[With apologies for the massive cross-post... Do forward if I have missed anyone.] At OGF21 the JSDL-WG is planning a session on Activity schema requirements. JSDL addresses submission-time requirements but there is clearly a need for more. BES has taken a step forward in defining an ActivityDocument element that encapsulates a JSDL document; for use, for example, in the BES CreateActivity operation. In this session we'd like to explore current work and requirements and discuss how to move forward. So this session will be along the lines of an ad-hoc bof---presentations followed by discussion. We already have some presentations lined up but probably have room for more. If you would like to present at this session please send an email to either Steven McGough <asm@doc.ic.ac.uk> or myself. This session is scheduled for Wednesday (10/17) evening. http://www.ogf.org/gf/event_schedule/index.php?id=950 -- Andreas Savva Fujitsu Laboratories Ltd
