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.
26 An optional `sort` parameter will be used preferentially when
27 [[ikiwiki/pagespec/sorting]] by `meta_title`:
29 \[[!meta title="The Beatles" sort="Beatles, The"]]
31 \[[!meta title="David Bowie" sort="Bowie, David"]]
35 Specifies a license for the page, for example, "GPL". Can contain
36 WikiLinks and arbitrary markup.
40 Specifies the copyright of the page, for example, "Copyright 2007 by
41 Joey Hess". Can contain WikiLinks and arbitrary markup.
45 Specifies the author of a page.
49 Specifies an url for the author of a page.
53 Specifies a short description for the page. This will be put in
54 the html header, and can also be displayed by eg, the [[map]] directive.
58 Specifies a permanent link to the page, if different than the page
63 Specifies the creation date of the page. The date can be entered in
64 nearly any format, since it's parsed by [[!cpan TimeDate]].
68 Adds a stylesheet to a page. The stylesheet is treated as a wiki link to
69 a `.css` file in the wiki, so it cannot be used to add links to external
72 \[[!meta stylesheet=somestyle rel="alternate stylesheet"
77 Adds html <link> tags to perform OpenID delegation to an external
78 OpenID server. This lets you use an ikiwiki page as your OpenID.
80 By default this will delegate for both `openid` and `openid2`. To only
81 delegate for one, add a parameter such as `delegate=openid`.
83 An optional `xrds-location`
84 parameter lets you specify the location of any [eXtensible Resource
85 DescriptorS](http://www.windley.com/archives/2007/05/using_xrds.shtml).
89 \\[[!meta openid="http://joeyh.myopenid.com/"
90 server="http://www.myopenid.com/server"
91 xrds-location="http://www.myopenid.com/xrds?username=joeyh.myopenid.com""]]
95 Specifies a link to another page. This can be used as a way to make the
96 wiki treat one page as linking to another without displaying a user-visible
99 \[[!meta link=otherpage]]
101 It can also be used to insert a html <link> tag. For example:
103 \[[!meta link="http://joeyh.myopenid.com/" rel="openid.delegate"]]
105 However, this latter syntax won't be allowed if the
106 [[!iki plugins/htmlscrubber desc=htmlscrubber]] plugin is enabled, since it can be used to
107 insert unsafe content.
111 Causes the page to redirect to another page in the wiki.
113 \[[!meta redir=otherpage]]
115 Optionally, a delay (in seconds) can be specified. The default is to
116 redirect without delay.
118 It can also be used to redirect to an external url. For example:
120 \[[!meta redir="http://example.com/"]]
122 However, this latter syntax won't be allowed if the
123 [[!iki plugins/htmlscrubber desc=htmlscrubber]] plugin is enabled, since it can be used to
124 insert unsafe content.
126 For both cases, an anchor to jump to inside the destination page may also be
127 specified using the common `#ANCHOR` syntax.
131 Causes the robots meta tag to be written:
133 \[[!meta robots="index, nofollow"]]
135 Valid values for the attribute are: "index", "noindex", "follow", and
136 "nofollow". Multiple comma-separated values are allowed, but obviously only
137 some combinations make sense. If there is no robots meta tag, "index,
138 follow" is used as the default.
140 The value is escaped, but its contents are not otherwise checked.
144 Specifies a globally unique ID for a page. This guid should be a URI
145 (in particular, it can be `urn:uuid:` followed by a UUID, as per
146 [[!rfc 4122]]), and it will be used to identify the page's entry in RSS
147 and Atom feeds. If not given, the default is to use the page's URL as its
150 This is mostly useful when a page has moved, to keep the guids for
151 pages unchanged and avoid_flooding_aggregators
152 (see [[!iki tips/howto_avoid_flooding_aggregators]]).
156 Specifies a fake modification time for a page, to be output into RSS and
157 Atom feeds. This is useful to avoid flooding aggregators that sort by
158 modification time, like Planet: for instance, when editing an old blog post
159 to add tags, you could set `updated` to be one second later than the original
160 value. The date/time can be given in any format that
161 [[!cpan TimeDate]] can understand, just like the `date` field.
163 If the field is not one of the above predefined fields, the metadata will be
164 written to the generated html page as a <meta> header. However, this
165 won't be allowed if the [[!iki plugins/htmlscrubber desc=htmlscrubber]] plugin is enabled,
166 since it can be used to insert unsafe content.
168 [[!meta robots="noindex, follow"]]
