Similar to how the <activity:object-type> blog entry is a specialization of the "article" object type, we may also want to add a "forum-topic" of "forum-post" or "forum-root" object-type to describe articles that are commentable in Forums. 

Brainstorm

A "forum-topic" <activity:object-type> could be a specialization of the "article" object type:

     http://activitystrea.ms/schema/1.0/forum-topic 

Examples

Services that have forums include:

• MySpace: http://wiki.developer.myspace.com/index.php?title=ActivityStream_Notes#Posting_a_Forum_Topic

   

  In their current implementation (as of 2009-08-30), MySpace uses a custom <activity:object-type> for forum posts

• phpBB: http://www.phpbb.com/
• Simple Machines Forum (SMF): http://www.simplemachines.org/
