DokuWikiでは、ページをカテゴリに分けるため、“名前空間”と呼ばれるものを使用します。

名前空間を作成する手順が別に用意されているわけではありません。ページ名にコロンを付けてページを作成するだけです。最後のコロンの後ろのものがページの名前そのものになります。その他のものが名前空間です。存在しないページ名に含まれるすべての名前空間は、自動的にDokuWikiによって作成されます。

名前空間内のすべてのページが削除されたとき、名前空間は論理的に存在しなくなります。DokuWikiは通常、同様に空のディレクトリを削除します。

PageMove pluginを使うと、古い名前空間から新しい名前空間へページを移動することができます。必要であればドキュメントを参考にしてください。

The manual way is more difficult:

• Rename the folders that represent the namespace in:
  • data/pages
  • data/media (if this exists)
• Remove metadata for the namespace under data/meta
• Remove attic data for the namespace under data/attic

For example, on a Unix host, you could:

• mv /dokuwiki_base/data/pages/old_namespace /dokuwiki_base/data/pages/new_namespace
• mv /dokuwiki_base/data/media/old_namespace /dokuwiki_base/data/media/new_namespace
• rm -Rf /dokuwiki_base/data/meta/old_namespace
• rm -Rf /dokuwiki_base/data/attic/old_namespace

Note that the old_namespace and/or new_namespace words may need to be encoded if they are on a non-latin character set (ie Greek, Russian etc).

• Correct (by editing them) all the links to the pages under the moved namespace (you can discover those before moving the namespace by reviewing each page's backlinks).

• Browse each and every page under the new namespace. This will create the missing indexing information and metadata for the pages under the moved namespace.

However, you will still have lots of junk left around. For example in data/changes.log, various files under cache (including the .idx files etc). If possible you could just start from a blank state as follows (again under Unix) but be warned that this will mean losing all your historical information (ie recent changes):

• cat /dev/null > /dokuwiki_base/data/changes.log
• rm -Rf /dokuwiki_base/data/attic/*
• rm -Rf /dokuwiki_base/data/cache/?
• rm -Rf /dokuwiki_base/data/cache/*.idx
• rm -Rf /dokuwiki_base/data/cache/purgefile
• Browse each and every page of your Wiki.

I understand this is convoluted (and maybe I missed/messed a couple of things you should also do). All in all this is a PITA. You may also use a couple of plugins that are available for (re)building the searchindex for the complete wiki, erasing entire cache and/or old wiki revisions thus avoiding to do this manualy.

It is possible to link to a default file of a namespace ending the linkid with a colon: [[foo:bar:]]. To which page the link links is dependent on the existance of certain named files. For [[foo:bar:]] the following pages are checked:

foo:bar:$conf['start']
foo:bar:bar
foo:bar

The pages are checked in that order and whatever page is found first will be linked to. Autoplural linking is not done for those links

This feature is only available in 2006-09-28 RC1 version and above.
