GEOSS, the Global Earth Observing System of Systems, is being built from existing systems and initiatives, with
an emphasis on the creation of synergies among GEOSS component that provide increased benefits to society.
The goal is to leverage existing programs and established standards wherever possible, and to broaden
convergence of systems based on agreed interoperability arrangements.
This talk will describe the specific approaches that GEOSS has proposed for achieving interoperability among its
component systems and will give an overview of the GEOSS Interoperability Process Pilot Project (IP3). The IP3
was conceived as a way to exercise the process that has been defined for reaching interoperability
arrangements. We describe the phases and status of the IP3, which begins with identification of the system
components, and the standards, interface protocols and interoperability agreements currently in use by these
systems. This information is captured in web-accessible catalogs and registries that are part of the core GEOSS
architecture.
Four systems/disciplines were initially identified as sources for the pilot project, covering weather and climate,
seismology, biodiversity, and water cycle. This selection was based on the desire to have participation from
diverse disciplines and the commitments of representatives from the disciplines to actively support the process.
Systems contributed to GEOSS are built to serve particular needs, but those systems should also be designed or
adapted so their inputs and outputs support interoperability with other systems. Consequently, we focus on
interoperability situations that are surfaced by actual requirements to interface with other GEOSS- affiliated
systems through what are termed GEOSS interoperability arrangements. Use case scenarios were developed
that required the exchange of data and information between the identified systems. In designing interfaces to
support interoperability among two or more component systems of GEOSS, the objective is to deploy a solution
that not only solves the interoperability requirement, but does so by taking full advantage of existing international
standards.
The IP3 has provided valuable practical experience which is helping to refine the process for reaching
interoperability arrangements for GEOSS. This includes working with the nascent Standards and Interoperability
Forum, the GEOSS mechanism for facilitating interoperability. This project is also contributing to the design of the
GEOSS Standards and Interoperability Registry, which is the repository of information on the interoperability
arrangements employed among GEOSS components, and has provided initial content for the GEOSS
Components and Services Registers.
