These characters fulfill special control and layout functions in the
wiki source code or in PHP. Spaces may be used. They are stored
within the system as an underline. Conversely, this means that underlines
that you use in a title will be displayed as spaces.
The wiki software takes care of formatting the links. It is assumed
that the name of an article is distinct enough to indicate to the reader
what the respective page is about. That is why the page title is simply
used as the link name. Sometimes, however, it can be useful to
have another description. This is the case, for instance, when you
have a hierarchical order of pages for which a link “upwards” in the
structure facilitates navigation. Also, synonymous descriptions, e.g.
“tribe” and “clan,” for two different pages should not be used, since
they indicate the same thing. The necessary separation between link
target and name can be achieved with a so-called “piped link”:
[[page title|description]]
As you can see, a horizontal line (pipe symbol) is placed after the
page title, behind which you can insert a page description that can
consist of one or more words.
Within the context of a sentence, a word can have various forms
based on the rules of grammar. Since all of these forms link to the
same page, the possibility was created to mark only the front part of
a word as a link:
[[Link]]s
In Preview mode, however, the whole word is identified as a link.
The following construction is a rather exaggerated example.
[[caves|cave]][[dwelling]]
Here, two links are included in a single word. The first part of the
word links to “cave”, the second to “dwelling.” One could surely
debate about whether or not such a structure is very useful, especially
since, when looking at it, one cannot detect that two different
links are embedded in the word. However, the point is that it is possible.
Now it is time to give our wiki example some structure. We can
divide the wiki into assorted pages that fulfill various tasks.
