Transition to Operations Strategy

Releases are the increments of the CI system in the operational environment. The CI will be rolled out in five increments (releases).

Configuration Items are the primary deliverables of the OOI Cyberinfrastructure system to the sponsor (COL/NSF). They will be commissioned and acceptance tested. CI commissioning only formally occurs after Releases 3 and 5.

Configuration Items

CI deliverable configuration items include (see Table 2.3.6.1-1).

Table 2.3.6.1-1 Configuration Items

The Commissioning Plan [CI-COMM] provides details about configuration items and deployment locations. See also the CI Network Design. 

Releases

The capabilities of the OOI Integrated Observatory are specifically designed in a way that supports an incremental transition to operations. In particular, the design supports five incremental releases of the CI that increasingly support user relevant applications and processes, beginning from automated data preservation and distribution leading to advanced concepts of interactive ocean science, including instrument and observatory interactivity exploiting knowledge gained through observations and analyses. Even though multiple subsystems and infrastructure elements are being developed simultaneously, each release has a specific theme targeted at providing value to the end users and building on value previously delivered.

The five releases will support user applications as follows (for more details, refer to the Transition-to-Operations Plan [CI-TTOP):

• Release 1 provides the Data Distribution Network, a fully capable automated end-to-end data preservation and distribution infrastructure, supporting the immediate needs of instrument providers and observational data consumers.
• Release 2 provides a Managed Instrument Network, adding end-to-end control of how data are collected and supporting more advanced processes of instrument providers with managed instrument control.
• Release 3 delivers OnDemand Measurement Processing. It adds end-to-end control of how data are processed, supporting more advanced workflows of instrument providers and data product consumers, as well as on demand measurements supporting event-driven opportunistic observations.
• Release 4 delivers the Integrated Modeling Network. It adds control of integrated ocean models driven by the data collection process, supporting data product developers and the numerical modeling community
• Release 5 delivers the complete Interactive Ocean Observatory by adding control of data, processes, and models to drive the collection process, supporting observatory interactivity and transformative ocean observatory science for all users.

In its final deliverable after Release 5, the CI will provide:

• Real-time modeling and data assimilation.
• Adaptive sensing and platform control.
• Rapid response and event capture.
• Closed loop, integrated sensing, modeling, and distributed network control.

Master Schedule

Work Breakdown: Subsystems

The work breakdown and design of the OOI CI supports the incremental construction in five releases by six subsystem integrated product teams (IPT). Each subsystem IPT is responsible for the delivery of the respective subsystem services for each release. Once integrated, the subsystems will operate services networks within the Integrated Observatory system of systems.

The six subsystem IPTs are:

• Sensing and Acquisition (S&A) Subsystem Integrated Product Team
• Data Management (DM) Subsystem Integrated Product Team
• Analysis and Synthesis (A&S) Subsystem Integrated Product Team
• Planning and Prosecution (P&P) Subsystem Integrated Product Team
• Common Execution Infrastructure (CEI) Subsystem Integrated Product Team
• Common Operating Infrastructure (COI) Subsystem Integrated Product Team

The integration of tools and applications is based on the framework that the CI infrastructure provides, in particular the service-oriented integration architecture based on governed message exchange. The deployment of system entities across the observatory network is also based on the framework that the CI infrastructure provides. The following sections provide further details about the subsystems and the releases to the degree relevant for the CI architecture and design specification. Further details are covered in the project plans, in particular the System Engineering Master Plan [OOI-SEMP], Transition-to-Operations Plan [CI-TROP] and the Commissioning Plan [CI-CP]. Figure 4.1.1-2 shows the planned construction and integration of subsystems into the five CI releases.

Subsystem Releases

All system and subsystem level deliverables comprising the CI will be constructed by the six subsystem IPTs and integrated by the integration, test and validation team. Deliverables include:
