Recommended Sequence

Changed:
<
<		There no absolute need for meta data variables to be in a specific order, however, it does for the following reasons:
  • Keep (form) fields in the order they are defined
  • Allow diff command to give output in a logically sensible order

These could be done in other ways, but this adds complexity

  • Order fields - definition could be read on each rendering (expensive)
  • Diff - render data before doing diff, has something to offer, but not likely to be available for next TWiki release
>
>		There is no absolute need for Meta Data variables to be listed in a specific order within a topic, but it makes sense to do so a couple of good reasons:

  • form fields remain in the order they are defined
  • the diff function output appears in a logical order

The recommended sequence is:

 
Deleted:
<
<		So the order is:
 
  • TOPICINFO
Changed:
<
<
  • text of topic
  • TOPICMOVED - optional
  • TOPICPARENT - optional
  • FILEATTACHMENT - 0 or more entries
  • FORM - optional
  • FIELD - 0 or more entries (FORM required)

  • text of topic

Known Issues

Changed:
<
<		There is currently no support for meta data for Plugins. However, the format is readily extendable and the Meta.pm code that supports the format needs only minor alteration.
