The software Integration Strategy for the OOI Integrated Observatory Network rests on the following concepts, provided by the Common Operating Infrastructure (COI) subsystem.

Integration Strategy Elements

In particular, the integration strategy rests on:

Interacting Agents

(this is work in progress)

Agents play a central role in the management of the Integrated Observatory Network (ION) as a federated system of systems with no central domain of authority. Observatories and organizations can join the ION and choose to collaborate to a degree they choose autonomously. The ION as a system realizes a federation of such "facilities".

However, for OOI core assets (sensors, physical marine infrastructure, computation and storage resources), there will be some OOI wide governance in place, with possibility for an independent operation of Marine Observatories. Other facilities position themselves in their relationship to OOI (as data consumers, user platforms, science gateways or resource contributors).

Agents realize the domains of authority within the system in software and operational processes. Agents exist for resources such as instruments, compute clusters and software services. Thereby, the agents inject the authority of the owner and of the operating facility of the resources. Functionally, agents provide a command & control interface for resource, represent the resource state and send out event notifications in case of failures and state change, and provide a list of the resources capabilities.

Dependencies

The concept of agent based resource management is developed across several subsystem teams:

COI subsystem:

  • Defines the generic services and processes related to resource management within the OOI ION
  • Provides the services to define and manage facilities of independent domain of authority
  • Develops the governance services that manage and interact with agents
  • Develops the identity management and policy enforcement capabilities needed when working with agents and resources
  • Contributes the governance functions of a resource agent
  • Advances the conceptual background for contracts, commitments, facility affiliation
  • May lead the resource agent definition and integration effort

CEI subsystem:

  • Manages resources with behavior and state (taskable resources) through flexible management services.
  • Defines the resource agent to management services interface
  • Applies resource agents for computational resources (physical and software)
  • May lead the resource agent definition and integration effort

DM subsystem:

  • Limited involvement in the area of information resources and their governance

S&A subsystem, with instrument and platform agents (IPA):

  • Applies resource agents for instrument (sensor) and platform resources
  • Drives the concepts of proxy agents representing remote

Timeline

In Release 1 there will be only one facility, the OOI ION facility. This means one domain of authority but multi-site deployment. Therefore, any issues related to multiple domains of authority will not be addressed in this release.

The agent concept will be evolved first with a focus on resource management (control, monitoring, failure detection, access policy enforcement and capability listing).

In Release 2, Marine observatory facilities will be supported. Two marine facilities will be operated within OOI for CG and for RSN.

In Release 3, laboratory and classroom facilities will be supported. Some of these will be operated by OOI. Others may be operated by other organizations that have an interest to interact with OOI.

In Release 4 and 5, interactive observatory facilities will be supported. They are a logical extension of Marine facilities with the purpose of
