---+ Managing Webs
_Adding, renaming and deleting webs are all web-based operations._
%TOC%
---++ Overview
A TWikiSite is divided into webs; each one represents one workspace, one area of collaboration. Each web is a container for topics. Each topic is a container for page content and attachments. Administrators can add/rename/delete webs.
#NamespaceAndURL
---++ Namespace and URL
The name of the web and topic is represented in the page URL. For example, =http://twiki.example.com/do/view/Sandbox/WebNotify= tells us that we __view__ topic __WebNotify__ located in the __Sandbox__ web.
%T% __Tip:__ The URL of a web's homepage ends in =/%HOMETOPIC%= by default. The name of the homepage topic can safely be omitted to make for shorter and more legible links. For example, =http://twiki.example.com/do/view/Sandbox= links to the homepage of the Sandbox web.
#WebTemplate
---++ Choose Web Template
New webs are based on a web you specify. There are two types of webs you can use to create a new web:
* Use a specially designed TemplateWeb. This is an invisible web that begins with an underscore "_" character (for example =_default=).
* Use an existing web as a template web. This may be useful if you already have a web that you would like to use as a starting point.
In either case all topics in the template web will be copied into the new web. Make sure to verify that your new web has all the custom modifications that you desire. Any settings defined in the form below will automatically be set in the !WebPreferences of the new web.
#CreateNewWeb
---++ Adding a New Web
__Notes:__
* You must have =ROOTCHANGE= access to create a top-level web (one with no parent)
* Only the person who created it has permission to change the %WEBPREFSTOPIC% in the new web
---++ Hierarchical Webs
You can only create hierarchical webs (webs within webs) if the ={EnableHierarchicalWebs}= setting in [[%SCRIPTURLPATH{"configure"}%][configure]] is enabled. Hierarchical webs are currently %IF{"{EnableHierarchicalWebs}" then="enabled." else="disabled. Without this setting, TWiki will only allow a single level of hierarchy. With it, you can use multiple levels, like a directory tree, i.e. webs within webs."}%
__%T% Note:__ You might not need hierarchical webs. TWiki topics already have a parent/child relationship within a web, which is shown in the breadcrumb. Try to keep the number of webs to a minimum in order to keep search and cross-referencing simple. TWiki runs faster if hierarchical webs are disabled.
You can create hierarchical webs via the _Adding a New Web_ form above, by using a slash- or dot-separated path name which is based on an existing web name in the _Name of new web:_ field.
*Example:*
To create a sub-web named =Bar= inside a web named =Foo=, use =Foo/Bar= or =Foo.Bar= as the new web name in the form above.
---+++ Sub-web Preferences are Inherited
The preferences of a sub-web are inherited from the parent web and overridden locally. Preferences are ultimately inherited from the [[%SYSTEMWEB%.TWikiPreferences]] topic.
*Example Preference Inheritance for =Sandbox/TestWeb/SubWeb.SubWebTopic= topic:*
1. =%SYSTEMWEB%.TWikiPreferences= site-wide preferences
2. =Sandbox.%WEBPREFSTOPIC%= inherits from and overrides settings in =%SYSTEMWEB%.TWikiPreferences=
3. =Sandbox/TestWeb.%WEBPREFSTOPIC%= inherits from and overrides settings in =Sandbox.%WEBPREFSTOPIC%=
4. =Sandbox/TestWeb/SubWeb.%WEBPREFSTOPIC%= inherits from and overrides settings in =Sandbox/TestWeb.%WEBPREFSTOPIC%=
5. =Sandbox/TestWeb/SubWeb.SubWebTopic= inherits from and overrides settings in =Sandbox/TestWeb/SubWeb.%WEBPREFSTOPIC%=
---+++ Navigation
The PatternSkin indicates sub-webs by indenting them in the sidebar relative to their level in the hierarchy. The SiteMap shows a list of webs; sub-webs are separated by dots, such as =Web.SubWeb.SubSubWeb=.
#RenameWeb
---++ Renaming or Deleting a Web
Rename a web via the Tools section in each web's %WEBPREFSTOPIC% topic. You may delete a web by moving it into a Trash web.
---+++ Permissions
You may only rename a web if you have the following permissions
* You must be allowed to rename and changes topics in the web you want to rename
* You must be allowed to rename topics in the parent web of the web you want to rename
* If the web is a root web (i.e. it has no parent web) then you must have permission to both create and rename root webs. These permissions are controlled by the ALLOWROOTCHANGE preference, which can be set in [[%USERSWEB%.TWikiPreferences]].
* If you move the web to another parent web you must be allowed to create and change topics in the new parent web.
When you rename a web TWiki will try and update all links that refer to the old web. You should note that links only get updated in topics that you are allowed to edit. If you use access rights in the TWiki installation it is generally best to let an administrator rename webs to avoid too many broken links.
---+++ Edit Conflicts
If anyone is editing a topic which requires updating, or which lives in the web being renamed, a second confirmation screen will come up which will indicate which topics are still locked for edit. You may continue to hit the refresh button until an edit lease is obtained for each topic which requires updating (the "Refresh" button will change to "Submit"), or hit "Cancel", which will cancel your edit lease on all affected topics.
---+++ Renaming the %SYSTEMWEB% or %USERSWEB% webs
Although technically possible, it is strongly advised __not__ to rename the %SYSTEMWEB% and %USERSWEB% webs. It complicates upgrades, and some extensions may make assumptions on the names of those system webs. For this reason, the rename web link is disabled in the %WEBPREFSTOPIC% topic in those webs.
__%H% Suggestion:__ Create a web that is the entry point for your TWiki, and change the link of the upper left site logo to that web. Do that with a WIKILOGOURL setting in [[%LOCALSITEPREFS%]].
If you want to rename the %SYSTEMWEB% or %USERSWEB% webs anyway:
* Physically move the webs below =twiki/data= and =twiki/pub= on the shell level.
* Change the ={SystemWebName}=, ={UsersWebName}= and/or ={LocalSitePreferences}= settings in the configuration using the [[%SCRIPTURL{configure}%][configure]] interface.
