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"
GEO Task AR-09-01b
Architecture Implementation Pilot
“fostering interoperability arrangements and common practices for GEOSS”
AIP-3 Focus Areas
• Technology Areas– Services Use Cases– Data Harmonization– Data Sharing– Semantics
• SBAs addressed– Energy– Disaster Management– Climate Change and
Biodiversity– Water Drought– Health: Air Quality
AIP Interaction with Users
• User scenarios drive development– Implemented through use cases– Scenario WG interaction with CoPs– Scenario demonstrations recorded for later se
• AIP support of UIC Usability Testing– GCI came from AIP-1– AIP supported GCI usability testing– Recommend usability testing for AIP-4 results
• AIP-4 focus on data to users– Increase access to UIC priority observations– Usability testing of access enablers
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
