---## Meta Data Rendering
Various meta data can be stored in topics - MetaDataDefinition
This is rendered using the %META% variable. This is mostly used in the =view=, =preview= and =edit= scripts.
At present support is fairly basic:
| *Variable usage:* | *Comment:* |
| =%META{"form"}%= | Show form data, see [[TWikiDocumentation#Form_Templates][Form Templates]] |
| =%META{"attachments"}%= | Show attachments, excluding hidden ones. Options:
\
==all="on"==: Show all attachments i.e. including hidden ones |
| =%META{"moved"}%= | Details of any topic moves |
| =%META{"parent"}%= | Show topic parent. Options:
\
==dontrecurse="on"==: By default recurses up tree, this has some cost.
\
==nowebhome="on"==: Suppress %HOMETOPIC%.
\
==prefix="..."==: Prefix that goes before parents, but only if there are parents, default =""=.
\
==suffix="..."==: Suffix, only appears if there are parents, default =""=.
\
==separator="..."==: Separator between parents, default is =" > "=. |
Possible future additions:
* Rendering of form data to alternate formats e.g. bullet lists
* Specify a template to be used for rendering
