Hi Unclegeo,

regarding the inconsistent behavior when creating the usual Wiki-links, you should check if emptying the TikiCache leads to more predictable results.

You'll find the TikiCache admin panel by calling tiki-admin_system.php (append this to your installation's URL).

Click the waste baskets to empty the respective cache.

If this causes the disregarded links to be properly updated afterwards, then we at least know that something is wrong here (though knowing so alone will of course not solve the problem in itself).

Which Tiki version do you use, btw? –

Regarding semantic links, pls. see

• http://doc.tiki.org/Semantic

Semantic links let you define the precise meaning (= semantic) of links between two pages. That is, you not only indicate »Those two pages are somehow related« like you would do with a usual link, but you would state that (for example)

• Dodo –––is-a–––) Bird
  • Reverse: Dodo (–––has-instance––– Bird

or

• Foo Inc. –––owns-shares-of–––) Bar Ltd.
  • Reverse: Foo Inc. (–––owned-by––– Bar Ltd.

or

• Peter –––has-daughter–––) Mary
  • Reverse: Peter (–––has-parent––– Mary

or

• OR –––abreviates–––) Oregon
  • Reverse: OR (–––abreviated––– Oregon

Another way to conceive of semantic links is to imagine them as being »typed links«.

One of Tiki's modules presents the semantic links contained in the wiki page currently displayed (in addition to them being displayed like usual links in the page's running text).

We use this module, naming it »Kurzinfo« (german for »quick info«, or »short info«).

But if me manage to export the semantic links from Tiki or the database,

then we could easily use GraphViz,

• http://en.wikipedia.org/wiki/Graphviz

to visualize the semantic link data as a graphical semantic network like in this article:

Nice, right? =;-)

Take care,
