All existing subcommunity entry information will be replaced with the new data. To avoid deleting all existing data, retrieve any data you want to retain first, and send it back with this request. For example, if you want to add a new tag to a subcommunity entry, retrieve the existing tags, and send them all back with the new tag in the update request. See Retrieving a subcommunity
for more information.
Provide a subcommunity Atom entry document. A subcommunity is the same as a community entry, but contains a rel="http://www.ibm.com/xmlns/prod/sn/parentcommunity" <link> element. The content type of the Atom entry document must be application/atom+xml.
