GEOSS Interoperability ArrangementsGEOSS Interoperability Arrangements- From the GEOSS 10 Year Plan Reference Document - - From the GEOSS 10 Year Plan Reference Document -

• Interoperability through open interfaces– Interoperability specifications agreed to among contributing

systems– Access to data and information through service interfaces

• Open standards and intellectual property rights– GEOSS adopting standards; agreed upon by consensus,

preference to formal international standards– GEOSS will not require commercial or proprietary standards– Multiple software implementations compliant with the open

standards should exist– Goal is that at least one of the implementations should be

available to all implementers "royalty-free"

Standards and Interoperability Forum

GEOSS Common Infrastructure (GCI)

Standards and Interoperability Forum (SIF)

• Purpose: Provide advice, expertise and impartial guidance on issues relating to standards and interoperability for GEOSS.

• Goal: Enable ever greater degrees of interoperability among GEOSS components through facilitation, technical analysis, advocacy and education

• SIF Activities– Maintains and oversees the GEOSS Standards aind

Interoperability Registry (SIR)– Currently conducting GEOSS interoperability

assessment

GEO Task AR-09-01b

Architecture Implementation Pilot

“fostering interoperability arrangements and common practices for GEOSS”

AIP Architecture Elements

• Components – Manageable units hardware, software, networks

• Services– Methods for components to interact using GEOSS

Interoperability Arrangements • Use Cases

– Describe what can be done with Services, e.g., Discovery, Access, Workflow, etc.

• Scenarios – Meet SBA User needs;

accomplished with Use Cases
