Abstract Model Workgroup

From Direct Project
Jump to navigation Jump to search

Our Goals

To create a formal abstract model that will:
  • Provide a common set of terminology on which other workgroups may base their discussions,
  • Provide a common frame of reference for expected actors and transactions in an NHIN Direct message exchange,
  • Enhance understanding of NHIN Direct by new participants.

What We've Created

The NHIN Direct Abstract Model and associated examples are the primary output of this group. Although consensus will be reached at interim points, the abstract model is expected to be refined and altered as decisions are made in other workgroups around security, interoperability, etc...

What We're Still Working On

The Abstract Model Workgroup will continue to iterate over the Abstract Model as issues or refinements are suggested; however, the model is currently in a fairly stable state.

Our Schedule
