Part II. Phased Implementation Plan for DMACSection 1. Functional RequirementsThis document states high-level functional requirements for the Data Management and Communications(DMAC) Subsystem of the Integrated Ocean Observing System (IOOS). The intendeduse of this document is to supplement the white papers that describe the DMAC subsystems (PartIII of this document) and to rephrase the notions into the formal terminology of a requirementsspecification. The use of the term “requirements” is consistent with that used by the InternationalCouncil on Systems Engineering. 1 As described in the Handbook, this section also is intended “toestablish a database of baseline system requirements derived from the source, to serve as a foundationfor later refinement and/or revision by subsequent functions in the Systems Engineering processand for a non-ambiguous and traceable flow down of source requirements to the system segments.”2 This section includes requirements of the following types:• Program requirements• Mission requirements• Customer specified constraints• Functional requirements• System requirements• Interface, environmental, and non-functional requirements• Unclear issues discovered in the requirements analysis processThis section is written at a level that primarily addresses mission and customer requirements, alongwith high-level functional and system requirements. It is intended that this section serve as an assetto be used in subsequent engineering efforts to articulate the detailed system and interface requirementsthat are required to develop a DMAC.GENERAL REQUIREMENTS1. IOOS DMAC Vision1.1. The DMAC Subsystem of the IOOS will knit together the distributed components of IOOSinto a nationwide whole that functions as a unified component within the international GOOSframework. The vision for the DMAC Subsystem is not limited to the ingesting and archivingof observations; it includes the data and communications components needed to move dataamong systems and users in a distributed environment. The DMAC Subsystem will be requiredto link observations collected from a broad range of platforms: buoys, drifters, autonomousvehicles, ships, aircraft, satellites, and cabled instruments on the sea floor.
