A big +1 Streamed content is a big deal on the Web and we should address it. However, dunno exactly, yet, what the implications are (gotta dig deeper, that is ;) Cheers, Michael -- Dr. Michael Hausenblas LiDRC - Linked Data Research Centre DERI - Digital Enterprise Research Institute NUIG - National University of Ireland, Galway Ireland, Europe Tel. +353 91 495730 http://linkeddata.deri.ie/ http://sw-app.org/about.html > From: Silvia Pfeiffer <silviapfeiffer1@gmail.com> > Date: Sun, 26 Jul 2009 22:55:45 +1000 > To: Media Fragment <public-media-fragment@w3.org> > Subject: feedback on use cases and requirements > Resent-From: Media Fragment <public-media-fragment@w3.org> > Resent-Date: Sun, 26 Jul 2009 12:56:41 +0000 > > Hi all, > > I have had some discussions with a company that provides live > streaming solutions about our media fragment addressing approaches. > They are keen to make use of the specification for certain use cases > that they are after. > > > 1. A first use case that was provided is the following: > A URL to a live video stream may look as follows > http://www.example.com/video.ogv .
