This idea started as an XPATH extension of the page link syntax of JSPWiki.
%%(border-left:4px solid silver; padding-left: 1.5em; margin-top:-1em; margin-bottom:1em;)
It has been extended with new ideas of page organising concepts.

The extended [[page link] syntax would also provide support to some further extensions of JSPWiki for more advanced ''organisational concepts'' such as
[WikiFarms|IdeaWikiLinksThroughXPATHIncludingSubPagesSupport#WikiFarm],
[WikiWebs|IdeaWikiLinksThroughXPATHIncludingSubPagesSupport#WikiWeb],
[WikiSubPages|IdeaWikiLinksThroughXPATHIncludingSubPagesSupport#WikiSubPages],
[WikiCategories|IdeaWikiLinksThroughXPATHIncludingSubPagesSupport#WikiCategories] and
[WikiTags|IdeaWikiLinksThroughXPATHIncludingSubPagesSupport#WikiTags].

!! ~WikiFarm
URL Syntax: {{{http://baseURL/...}}}
A ''~WikiFarm'' is a grouping of ~WikiWebs, running on the same wiki engine, behind the same ''baseURL''.
It provides for a common administration platform for a set of wikis.
All ~WikiWebs of a ~WikiFarm share the same ''user database'' and ''authentication'' policy.
The ~WikiFarm ''~SiteMap'' page provides an overview of all its ~WikiWebs.
{{{
[/w:wikiwebs] => renders a list of all WikiWebs' homepages in this WikiFarm
}}}
A ~WikiFarm provides overall administrative settings for properties such as:\\
''
baseURL, encoding, searchProvider, plugin.*, interWikiRef.* , rss.*, log4j.*
authorizer, userdatabase.*, groupManager, aclManager,
(new) defaultwikiweb
''
!! ~WikiWeb
URL Syntax: {{{http://baseURL/wikiwebnamespace:wikipagename}}}
A ~WikiWeb allows ~WikiPages to be grouped into separate namespaces.
This is especially useful when organising large chunks of information.
It also improves ease of administration. \\
However, separate namespaces may also decrease usability
as users must remember the ~WikiWeb name prior to the ~WikiPage name.
Preferably, the name of the current ~WikiWeb should always be visible in the GUI.
The ''current ~WikiWeb'' defines the scope of several wiki functions such as
[PageIndex], [RecentChanges], [UnusedPages], [UndefinedPages] and [FindPage].
An extra ''wiki-web'' option is to be added to the [FindPage] (and other plugins)
to allow searches in other sibling ~WikiWebs.
A ~WikiWeb may want to provide its own global pages such as
[LeftMenu], [LeftMenuFooter], [CopyrightNotice], [EditPageHelp], etc.. [3]
A ~WikiWeb may specify a dedicated location of its page repository and have a dedicated security policy.
A ~WikiWeb provides administrative settings via a GUI for properties such as:\\
''
%%strike frontPage%% homePage, templateDir, translatorReader.*, pageProvider, attachmentProvider, diffProvider,
(new) wikiWebNamespace, wikiWebSkin, wikiWebSecurityPolicy
''
Possibly, these properties could take another prefix iso {{jspwiki.}}
{{{
jspwiki.pageProvider=... => default pageProvider
zoo.pageProvider=... => pageProvider for the 'zoo' WikiWeb
}}}
Example
{{{
[zoo:] => links to the home page of zoo:
[zoo:Main] => link to the top Main page of zoo:
[zoo:*//Main] => links to all Main pages of zoo:
[Main] => links to zoo:Main when zoo: is the current wiki-web
}}}
%%(background:ff9;)
Q. Is the term ''~WikiWeb'' clear enough. Other suggestions: ''wiki-site'', ... ?
%%
!! ~WikiSubPages
URL Syntax: {{{http://baseURL/wikiwebnamespace:wikiparentpage/wikisubpage/wikisubsubpage}}}
~WikiPages can act as a container for other ~WikiSubPages as well as attachments.
Containment implies that e.g. renaming or deleting a ''parent'' ~WikiPage
also impacts all its child pages and attachments.
~WikiSubPages inherit the ACLs of their ancestor pages. Child pages can add (=restrict) ACLs
to those of the ancestors but never relax them. (parental control ;-)
Example
{{{
[Birds/Stork] => child pages use / as delimitter
[/Zoo/Birds/Stork] => absolute link
(start with / to denote the root of the current WikiWeb)
}}}
See also [Greedy Page Links|IdeaWikiLinksThroughXPATHIncludingSubPagesSupport#GreedyPageLinks] to keep your links short and backward compatibile with the current JSPWiki links.
!! More organising concepts
While ~WikiFarms, ~WikiWebs and ~WikiSubPages implement pure hierarchical organising concepts.
More rich grouping concepts are possible through
[WikiCategories|IdeaWikiLinksThroughXPATHIncludingSubPagesSupport#WikiCategories] and
[WikiTags|IdeaWikiLinksThroughXPATHIncludingSubPagesSupport#WikiTags].
! ~WikiCategories
~WikiPages can be ''categorised'' into one or more ~WikiCategories. See also [WikiCategory]
In order to mark a page for inclusion in a special category, just link it to the ''category page''.
Category links can not be distinguished from ordinary page links.
Typically the categorised pages link back to the category pages via ''Back To...'' or ''More Info...'' or ''See also ...'' links.
The category page may contain a textual description of the grouping concept.
It may use the [[{ReferredPagesPlugin}] to automatically list all categorised pages.
%%(background:ff9;)
Q. Can a category page categorise pages of multiple ~WikiWebs ? I would tend to say yes,
although the [[{ReferredPagesPlugin}] would need some extra param to search for links
outside the current ~WikiWeb.
%%
! ~WikiTags
~WikiPages can be tagged with one or more ~WikiTags.
In order to mark a page with a tag, you will add some ''metadata'' to the page.
Typically, GUI support is available for easy page tagging
(select a tag from the existing set of tags of the current ~WikiWeb)
and to facilitate page searches based on certains tags.
Example:
{{{
[/w:tags/*] =>list all tags in this WikiWeb
[*[@tag='food']] =>list all pages tagged with 'food'
}}}
!! Greedy Page Links
The concept of ''greedy page links'' will keep your page links short and provide backward compatibility
with the current style of page-linking.
When resolving a [[page-link], the wiki-engine will first try to match ''any'' of the
children of the ''current page''.
When no match is found, the wiki-engine will continue its search from the root of the ''current ~WikiWeb''.
Use XPATH expressions to target more specific sets of pages. [4]
With the ''greedy page link alghorithm'', a single [[page-link] can now result in one or more clickable page links.
By default, the generated set of links are separated with a space. See [Formatting Wiki Links|IdeaWikiLinksThroughXPATHIncludingSubPagesSupport#FormattingWikiLinks] to change this formatting.
Example of the ''greedy'' page-link algorithm :
|| Current Page || Wiki markup... || Links to...
| /Zoo | [[Food] | /Zoo/Birds/flamingo/Food\\/Zoo/Birds/Stork/Food\\/Zoo/Birds/Stork/Summer/Food
| /Zoo/Birds | [[Food] | /Zoo/Birds/flamingo/Food\\/Zoo/Birds/Stork/Food\\/Zoo/Birds/Stork/Summer/Food
| /Zoo/Birds/Stork | [[Food] | /Zoo/Birds/Stork/Food\\/Zoo/Birds/Stork/Summer/Food
| /Zoo/Birds/Stork/Summer | [[Food] | /Zoo/Birds/Stork/Summer/Food
| /Zoo/Birds | [[Main] | /Main (the [[Birds] has no ''Main'' page children)
Example of XPATH expresssions :
|| Current Page || Wiki markup... || Links to...
| /Zoo/Birds/Stork | [[Summer/Food] | /Zoo/Birds/Stork/Summer/Food
| /Zoo/Birds/Stork | [[./Food] | /Zoo/Birds/Stork/Food
| /Zoo/Birds/Stork | [[.//Food] | /Zoo/Birds/Stork/Food\\/Zoo/Birds/Stork/Summer/Food
| /Zoo/Birds/Stork/Summer | [[../Food] | /Zoo/Birds/Stork/Food
| /Zoo/Birds/Stork/Sumer | [[..//Food] | /Zoo/Birds/Stork/Food\\/Zoo/Birds/Stork/Summer/Food
| /Zoo/Birds/Stork | [[../*/Food] | /Zoo/Birds/flamingo/Food\\/Zoo/Birds/Stork/Food
| any page | [[/Zoo/Birds] | /Zoo/Birds
| any page | [[/Zoo/Birds/*/Food] | /Zoo/Birds/flamingo/Food\\/Zoo/Birds/Stork/Food
%%(background:ff9;)
Q. What is the default format of a link ?
Is it the absolute path, such as {{/Zoo/Birds/Stork/Summer/Food}}.
Or the relative (and shorter) path, such as {{Stork/Summer/Food}} or {{./Stork/Summer/Food}} ?

[#2] Inspired by lots of stuff on the jspwiki mailing list, also on [http://twiki.org/cgi-bin/view/Codev/OrganizingPrinciples]
[#3] ~WikiWebs may define they own global pages suchs as [[LeftMenu] etc.
By default, a ~WikiWeb will ''inherit'' these pages from the default ~WikiWeb at creation.\\
Example contents of [[LeftMenu] of a newly created ~WikiWeb:
{{{
[{InsertPage page='<default-wiki-web>:LeftMenu'}]
}}}
[#4] [The greedy page link|IdeaWikiLinksThroughXPATHIncludingSubPagesSupport#Greedy page link] algoritm actually executes following XPATH expressions:
* If not-empty, return {{[[.//pagename]}} : matches all subpages of the current page
* Otherwise return {{[[//pagename]}} : matches all subpages of the root page of the current ~WikiWeb
