+== Wiki Edit Workflow Proposal ==
+
+As wiki SPAM gets worse, as people start using trac for more critical
+projects, and as I develop the plugin that implements my evil master
+plan for world domination, there's going to need to be a lightweight,
+trac-ish way of allowing plugins to do page edit workflow.  I have
+that need right now.  I want to tackle this, I plan to post the result
+on trac-hacks.org, but before I spend a lot of time going down a
+development path, I think I should get some advice as to which path I
+should take; it's looking more and more like trac itself will need to
+be patched, and I'd prefer to do this in a way that the patch will
+likely be accepted into mainstream.
+
+There appear to be (at least) two parts to this problem:  (1) The
+default viewable version of a wiki page needs to be selectable via an
+extension point, not hardcoded as "highest version number", and (2)
+the version of the page which a user edits when they hit "Edit This
+Page" needs to be configurable, rather than "most recent".
+
+I'm starting to think that (1) is going to require a change to the
+!WikiPage class, and (2) a change to !WikiModule.  
+
+In !WikiPage, if version number is None then the default action is
+determined by the ORDER BY sorting in a SELECT statement.  I see three
+choices here:
+
+ * patch !WikiPage to add an IWikiPageVersionSelector extension point
+      (called before SELECT); this helps anyone implementing workflow
+ * patch !WikiModule to add an IWikiPageProvider extension point; then
+      !WikiPage implements IWikiPageProvider; this helps anyone using
+      alternate wiki page storage and/or workflow 
+ * don't patch the code; just have my own plugin do the job via
+      overriding and subclassing !WikiModule, reassigning the 'WikiPage'
+      symbol at runtime, and/or other guerilla tactics; this helps nobody
+      other than myself
+
+In !WikiModule, right now an edit is hardcoded as "latest version" in
+process_request.  But you'd actually want the "Edit This Page" button
+to edit the version you're looking at, or maybe the currently elected
+version, not the latest version.  This probably needs a trac.ini
+configuration item to control it -- either another patch or another
+override.
+
+Does anyone have any preference as to which of these routes I take?  Feel free to edit this page...
