As you saw from the Internet-Drafts announcement, there is a new draft of the WebDAV Collections Protocol specification. Until Jim gets back to make it available from the WebDAV Web site, you will have to access it from the Internet Drafts directory: ftp://ftp.ietf.org/internet-drafts/draft-ietf-webdav-collection-protocol -01.txt The major changes made since the previous draft are: General Changes: 1. All dependencies on the Mandatory Extensions draft specification were removed. 2. Security Considerations have been added. 3. i18n Considerations have been added. 4. Status codes have been added. 5. Examples have been added. Referencing: 1. The MKREF method is defined for creating a referential resource. 2. Strong references are not supported in the current protocol, but headers and properties are defined to allow future extension to support strong references: Ref-Integrity with "Weak" and DAV:refintegrity with weak. 3. Definitions of direct / indirect references have been added. This spec supports only indirect references, but provides hooks for future support for direct references: Ref-Integrity, refintegrity, Pass-Through, passthrough, DELREF. 4. Discussion of GET, HEAD, POST, PUT has been revised to insure that plain HTTP clients can make use of WebDAV referential resources. Ordering: 1. To improve scaleability, the DAV:ordering property has been removed. Clients use the Position header to set / modify a member's position in the collection ordering. 2. A new ORDERPATCH method is defined for changing a collection member's position in the collection ordering. 3. DAV:orderingtype is now a separate, editable property. Clients edit this property to change a collection from unordered to ordered or vice versa, or to change the ordering semantics of a collection. 4. An Ordered header is defined for use with MKCOL to specify that a collection is to be ordered. Its value is either a URI identifying the semantics of the ordering, or "DAV:arbitrary" for unordered collections. 5. The value "At" <index> has been removed from the Position header. Judith A.
