This draft is a work item of the Centralized Conferencing Working Group of the IETF. Title : Centralized Conferencing Manipulation Protocol Author(s) : M. Barnes, et al. Filename : draft-ietf-xcon-ccmp-02.txt Pages : 83 Date : 2009-03-09 The Centralized Conferencing Manipulation Protocol (CCMP) can create, retrieve, change and delete objects describing a centralized conference, such as state and capabilities of the conference, participants, and their roles. The conference information is contained in XML documents and fragments conforming to the centralized conferencing data model schema. CCMP is a state-less client-server protocol based on a request/response model. Conferencing clients send requests to conference servers, which respond to the client with the conference information. This document also discusses options for using existing notification protocols to inform conference client about the changes in the state of a conference during its entire lifetime.

Right now, there's nothing in the protocl that prevents user A from modifying the same conference object as user B. We could specify this is an implementation issue, but it seems this really is a core protocol requirement. Could we use floor control? Or, do we need something like WebDAV?=20 2) How do folks feel about having the schema snippets in the body of the document for each message? The benefit is that it does help you see the protocol structure, without having to search through the schema section. The con of course is that we need to fix two sections when there are changes. 3) Notification mechanism: do we need to define one or reuse existing? Right now, the default is specified as SIP. Is that sufficient for the initial version of the protocol? =20 Regards, Mary, Simon, Chris, Henning. -----Original Message----- From: xcon-bounces@ietf.org [mailto:xcon-bounces@ietf.org] On Behalf Of Internet-Drafts@ietf.org Sent: Monday, March 09, 2009 6:15 PM To: i-d-announce@ietf.org Cc: xcon@ietf.org Subject: [XCON] I-D Action:draft-ietf-xcon-ccmp-02.txt A New Internet-Draft is available from the on-line Internet-Drafts directories.

Protocol Overview Regarding locking, I think it is an implementation issue and common sense=20 should apply to the implementation. Typically, each CCMP operation would be=20 wrapped in a transaction on the CCMP server, this would guarantee data integrity.=20 Depending on the type of transaction mechanism, other requests wanting to modify=20 the same piece of data could overwrite it, once the other clients tx is committed or a 'StaleDataException' could be thrown. =09 An OPTIONS request is mentioned here but this is no longer part of CCMP. 6.1. Conference Object How in the schema can a conference/blueprints attributes be marked as unalterable?=20 Can this feature be expanded on in the draft? =09 7.1. Implementation Approach =09 It states that using the single HTTP verb to transport all CCMP messages provides the=20 capability to use CCMP with any chosen transport protocol. Is this a valid goal since this draft is only going to specify one transport mechanism? e.g. If I decide to wrap the messages in SOAP, then obviously my interface is non-standard.=20 =09 Personally I prefer SOAP, as it is geared towards a client/server implementation, has standards for security, encryption etc that could be used and there are a wide variety=20 of SOAP framework vendors out there... =09 Another thing about using generic messages for everything, is that depending on the message type some parameters are mandatory and some are not. This leads to more complex code when generating the messages... =09 7.2.3.2. confsRequest and confsResponse messages This request needs to be extended to allow search criteria to be passed to reduce the=20 number of conferences passes to client. All implememtations would require this so it might as well be part of the standard. =09 11. Managing notifications I dont think the SIP notifications mechanism is viable as it implies clients need both a HTTP stack and SIP stack at their disposal... Also, if a client is soley a booking client,=20 SIP should not come into the picture... =09 I think the notification format and transport mechanism needs to be defined similiarly to CCMP.=20 The SIP notification spec, to the best of my knowledge deals with call control, it has nothing for provisioning... What we really need is a notification specification that defines=20 the notifications for the complete conference model(including call control), a subscription mechanism=20 and details of transport mechanisms - SIP and some other protocol suitable for CCMP clients...

As per discussion in this mailing list and in the last IETF-74 meeting, the authors of the data model are proposing to add the following elements to the data model to explicit express cloning in the document. The elements we're planning to add are: - cloning-parent: When this element is present, it indicates that the conference object is a child of a parent conference. This element contains the conference object Identifier (XCON-URI) (different from the main XCON-URI) of the parent. - sidebar-parent; When this element is present, it indicates that the conference object represents a sidebar of another conference. This element contains the conference object Identifier (XCON-URI) (different from the main XCON-URI) of the parent. If nobody oppose to this modifications, we'll submit a new version of the document in brief.
