== TAB / SIG / MMT Framework ==
 * Top Layer - TAB - Technical ''Advisory ''Board
   * board appointed representatives of all SIG's and working groups.
   * primarily for road-map coordination, management visibility of work and deliverable progress, resourcing, priorities, etc.
   * coordination with collaborating external work-groups & potentially competing initiatives. More, wider cooperation is always possible and valuable, but pragmatically limited by need to focus on delivering on already agreed collaborations and initiatives.
 * Mid Layer - SME SIG's - Subject Matter Special Interest Groups
   * focussing on agreeing subject matter definitions and requirements for reference data,
   * authority on SME content and usage, reporting deliverables to TAB.
   * any appropriate deliverable format. PCA / JORD-supported sandboxes ideally / ultimately.
   * formation of new SME SIG's generally "ground-up" by groups discovering interest in creating new content.
   * SIG membership limited to members of participating membership organisations, except where TAB authorizes participation by valuable non-member contributors.
   * any non-SME-specific modelling and technology issues / questions routed to Technical SIG's
 * Bottom Layer - Technical SIG's - technical subjects common across all working SIG's.
   * Includes MMT SIG and Technology Architecture SIG
   * Core MMT Group within MMT SIG for '''''commitment '''''to formal expert review, and a deadlock-breaker group with decisive '''''authority '''''on otherwise incomplete technical agreements. Authority comes from main PCA board (and MoU's with collaborating boards) via the TAB appointment of the core and deadlock-breaker groups.
