GEOSS

GEOSS Interoperability Arrangements - 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"

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 Support SBAs by developing new process and infrastructure components for GCI and the broader GEOSS architecture Evolutionary Development thru AIP Phases Demonstrate and document results to inform GEOSS Development progress 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
