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"]]
+ \[[!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.
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]] plugin.
+
* permalink
Specifies a permanent link to the page, if different than the page
* date
Specifies the creation date of the page. The date can be entered in
- nearly any format, since it's parsed by [[cpan TimeDate]].
+ nearly any format, since it's parsed by [[!cpan TimeDate]].
* stylesheet
a `.css` file in the wiki, so it cannot be used to add links to external
stylesheets. Example:
- \[[meta stylesheet=somestyle rel="alternate stylesheet"
+ \[[!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:
+ 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"]]
+ \\[[!meta openid="http://joeyh.myopenid.com/"
+ server="http://www.myopenid.com/server"
+ xrds-location="http://www.myopenid.com/xrds?username=joeyh.myopenid.com""]]
* link
wiki treat one page as linking to another without displaying a user-visible
[[ikiwiki/WikiLink]]:
- \[[meta link=otherpage]]
+ \[[!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"]]
+ \[[!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.
Causes the page to redirect to another page in the wiki.
- \[[meta redir=otherpage]]
+ \[[!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/"]]
+ \[[!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.
Causes the robots meta tag to be written:
- \[[meta robots="index, nofollow"]]
+ \[[!meta robots="index, nofollow"]]
Valid values for the attribute are: "index", "noindex", "follow", and
"nofollow". Multiple comma-separated values are allowed, but obviously only
contents. In particular, it does not check the values against the set of
valid values but serves whatever you pass it.
+* 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|tips/howto_avoid_flooding_aggregators]].

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
