RE: [XCON] Talking Points

["Brian Rosen" <br at brianrosen.net>]

User is a little bit of a special case here, because the protocol doesn't
actually provide a method to directly create one.  It indirectly creates
them by users responding to actions resulting from using dial out, dial
in/refer mechanisms.  In the end, however, a new user would be added to the
list of users, and would have some kind of index that would be used for, as
in the example, a user volume control.

A better example is the dial out list.  You explicitly add/delete an item on
that list.

You don't have to create the volume control entry explicitly; when a new
user is added, by the focus, it effectively adds a new volume control to the
volume control list.  So we don't need to AddListElement(Volume); it's done
implicitly.  You can immediately Set(Volume(user)) (ignore syntax)

I'm not sure I understand why you need to explicitly call out the list
data structure for the participant .... Isn't this self-described by the
data model?

AddListItem(Participant), DeleteListItem(Participant).  May need a
modify, but I don't think so

Brian - I guess this all depends on how you define a participant.  If
the participant has tied properties that might change during a
conference then a modify might be needed.

Using my verb/noun list:

    * Create Conference based on specified blueprint
Create(Conference)
    * Create Conference based on implied blueprint
Create(Conference)
    * Modify/Delete/Get Conference
Delete(Conference).  Maybe I need a get/modify but I don't think so
    * Add/Modify/Delete/Get User
AddListItem(Participant), DeleteListItem(Participant).  May need a
modify, but I don't think so
    * Modify User Roles
Is this AddListItem(AllowedRoles)?  I'd need a new noun for List
    * Add/Modify/Delete/Get Endpoint
I'm not sure exactly what this is, but may need another noun for
endpoint
    * Add/Modify/Delete/Get Endpoint Media I'm pretty sure this is not
xcon state
    * Add/Modify/Delete/Get Media Groups I'm pretty sure this is not
xcon state
    * Add/Modify/Delete Sidebar
Create(Sidebar), Delete(Sidebar) not sure you need a modify
   Generally I think you have a very simplistic create, and then use 
   set/get to change values in the object the create made for you
    * Add/Modify/Delete/Get Role
Need a noun, maybe Set(Role), but is this actually conference state?
    * Add User To Sidebar
AddListItem(Sidebar)
    * Delete User From Sidebar
DeleteListItem(Sidebar)
    * Move User Between Sidebars
Delete then add.  Doesn't have to be a transaction I think
    * Add/Modify/Delete/Get XML element
Set/Get(one of my list of nouns)
    * Set/Get/Delete XML attribute
Dunno what you mean
    * Get Templates
Aha, need a noun for set/get "focus"
    * Get Blueprints
Get(focus)
    * Get Active Conferences
Get(focus)

    * Cancel
Cancel what?
    * Ping
Ping on the conf control channel?  Some no-op
    * Options
Dunno what you mean
