(FYI) -------- Original Message -------- Subject: Protocol Action: 'Collection Synchronization for WebDAV' to Proposed Standard (draft-daboo-webdav-sync-08.txt) Date: Mon, 30 Jan 2012 16:13:25 -0800 From: The IESG <iesg-secretary@ietf.org> To: IETF-Announce <ietf-announce@ietf.org> CC: RFC Editor <rfc-editor@rfc-editor.org> The IESG has approved the following document: - 'Collection Synchronization for WebDAV' (draft-daboo-webdav-sync-08.txt) as a Proposed Standard This document has been reviewed in the IETF but is not the product of an IETF Working Group. The IESG contact person is Peter Saint-Andre. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-daboo-webdav-sync/ Technical Summary This specification defines an extension to WebDAV that allows efficient synchronization of the contents of a WebDAV collection. WebDAV (RFC 4918) defines the concept of 'collections' which are hierarchical groupings of WebDAV resources on an HTTP server. Collections can be of arbitrary size and depth (i.e., collections within collections). WebDAV clients that cache resource content need a way to synchronize that data with the server (i.e., detect what has changed and update their cache). This can currently be done using a WebDAV PROPFIND request on a collection to list all members of a collection along with their DAV:getetag property values, which allows the client to determine which were changed, added or deleted. However, this does not scale well to large collections as the XML response to the PROPFIND request will grow with the collection size. This specification defines a new WebDAV report that results in the server returning to the client only information about those member URIs that were added or deleted, or whose mapped resources were changed, since a previous execution of the report on the collection. Additionally, a new property is added to collection resources that is used to convey a "synchronization token" that is guaranteed to change when the collection's member URIs or their mapped resources have changed. Working Group Summary This document is not the product of a working group. However, it has been discussed on the w3c-dist-auth@w3.org and reviewed among implementers in the calendaring and scheduling community. Consensus was quite smooth. There was some slight controversy about whether servers should be allowed to return reports with a depth of infinity, but that issue was decided in the positive because some implementers have uses for such reporting. Document Quality There are several independent implementations (mostly email clients and calendaring applications). Personnel The Document Shepherd / Responsible Area Director is Peter Saint-Andre. _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
