CopyContrib

Copies webs, topics, attachments, or part of them

This extension can be used to copy topics and webs. It allows to select which parts of an item is to copied.

Typical use cases are:

1. duplicate topic assets: copy attachments, comments or preference settings to another existing topic
2. deploy wiki applications: copy a selection of topics to a target web
3. workflow scenarios: separate work on a draft topic from its last approved version by creating a copy first and copy the finished draft over as a newly approved version
4. versioned webs: create a new web for each version of a product
5. merge webs: create a new web by copying a list of webs to the new web
6. publish content: from a closed quality-managed authors-only area to a public read-only web

Usage

The work horse for all operation modes is a single service script called copy. It takes a mode parameter for which a copy agent is created to perform the actual operation. The basic skeleton for a form to call the copy service looks like this:

<form action="%SCRIPTURLPATH{"copy"}%/%WEB%/%TOPIC%" method="post">
  <input type="hidden" name="mode" value="topic" />
  <input type="hidden" name="includepart" value="fields" />
  <input type="hidden" name="includepart" value="form" />

  <input type="text" name="destination" size="80" />

  <!-- more parameters -->

  <input type="submit" />
</form>
