When submitting artifacts or methodology to the HL7 SAIF IG the ISD will develop this content in compliance with the principles and language of the SAIF CD.

  1. I can't find conference call details in the conference call center.. where and when do we meet?

  2. John Moehrke The ISD actually does not hold regular calls. Instead it holds as needed weekly "decisions" that co-chairs are to vote on. 

    1. Then the above should say that... not explain that one should go to the "conference call center" only to find nothing there. Also I understood there is an expectation that there is a call on the second tuesday of the month... so we need clarity. I certainly am NOT looking for more useless calls. I like the 'on demand' plan. Just need clarity.
