---## Meta Data Rendering

Various meta data can be stored in topics - MetaDataDefinition

This is rendered using the %<nop>META% variable.  This is mostly used in the =view=, =preview= and =edit= scripts.

At present support is fairly basic:
  | *Variable usage:*   | *Comment:*  |
  | =%<nop>META{"form"}%= | Show form data, see [[TWikiDocumentation#Form_Templates][Form Templates]] |
  | =%<nop>META{"attachments"}%= | Show attachments, excluding hidden ones. Options: <br > \
    ==all="on"==: Show all attachments i.e. including hidden ones |
  | =%<nop>META{"moved"}%= | Details of any topic moves |
  | =%<nop>META{"parent"}%= | Show topic parent. Options: <br /> \
    ==dontrecurse="on"==: By default recurses up tree, this has some cost. <br /> \
    ==nowebhome="on"==: Suppress <nop>%HOMETOPIC%. <br /> \
    ==prefix="..."==: Prefix that goes before parents, but only if there are parents, default =""=. <br /> \
    ==suffix="..."==: Suffix, only appears if there are parents, default =""=. <br /> \
    ==separator="..."==: Separator between parents, default is =" &gt; "=. |

Possible future additions:
   * Rendering of form data to alternate formats e.g. bullet lists
   * Specify a template to be used for rendering
