Part II. Phased Implementation Plan for DMAC- Task 0: Characterize the need for real-time data.º Category: The mode in which real-time data should be received has not been clearly articulated.A careful examination of the issues related to this must be undertaken. Such anexamination would include the number of sites that will want access to real time data, thenumber of originating data sites, the type of data that is required, etc.- Task 1: Adopt Unidata IDD as initial, provisional, fast-track transport solution.º Category: Unidata IDD is IOOS-pre-operational for operational, real-time delivery of formattedfiles to IOOS modeling sites. It is IOOS-pilot for format conversions of the data.- Task 2: DMAC evaluation and review of Unidata IDD, including data carry capacity, dataintegrity, and data delivery assurance.º Category: DMAC Governance Committee- Task 3: Evaluate the state of real-time data access to current and potential modeling operationalsites.º Work cooperatively to minimize unproductive duplication and maximize timely, reliableavailability of quality-controlled, real-time observations for modeling.º Category: Committee work- Task 4: Identify IOOS partner sites to serve as real-time data assembly and distributioncentersº Adopt the US GODAE server (collocated with USN FNMOC) as a provisional, pre-operationalIOOS real-time data assembly and distribution point (identification of other sites tofollow).º Category: IOOS Governance- Task 5: As needed, initiate complementary and/or alternative real-time delivery solutionsas R&D activities, Pilots, or Pre-operational solutions.º Category: DMAC Governance Committee- Task 6: Explore blended Push/Pull delivery in which data are pushed only to data assemblycenters. All others use Pull delivery (typically middleware, FTP, or HTTP transfers).º Category: Contract• Deliverables:• Estimated Resources:• Schedule:• Sequencing:• Partnerships: Modeling centers, data assembly centers3. Activity: Develop DMAC Middleware• Description: The middleware solution embodies four components: (1) the Ocean DataAccess Protocol (ODAP) – the format-neutral method of requesting and receiving data andmetadata over an Internet connection, (2) translating data from legacy data management systems(formatted files, RDBMS, etc.) into the ODAP, and (3) ingesting data from the ODAP into88
