Metadata Types
==============

This file serves as incomplete registry of metadata types used in
uwiki. This is only a short list, documentation of the types is elsewhere.

Basic
-----
Metadata used by uwiki internally

`schema`::
  Schema definitions for the utable parser (these define all other metadata)

`acl`::
  Access Control List for any object (path/file) on the wiki.

`metaacl`::
  Access Control List for metadata operations.

`sys`::
  Pointer to the uwiki sources which are in effect.

`type`::
  Type of a file.

`source`::
  List if source files upon which this file depends.

`users`::
  directory containing user accounts.

`groups`::
  Group definitions, lists which users are in a group

`roles`::
  Role definitions, map a set of permission to a rolename

`scm`::
  Defines which versioning system is in effect.


Default
-------
Metadata for plugins shipped with uwiki


Contributed
-----------
For plugins which are externally developed and contributed. Please
extend this list by yourself. Don't remove, change or conflict
existing entries.



Planned
-------
Yet unused but planned for future extensions.

`trail`::
  For distributed wikis (cehtehs plan)

`home`::
  For distributed wikis (cehtehs plan)

`subscribers`::
  subscriptions




Reserved
--------
Undocumented or names which shall be never taken for
metadata entries

`uwiki*`::
 '_uwiki' is the name of the uwiki installation itself we want to
 prevent namespace clashes here, so anything starting with '_uwiki*'
 gives us a nice namespace in the docroot which can not be overridden
 by normal uwiki actions.

`_*`::
 names starting with a double underscore are reserved and unused for now.
