Hello, We have discussed the recent comments on timing of the challenge. The final deadline (June) would be hard to push back because we already have confirmation that the workshop will be held at HPDC (yet to be told whether it will be on the 25th or 26th). However, it seems that the first phase deadline is the one people have most difficulty with, so we propose moving it back to 20th February. The timetable would then be: - First phase deadline: 2007 February 20 - Final deadline/workshop: 2007 June 25/26 Would this be better / adequate? Thanks, Simon, Juliana, Luc On 13/12/06, Bertram Ludaescher <ludaesch AT ucdavis.edu> wrote: > >>> On Wed, 13 Dec 2006 06:52:32 -0800 > >>> "Bertram Ludaescher" <ludaesch AT ↵ ucdavis.edu> wrote: > ... > BL> If we just dump our internal RWS and COMAD provenance records on ↵ the > BL> wiki site, however, it might not be useful for others (no effort ↵ was > BL> spent on making the format interoperable, e.g. as XML -- so it ↵ might > BL> be hard for PC-2 folks to do sth with it). > > I was just reminded about the fact that COMAD provenance info is > available in XML.
