 > 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.
