Part II. Phased Implementation Plan for DMAClegacy and new client applications. The system will be capable of restricting data delivery basedon data volume to be delivered. These must be changeable at the discretion of the DT team orDMAC Governance.• Milestone 1: Determine the breadth of data management solutions in use by IOOS data suppliers,which must be supported by the middleware.- Task 1: Survey the IOOS participants to determine the current data management solutionsin usage, the file formats and data management systems that must be addressed by the middleware,and the particular data sets which depend upon each management approach. Evaluatethe subsetting needs that attend each data management system.º Category: contract- Task 2: Prioritize the server-side requirements based on IOOS theme priorities and criticaldata streams.º Category: DMAC Governance Committee- Task 3: Initiate development of server-side solutions based upon prioritiesº Sequencing: must follow adoption of initial transport protocolº Category: contract• Milestone 2: Determine the breadth of legacy and new client applications that should besupported. Similarly survey and prioritize requirements for delivery of formatted subsets to users.Priorities should reflect the seven IOOS themes- Task 1: Survey user groups (and potential ocean information product suppliers) to accessapplication and formatted file needs.º Category: IOOS User Outreach Committee activity- Task 2: Prioritize the client-side requirements based on IOOS theme priorities and criticaldata streams.º Category: DMAC Governance Committee- Task 3: Initiate development of application solutions and downloadable formats basedupon priorities.º Sequencing: must follow adoption of initial transport protocolº Category: contract• Milestone 3: Determine the specification for the ODAP.- Fast-track note: An effective implementation of the DMAC middleware component issingularly important to the ability to begin the integration of IOOS, as it allows data suppliersand users to bypass traditional barriers of file format, size, and locality. If a suitable candidateis available, it will significantly advance the IOOS to implement a fast-track solution to thiscomponent. The Plan must include procedures to evaluate the effectiveness of the solutionadopted and either make adjustments to it or abandon it, if it proves unsuitable.- Task 1: Adopt OPeNDAP as initial, provisional fast-track transport solution.89
