There might be a problem when it comes to sharing: when
an ItemCollection is fetched from the server, the sharing code would
have to morph that into a SidebarCollection, and I'm not sure that's
the way to go.
Talked with Morgan about his comment - "not to worry," I said
This mechanism supplements what is already there.
I decided to instead go with calling it SidebarItem instead of
SidebarCollection, that way your type can derive itself from
ItemCollection if that's what you are, otherwise you can derive from a
view to create your own UI.

So I've been working on a system for chandler
extensions to "plug in" to the sidebar and I'm curious what people
think of my scheme. Here's how it works:
* I added a new Kind, <SidebarCollection> that derives
directly from
<ItemCollection>
* I added a rule to the <ItemCollection
itsName="sidebarItemCollection"> - see below....
<contentModel:ItemCollection itsName="sidebarItemCollection">
<_inclusions itemref="content:allItemCollection"/>
<_inclusions itemref="content:inItemCollection"/>
<_inclusions itemref="content:outItemCollection"/>
<_inclusions itemref="content:CalendarView"/>
/ *<!-- this allows extensions to hook into the sidebar -->
<_rule value="for i inevery
'//parcels/osaf/framework/blocks/SidebarCollection' where True"/>*
/ </contentModel:ItemCollection>
* For ZaoBao, what I was able to do was make its type derive from
<SidebarCollection> as follows:
<Kind itsName="RSSChannel">
<superKinds itemref="content:ContentItem"/>
/* <superKinds itemref="docSchema:SidebarCollection"/>*/
...
Now, every time ZaoBao makes an RSSChannel, that object is also a
SidebarCollection. the RSS Channel need only populate itself as though
it were an ItemCollection, and its items will appear in the summary
view.
Now I don't know enough about queries to know if this is really a smart
way of searching the repository for items that want to hook into the
UI... is there a better way than creating a new Kind?
