid: followed by a UUID, as per RFC 4122), and it will be used to identify the page's entry in RSS and Atom feeds. If not given, the default is to use the page's URL as its guid.

  This is mostly useful when a page has moved, to keep the guids for pages unchanged and avoid_flooding_aggregators (see tips/howto avoid flooding aggregators).

• updated

  Specifies a fake modification time for a page, to be output into RSS and Atom feeds. This is useful to avoid flooding aggregators that sort by modification time, like Planet: for instance, when editing an old blog post to add tags, you could set updated to be one second later than the original value. The date/time can be given in any format that TimeDate can understand, just like the date field.

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 plugin is enabled, since it can be used to insert unsafe content.
