1 The `meta` directive is supplied by the [[!iki plugins/meta desc=meta]] plugin.
3 This directive allows inserting arbitrary metadata into the source of a page.
4 Enter the metadata as follows:
6 \[[!meta field="value"]]
7 \[[!meta field="value" param="value" param="value"]]
9 The first form sets a given field to a given value, while the second form
10 also specifies some additional sub-parameters.
12 The field values are treated as HTML entity-escaped text, so you can include
13 a quote in the text by writing `"` and so on.
19 Overrides the title of the page, which is generally the same as the
22 Note that if the title is overridden, a "title_overridden" variable will
23 be set to a true value in the template; this can be used to format things
24 differently in this case.
28 Specifies a license for the page, for example, "GPL". Can contain
29 WikiLinks and arbitrary markup.
33 Specifies the copyright of the page, for example, "Copyright 2007 by
34 Joey Hess". Can contain WikiLinks and arbitrary markup.
38 Specifies the author of a page.
42 Specifies an url for the author of a page.
46 Specifies a "description" of the page. You could use this to provide
47 a summary, for example, to be picked up by the [[map]] directive.
51 Specifies a permanent link to the page, if different than the page
56 Specifies the creation date of the page. The date can be entered in
57 nearly any format, since it's parsed by [[!cpan TimeDate]].
61 Adds a stylesheet to a page. The stylesheet is treated as a wiki link to
62 a `.css` file in the wiki, so it cannot be used to add links to external
65 \[[!meta stylesheet=somestyle rel="alternate stylesheet"
70 Adds html <link> tags to perform OpenID delegation to an external
71 OpenID server (for `openid` and `openid2`). An optional `xrds-location`
72 parameter lets you specify the location of any [eXtensible Resource
73 DescriptorS](http://www.windley.com/archives/2007/05/using_xrds.shtml).
75 This lets you use an ikiwiki page as your OpenID. Example:
77 \\[[!meta openid="http://joeyh.myopenid.com/"
78 server="http://www.myopenid.com/server"
79 xrds-location="http://www.myopenid.com/xrds?username=joeyh.myopenid.com""]]
81 By default this will delegate for both `openid` and `openid2`. To only
82 delegate for one, add a parameter such as `delegate=openid`.
86 Specifies a link to another page. This can be used as a way to make the
87 wiki treat one page as linking to another without displaying a user-visible
90 \[[!meta link=otherpage]]
92 It can also be used to insert a html <link> tag. For example:
94 \[[!meta link="http://joeyh.myopenid.com/" rel="openid.delegate"]]
96 However, this latter syntax won't be allowed if the
97 [[!iki plugins/htmlscrubber desc=htmlscrubber]] plugin is enabled, since it can be used to
98 insert unsafe content.
102 Causes the page to redirect to another page in the wiki.
104 \[[!meta redir=otherpage]]
106 Optionally, a delay (in seconds) can be specified. The default is to
107 redirect without delay.
109 It can also be used to redirect to an external url. For example:
111 \[[!meta redir="http://example.com/"]]
113 However, this latter syntax won't be allowed if the
114 [[!iki plugins/htmlscrubber desc=htmlscrubber]] plugin is enabled, since it can be used to
115 insert unsafe content.
117 For both cases, an anchor to jump to inside the destination page may also be
118 specified using the common `#ANCHOR` syntax.
122 Causes the robots meta tag to be written:
124 \[[!meta robots="index, nofollow"]]
126 Valid values for the attribute are: "index", "noindex", "follow", and
127 "nofollow". Multiple comma-separated values are allowed, but obviously only
128 some combinations make sense. If there is no robots meta tag, "index,
129 follow" is used as the default.
131 The value is escaped, but its contents are not otherwise checked.
135 Specifies a globally unique ID for a page. This guid should be a URI
136 (in particular, it can be `urn:uuid:` followed by a UUID, as per
137 [[!rfc 4122]]), and it will be used to identify the page's entry in RSS
138 and Atom feeds. If not given, the default is to use the page's URL as its
141 This is mostly useful when a page has moved, to keep the guids for
142 pages unchanged and avoid_flooding_aggregators
143 (see [[!iki tips/howto_avoid_flooding_aggregators]]).
147 Specifies a fake modification time for a page, to be output into RSS and
148 Atom feeds. This is useful to avoid flooding aggregators that sort by
149 modification time, like Planet: for instance, when editing an old blog post
150 to add tags, you could set `updated` to be one second later than the original
151 value. The date/time can be given in any format that
152 [[!cpan TimeDate]] can understand, just like the `date` field.
154 If the field is not one of the above predefined fields, the metadata will be
155 written to the generated html page as a <meta> header. However, this
156 won't be allowed if the [[!iki plugins/htmlscrubber desc=htmlscrubber]] plugin is enabled,
157 since it can be used to insert unsafe content.
159 [[!meta robots="noindex, follow"]]
