Managing Webs

Adding, renaming and deleting webs are all web-based operations.

Overview

A TWikiSite is divided into webs; each one represents one subject, one area of collaboration. Administrators (in the TWikiAdminGroup) can add/rename/delete webs.

Choose Web Template

There are two methods used to create a new web. First you can use a specially designed TemplateWeb. This is an invisible web that begins with an underscore "_" character (for example _default). All topics in the template web will be copied into your new web.

The second method is to use an existing web as a template web. This may be useful if you already have a web that you like to use as a starting point. Only topics that have names beginning with Web... (like "WebHome", "WebNotify", etc.) are copied.

In either case you will want to be sure to verify that your new web has all the custom modifications that you desire.

Adding a New Web

Create a new web by filling out this form.
Note: Keep the number of webs to a minimum! It is not recommended to create a new web for each little project. You can organize content within a web using categories, TWikiForms and FormattedSearch. Cross-linking topics and search is easier if there are only a few larger webs.

Name of new web:		The name must start with an upper case letter, followed by upper or lower case letters or numbers. Specify a short name to avoid long URLs.
Based on web:	_default Main Sandbox TWiki	Select a TemplateWeb
Web color:		Enter a StandardColors code for the web
Description:	Enter a short description of the web. Write Web.TopicName instead of just TopicName if you include links. This will list the web in the SiteMap (leave field empty if you prefer not to update the directory.)
Use to...	Continue the sentence describing the intended use. This is also for the SiteMap
Exclude web from "search all":	No   Yes	Specify if you want to exclude the web from a "search all webs" search. Note that the SiteMap will not list the web if you select Yes.

Notes:

• Attachments will NOT get copied over along with their topics
• While creating the new web, TWiki will update the following variables in the WebPreferences: WEBBGCOLOR, SITEMAPLIST, SITEMAPWHAT, SITEMAPUSETO and NOSEARCHALL. These variables are used to dynamically generate the SiteMap
• TWiki does not edit the TWiki.TWikiPreferences to update the WIKIWEBLIST. This must be done by hand

Renaming or Deleting a Web

Rename a web via the Tools section in each web's WebPreferences topic. You may delete a web by moving it into a Trash web.

Permissions

You may only rename a web if you have permissions to rename all the topics within that web, including any topics in that web's subwebs. You will also need permissions to update any topics containing references to that web.

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 webs in the distribution

If you plan to rename the Main web, remember that TWiki stores user and group topics in %MAINWEB%, which by default is Main (this is assigned in the site configuration). That means that every WikiName signature - Main.SomeUserName - points to it and would need updating (unless the variable, %MAINWEB%.SomeUserName, is used throughout). This potentially large change can be performed automatically with the renameweb function mentioned above, in the Main.WebPreferences topic.

If you want to rename the TWiki web, remember it is referred to by %TWIKIWEB% which is also defined by a configuration setting.

Hierarchical Webs

Hierarchical web support is enabled by turning on the {EnableHierarchicalWebs} setting in configure. Without this setting, TWiki will only allow a single level of hierarchy (webs). If you set this, you can use multiple levels, like a directory tree, i.e. webs within webs.

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.

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 subweb named Bar inside a web named Foo, use Foo/Bar or Foo.Bar as the new web name in the form above.

Subweb Preferences are Inherited

The preferences of a subweb are inherited from the parent web and overridden locally. Preferences are ultimately inherited from the TWiki.TWikiPreferences topic.

Example Preference Inheritance for Sandbox/TestWeb/SubWeb.SubWebTopic topic:

1. TWiki.TWikiPreferences site-wide preferences
2. Sandbox.WebPreferences inherits from and overrides settings in TWiki.TWikiPreferences
3. Sandbox/TestWeb.WebPreferences inherits from and overrides settings in Sandbox.WebPreferences
4. Sandbox/TestWeb/SubWeb.WebPreferences inherits from and overrides settings in Sandbox/TestWeb.WebPreferences
5. Sandbox/TestWeb/SubWeb.SubWebTopic inherits from and overrides settings in Sandbox/TestWeb/SubWeb.WebPreferences

Navigation

The Pattern skin (default) indicates Subwebs by indenting them in the sidebar relative to their level in the hierarchy.
