Hi all,

  As mentioned in the CDNI session this morning, among the other editorial changes in this version of the draft, there were two changes that we wanted to make the wg aware of:

  1. We removed the sid property from the Grouping metadata object.
     Grouping contained ccid and sid.
     The intent of ccid is that the CSP/uCDN generates the ccid to group assets together, and the uCDN provides ccid to the dCDN so that it can use it to, e.g., aggregate logs.
     The sid, however, is a field that is generated by the dCDN and placed into the log file; it is not a value that is provided by the uCDN to the dCDN.  The only value of sid could be to enable sid generation by the the dCDN, and we and the LI authors did not see a point in having an enable bit, so we removed it.

  2. We removed the CredentialAuth simple type.
     CredentialAuth had a simple username/password.  It was really meant to just be an example of an Auth object (until we get the URI signing Auth object), but we didn't think it was really useful.  For delivery auth, the uCDN would never distribute every possible username/password combination to the dCDN.  For acquisition auth, username/password did not seem very useful, and it can be embedded into the acquisition UR.  Given these, we removed CredentialAuth to reduce clutter.

  If anyone disagrees with these decisions please let us know.

thanx!

> Abstract:
>    The Content Delivery Networks Interconnection (CDNI) metadata
>    interface enables interconnected Content Delivery Networks (CDNs) to
>    exchange content distribution metadata in order to enable content
>    acquisition and delivery.  The CDNI metadata associated with a piece
>    of content provides a downstream CDN with sufficient information for
>    the downstream CDN to service content requests on behalf of an
>    upstream CDN.  This document describes both a base set of CDNI
>    metadata and the protocol for exchanging that metadata.
