  • Hydra Meetings - SG, Partner and Developer Meetings
    • Sept 2012 and beyond:
      • Name should allow for mix of SG, partners and developer activities "Hydra Meeting"
      • Increased use of multi-track
      • Demos limit to twice per year at multi track meetings
      • Engineer Code Swap annual hackfest type meeting is desired (e.g. DIL or ScholarSphere into other IRs) Winter prior to Cod4Lib and DevConX would be good
      • An annual SG retreat to focus on strategic direction would be useful
    • Winter Meeting, Jan San Diego
      • Co-location with developers would allow combined dinner discussion
      • Time for SG to step aside and take a fresh look at Hydra direction
      • smaller number of people
      • visioning retreat
    • Overall
      • Winter Jan Developer & SG Retreat
      • Spring Mar LibDevConX & Hydra MultiTrack
      • Summer Hydra MultiTrack potentially co-located with OR?
      • Fall Hydra MultiTrack
