        Data Distribution System to Other Data Distribution Systems: data provision
      Flow Description 
        Data provision provides the source material for a publish-subscribe or query-retrieval data distribution scheme. This is the 1 of the 1:N data distribution architecture. This flow is a super-flow; it does not define data elements but is inclusive of any flow implemented using publish-subscribe or query-retrieval methods.

              Solution Description 
        This solution is used within the U.S. and Australia.  It combines standards associated with Flow-Specific Data with those for C-C: NTCIP Messaging. The Flow-Specific Data standards include a placeholder for upper-layer standards necessary to complete a solution for a generic support information flow. Prior to implementation, specific upper-layer standards need to be identified to tailor the flow to meet the specific data exchange needs..  The C-C: NTCIP Messaging standards include lower-layer standards that support partially secure communications between two centres as commonly used in the US.
