 ====== Namespace Templates ======
-Sometimes you might want to have every page in a certain namespace based on a common skeleton. For example, in the ''address'' namespace you could have an already prepared table, which only needs to be filled with data. This can be easily achieved with so called "namespace templates".
+Dokuwiki supports scaffolding. Sometimes you might want to have every page in a certain namespace based on a common skeleton. For example, in the ''address'' namespace you could have an already prepared table, which only needs to be filled with data. This can be easily achieved with so called "namespace templates".
 When a page is created, [[DokuWiki]] looks up whether a template file exists and it shows it within the editor window. The templates therefore are .txt files and should contain wiki markup.
 ===== Template files =====
 Two kinds of template files can be used:
-  * ''_template.txt'', which are used in the current namespace.
+  * ''_template.txt'', which will be used in the current namespace (but not below).
-  * ''%%__%%template.txt'' (two leading underscores), which work as the normal ''_template.txt'' files apart from the fact they are used in all namespaces below as well (they are inherited).
+  * ''%%__%%template.txt'' (note the two leading underscores), will cover the current namespace and all namespaces below as well (thus this kind of template will be inherited).
+If both (normal and inherited) templates are present in the same namespace, the normal ''_template.txt'' will take precedence when a new page is created. This allows the pages of the top namespace to be differentiated from all pages of any sub-namespaces inherited below, which could become quite handy.
-If both (inherited and normal) templates are present in a namespace, the normal one is taken.
+**NOTE:** Any changes to a.m. template files will //only effect newly created pages// and existing pages are always left untouched.

   - use the wiki to save a page with the content that you want to use as a template into the appropriate namespace

+  - use FTP or WebDAV to rename it as _template.txt

+However, one should prefer the [[plugin:TemplatePagename]] Plugin if possible (see explanations below).
 ===== Syntax =====
 The content of the file is just standard [[wiki:syntax|wiki markup]].

+==== Troubleshooting ====
-===== @GROUPS@ support =====
+Problem: An unexpected error occurs "no timestamp" when server (Linux Ubuntu) cannot write the directory ''/dokuwiki/data/pages/namespace''. This might happen, when the namespace directory is created by the admin as ''<root>'' in order to put the namespace template file in ''/dokuwiki/data/pages/namespace/'', before creating the first page.
-It may be interesting to have support for the ''@GROUPS@'' keyword to extend to the group list of the user creating the page (e.g. to specify a set of tags on a user's home page). The following patch implements it.

+. Solution: Before establishing the hidden template file, first create a dummy page via the DokuWiki GUI, like so: ''yourserver/doku.php?id=namespace:dummy&do=edit''. This allows DokuWiki to create the namespace directory under own control and assures full write permissions for DokuWiki on the created directory.

+. Solution: The admin ''<root>'' should be able to change //owner and group// settings through the [[https://askubuntu.com/a/6727|chown command]] (e.g., ''chown www-data:www-data /dokuwiki/data/pages/namespace/'' on CLI) and in the first place should establish new directories and files with ''owner:group'' settings applicable to the DokuWiki installation anyway.
