* 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).
- \\[[meta openid="http://joeyh.myopenid.com/"
- server="http://www.myopenid.com/server"]]
+ 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
For both cases, an anchor to jump to inside the destination page may also be
specified using the common `PAGE#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 plugin escapes the value, but otherwise does not care about its
+ contents. In particular, it does not check the values against the set of
+ valid values but serves whatever you pass it.
+
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
