  1. Project Definition

2.a.    Project Scope

Reaffirm HL7 Version 3 Standard: Transport Specifications - MLLP

2.b.   Project Need

The purpose of the MLLP Protocol (Minimum Lower Layer Protocol) is to provide both a minimalistic Open Systems Interconnection (OSI)-session layer framing protocol as well as a minimalistic reliable transport protocol. If security is an issue, additional protocols or technologies will have to be layered on top of MLLP to achieve these goals.

2.c.    Security Risks

Will this project produce executable(s), for example, schemas, transforms, style sheets, executable program, etc.  If so the project must review and document security risks.
