I'd definitely be interested in working on notifications. We'd like clients to be able to know about events like the ones you suggest, plus: - new resource in collection I'm subscribed to - Access control change in resource I'm subscribed to - New version in VCR (similar to your update/last-modified event, perhaps equivalent) How do we proceed? lisa > -----Original Message----- > From: ietf-dav-versioning-request@w3.org > [mailto:ietf-dav-versioning-request@w3.org]On Behalf Of Jösh Cohen > Sent: Wednesday, August 29, 2001 12:26 PM > To: deltav@wegalink.de; ietf-dav-versioning@w3.org > Subject: Re: WebDAV Invalidation (Was Re: Allow: header and supported > methods) > > > While Im nervous about trying to boil the ocean > in the form of a 'general notifications protocol', Im > wondering what people think about including the ability > to subscribe to events on resources? > By this I mean, in short, being able to subscribe > to a resource, such that when things happen to it, > such as: > o property change > o update (last modified) > o invalidate > o lock expiration / lock override > o deleted > > a subscribed entity would receive a notification. > > There's been some relevant work here in the form of > an HTTP extension (SUBSCRIBE/NOTIFY methods) in the past > to deal with some of these issues.
