Architecture Priorities

Why do stakeholders perceive that the architecture does not meet needs? Users are not seeing what they expect The interaction or UI is cumbersome and requires human intervention Scientists already find what they need in their communities No perceived GEO-added value Insufficient outreach on successful solutions

What emerging architectural elements should be introduced? Focus on data-side services to be deployed as the primary value-add of GEO Support for an organic vocabulary for observable properties (ontologies) Supporting web service integration and chaining (work flows, mashups)

Moving R&D into later operations Ontology support and brokered search is demonstrated by EuroGEOSS and should be evaluated for transition to GCI operations. Select among datasets from EuroGEOSS. FedEO and GENESI-DR “demonstrator” search of imagery inventories could be enabled and integrated into GeoPortal search using OpenSearch-geo. Subset of data sets to be identified from Observational Priorities. [ESA]

GCI enhancements Single search capabilities against Clearinghouse from GEOPortal Flag and deploy of categories/tags (location, time, publisher, Data-CORE, “no cost,” data quality, etc.) in order to group/manage results Render selected services found through Clearinghouse (i.e. mapping WMS, GeoRSS) Investigate and improve ranking of results Integrate User Requirements Registry with GCI

CSR/Clearinghouse improvements Simplify registration process and “resource types” Allow association of multiple standards with any resource Support ISO metadata as core model Investigate consolidation of CSR and CH as a single search engine Expose all CH metadata as HTML and sitemap.xml for commercial search engines (CSE)

Architecture Implementation Pilot (AIP-4) AIP-4 will focus on promoting high-priority data sources to be exposed as online web services to enable maximum re- use, show rapid progress Start with Observation Priorities from UIC, Data-CORE nominations, and other key data sets (i.e. ECV, ETV) Support a taxonomy to ‘flag’ these resources for search/presentation in GeoPortal and CH Enable end-user visualization and data access through the GEO Web Portal Promote extensive outreach on the success of projects, engage selected user communities, UIC, CBC, incidental to the testing and deployment process Frame outcomes and recommendations to ADC/GEO from AIP-3 – reformulate the summary and resolutions

Metadata Identify and build consensus on “Minimal GEOSS Metadata” Profile of ISO metadata and Profiles recognized and mapped for use in GEOSS Address GEO-specific fields/tags to be managed, to be subject of next CC telecon – need work telecon first to also address among GCI Providers and invited experts: – Data-CORE flags and links and – Data quality and links to references Support data semantics – ontology for data containing priority observation parameters stored in ISO or as supplemental structured metadata (as RDF/OWL/SKOS?)

Action: Facilitate deployment Use as reference the common set of observational parameters – priority observations - from US Table 13 and Data-CORE list [AIP Team and GEOSec SBA experts (George) – March, initial] Identify accessible data sets supporting the observational parameters, working with subject experts, to enable online services (review Data-CORE survey) to showcase priority data access. Capture status of accessibility [(Rob) SME/Secretariat experts, data providers, AIP, GCI operators - April] For gaps (parameters in data sets that are not internet accessible), contact key providers via the Secretariat and ADC to add extra service adapters to priority data sources [(Rob) Secretariat – May] Demonstrate client access to GENESI-DR, EuroGEOSS, AIP-4 services for users [(Mirko, Jay, AIP Team) ESA – May/June] Enable online services to showcase priority data access by 2011 Plenary with full data access through the GEO Portal - “Services on the data” Include Data-CORE and quality declarations, proper metadata, support standard data access service interfaces [(Mirko, George) data providers, AIP, GCI operators – September] Demonstrate integrated access to critical GEO resources for the Plenary [(Gary Foley) October] Integration/use of the priority observation data – consult with UIC Communities of Practice for demo. Measure usage/access, usability assessment [UIC (Gary Foley) - November]

New Activity Proposal Need a support team that can assist in registering new data sources and in deploying quality Web services – Intervention, proactive: target priority data providers – Support capacity building and showcases – Work with priority communities and data resources to prove value-add – Engage commitment at the management level – Need sponsors/participants

Activity: Operations and Enhancement Process has been proposed for Ops and Enhancement Board or Team to include all GCI providers and key stakeholders to accept and process bug fixes and enhancements Supports formal management of enhancements and fixes to all of the GCI system components Have held multiple GCI Providers telecons to address urgent issues – need a formal recognition and host for this before the next work cycle

Task: GEOSS Architecture Replacement of AR-09-01a Maintains and updates the latest requirements and designs of the GEOSS Architecture to respond to requirements on a periodic cycle Supports strategic and tactical approach, documentation, and outreach

Task: GEOSS Development Update on AR-09-01b Continues the AIP R&D process provides feedback and recommendations for operations

Task: Ontologies Update on AR-09-01d with EuroGEOSS Maintain registry of ontologies from communities Building ontology of observation parameters with all data offerings and user requirements Facilitates brokered “smart” search and data integration Includes operational and research scope – clarify interactions
