Semantic link plugin

• Usability
• Feature request

Semantic link relationships seem until now only browsable by admins.
Since there is - besides the admin view - no other way to get the semantic relations listed, no one else can get advantage of semantic links and will make no efforts in setting semantic relations.
Concidering the importance of semantics in wikis a plugin seems highly necessary to get the feature of semantic links in tiki started.

Request:
Likewise to the Plugin Backlinks all pages that link to a specific page in a specific semantic relationship.

So far:
The semantic_links module is supposed to enable views on semantic relationships.
And indeed, when selecting a semantic type and push the button "show usage", the result shown is exactly what I need.
However this view is only possible for admins.
But since that view for admins is already existing, I would estimate the efforts to implement a plugin as low.

Plugin idea:
Relating to the example shown in the documentation of SemanticAdmin dogs and cats are subsets of animals.
We want the page "animals" to list all subsets by a plugin likewise to

{SEMANTICLINKS (semantictype=subset, page=animals, info=hits|user, noheader=1}
{SEMANTICLINKS}

The result would be:
- dogs
- cats

Insufficient workarounds:
Until now the above shown results have to be specified manually as invert relations.
For automatic listing, existing plugins PluginShowpages / PluginListpages / PluginSearchtitles do not work.
So the only workaround without the requested plugin I could image would be to tag the pages "dogs" and "cats" with the a tag "subset-animal" and than use freetags plugin for a listing dogs and cats in the animal wikipage - likewise to the status tags in this tiki. However, that sounds like a bad abuse of tags, since we already got that information saved in our semantic links relationship - we just need to get it readable.
