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