> And this is an illustration why a clean work-around (without changing the software) is not possible: while thinking about [[todo/matching_different_kinds_of_links]], I thought one could work around the problem by simply explicitly including the kind of the relation into the link target (like the tagbase in tags), and by having a separate page without the "tagbase" to link to when one wants simply to refer to the tag without tagging. But this won't work: one has to at least once refer to the real tag page if one wants to talk about it, and this reference will count as tagging (unwanted). --Ivan Z.
> But well, perhaps there is a workaround without introducing different kinds of links. One could modify the [[tag plugin|plugins/tag]] so that it adds 2 links to a page: for tagging -- `tagbase/TAG`, and for navigation -- `tagdescription/TAG` (displayed at the bottom). Then the `tagdescription/TAG` page would hold whatever list one wishes (with `tagged(TAG)` in the pagespec), and whenever one wants to merely refer to the tag, one should link to `tagdescription/TAG`--this link won't count as tagging. So, `tagbase/TAG` would become completely auxiliary (internal) link targets for ikiwiki, the users would edit or link to only `tagdescription/TAG`. --Ivan Z.

* "`postcomment(glob)`" - matches only when comments are being
posted to a page matching the specified glob
+* "`typedlink(type glob)`" - matches pages that link to a given page (or glob)
+ with a given link type. Plugins can create links with a specific type:
+ for instance, the tag plugin creates links of type `tag`.
For example, to match all pages in a blog that link to the page about music
and were written in 2005:
It also provides the `tagged()` [[ikiwiki/PageSpec]], which can be used to
match pages that are tagged with a specific tag.
+If the `tagged_is_strict` config option is set, `tagged()` will only match
+tags explicitly set with [[ikiwiki/directive/tag]] or
+[[ikiwiki/directive/taglink]]; if not (the default), it will also match
+any other [[WikiLinks|ikiwiki/WikiLink]] to the tag page.
+
[[!if test="enabled(tag)" then="""
This wiki has the tag plugin enabled, so you'll see a note below that this
page is tagged with the "tags" tag.
$links{"foo"} = ["bar", "baz"];
+### `%typedlinks`
+
+The `%typedlinks` hash records links of specific types. Do not modify this
+hash directly; call `add_link()`. The keys are page names, and the values
+are hash references. In each page's hash reference, the keys are link types
+defined by plugins, and the values are hash references with link targets
+as keys, and 1 as a dummy value, something like this:
+
+ $typedlinks{"foo"} = {
+ tag => { short_word => 1, metasyntactic_variable => 1 },
+ next_page => { bar => 1 },
+ };
+
+Ordinary [[WikiLinks|ikiwiki/WikiLink]] appear in `%links`, but not in
+`%typedlinks`.
+
### `%pagesources`
The `%pagesources` has can be used to look up the source filename
filename of the page. For example, `targetpage("foo", "rss", "feed")`
will yield something like `foo/feed.rss`.
-### `add_link($$)`
+### `add_link($$;$)`
This adds a link to `%links`, ensuring that duplicate links are not
added. Pass it the page that contains the link, and the link text.
+An optional third parameter sets the link type (`undef` produces an ordinary
+[[ikiwiki/WikiLink]]).
