Dear PC members,
 
Earlier this year we had some discussion about the number of sessions available at OGF20.  I've looked at recent GGF events for comparison.  These figures are approximate because I had to guess which topics some of the sessions came under. 
 
Summary - we currently have more sessions allocated for group meetings than GGF17-OGF19.   We have slightly fewer enterprise sessions (not including the Grids Mean Business track).  We have the same number of E-Science sessions as GGF17, which is less than GGF18 and OGF19.
 
GGF17 - colocated with GridWorld Japan.
3 days, 5-7 parallel sessions
Keynotes: 2
Other invited talks: 2
Enterprise: 4
E-science: 16
Groups: 55
 
GGF18 - colocated with GridWorld USA and GlobusWorld
4 days, 8-10 parallel sessions
Keynotes - 1
Enterprise - 8
E-Science - 28
Groups - 57
 
OGF19
5 days, 6-7 parallel sessions
Keynotes - 0
Enterprise - 9
E-Science - 20
Developer - 15
Groups - 65
 
OGF20 - draft programme, not including EGEE sessions
3 days (+2 for groups), 7-9 parallel sessions
Keynotes - 1
Other invited talks - 2 (EGEE/OGF)
Enterprise - 6
E-Science - 16
Developer - 8
Grids Mean Business - 7
Groups - 72 (including 16 on Thu/Fri)
 
Previous keynotes have been one hour long.  I need to adjust the OGF20 programme to make the keynote this length.
