Report on GEO Architecture & Data Committee (ADC) Meetings Ivan PETITEVILLE

1. Report on GEO Architecture & Data Committee (ADC) Meetings Ivan PETITEVILLE

2. ADC Meetings Since WGISS-21: • 3 Co-Chairs telecons • 2nd ADC meeting (Seattle, July 19-22, 2006) following GEONetCast workshop • ADC Full Committee meeting on July 20-21 • ADC Co-chairs meetings on July 19 and 22 • 1st Coordination meeting of the 4 GEO Committees Co-Chairs (Geneva, Aug. 30)

3. 2nd ADC Meeting – Major Outcomes • Good progress on the GEO 2006 WP reported by the GEO Secretariat • Some Major issues raised by ADC: • Lack of an overall project management • Inter-dependency between the tasks: no assessment of delays • Better communications needed between the various GEO Committees on linked tasks • No close monitoring of list of deliverables and of schedule progress w.r.t. to original plans. • Necessity to identify the core / foundation / critical tasks for GEOSS – high priority

4. 2nd ADC Meeting – Major Outcomes • Some Major issues raised by ADC (cont’): • No proper traceability of users requirements • Missing Tasks w.r.t. “GEO 10-year plan” targets • Uneven progress between Tasks • Lack of Overall System Engineering • Uneven reporting process at Task level • Lack of Task coordination from the POC • Necessity to regroup some Tasks • Better coordination needed for some architecture tasks

5. 2nd ADC Meeting – Major Outcomes • CEOS POC (~ Task Coordinator) for 3 GEO 2006 Tasks • Reports available • Major activity on CL-06-02 (GCOS)

6. 1st Co-Chairs Coordination meeting Major topics: • Relationship between the Secretariat, the Committees, the Executive Committee and the Plenary • Role of the task POCs vs the task members • Need for closer coordination across all tasks • Need to identify the few tasks that require the highest degree of cross-committee coordination • Overall GEOSS Project Coordination by GEO SEC. • Presentation of GEO 2007-2009 Work Plan

7. Adhoc meeting on System Engineering • Following 1st coordination meeting, adhoc meeting on GEO System of System engineering • Participants: ADC Co-chairs, GEO SEC and Actionee (Rob Husband for D.Hinsman-WMO & ADC Co-chair) • Complex problem: • today no overall system engineering approach (lack of resources) and several GEO architecture tasks executed independently • Need for defining a suitable overall system engineering approach to help GEOSS implementers (e.g. • general integration procedure, generation & distribution of a Implementers Manual (=handbook) with GEO-recommended standards

8. GEO System Tasks • Mainly addressed in : • AR-07-P1: Interoperability arrangements for GEOSS • AR-06-01 to 04 regrouped • AR-07-P2: Interface Implementation for GEOSS • "Clearinghouse task" (AR-06-05) and the "GEO Webportal task" (DA-06-07) regrouped • DA-06-04: Data, Metadata and products Harmonisation • DA-06-06: Spatial Data Infrastructures • DA-06-09: GEOSS Best Practices Registry • DA-07-P4: Data Integration and Analysis System • Potential Role for WGISS
