Status Report on SIF to GEO ADC 6 Feb 2008 Siri-Jodha Singh Khalsa IEEE
Contents • • • Background Recent Meetings Current work Regional Teams Outstanding Issues Schedule and Future Plans
GEOSS Interoperability Process • The purpose and design of the GEOSS architecture is centered on the goal of enabling and promoting synergy among diverse and independent systems – Thus the emphasis in GEOSS on interoperability • The first task in the first GEO Workplan in the Architecture category (Task AR-06 -01) was to “Establish and maintain a process for reaching interoperability arrangements, . . . ” • Includes process for recognizing existing standards in use by GEOSS components, and promoting and encouraging their adoption by other participants – helps extend and broaden whatever consensus has been achieved on common solutions.
GEOSS Standards Registry • The GEOSS Standards Registry is the reference database of interoperability arrangements for GEOSS – Contains information on service types, access protocols, data formats, schemas, and other information necessary to access and utilize the resource – Services registered in the Service Registry reference standards, or other interoperability “Special Arrangements, ” registered in the Standards Registry
Special Arrangements (link from http: //geossregistries. info)
The SIF • Although GEO encourages the use of open international standards, GEOSS must also accommodate the use of non-standard practices • So the Standards Registry also contains information on these non-standard practices, what are called “special arrangements. ” • The process for entering special arrangements into the Standards Registry is handled by the Standards and Interoperability Forum or SIF
SIF Purpose and Goal • The Standards and Interoperability Forum provides advice, expertise and impartial guidance on issues relating to standards and interoperability for GEOSS. • The SIF’s goal is to enable ever greater degrees of interoperability among GEOSS components through facilitation, technical analysis, advocacy and education
SIF Objectives • The primary function of the SIF is to address situations where GEOSS components cannot interoperate using one of the registered standards or other interoperability arrangements. • The SIF will perform analyses and make recommendations to GEO Members and Participating Organizations that come to it for assistance with interoperability issues. • The ADC will call upon the SIF to support consensusseeking in matters of GEOSS interoperability. • The SIF will support education and outreach to increase awareness of standards used in GEOSS.

SIF Terms of Reference and Ops Procedures • The SIF Terms of Reference approved by co-chairs – distributed to ADC in September 2007 • The SIF Draft Operating Procedures reviewed by cochairs – Available on SIF ftp site
Recent Meetings • Three meeting (Webex) since Cape. Town – 6 th SIF, 2007 Nov 11 – 7 th SIF, 2007 Dec 20 – 8 th SIF, 2008 Jan 24 – Averaging 11 participants • Minutes, other documents on ftp site – ftp: //ftp. wmo. int/Projects/GEO/SIF
Registry Scrub • Seventy-two service entries analyzed • Looked for standards and special arrangements listed in service registry – Some match entries in standards registry, many don’t – Some don’t have contact information! – Requires contacting submitter for clarification, ask to fix entries as needed – Encourage to submit SAs as candidate entries for standards registry • Will soon have service registry standards picklist updated automatically from standards register
SIF Workflow • Developing workflow for SIF deliberation process – Every step of the process tracked, as an official workflow, and stored in a task database for easy review. – Regional teams are free to use SMEs as necessary. – At the end of handling a task, it is possible that the SCC may need to be involved.
Regional Teams - Established • SIF-China – Dr. Jiashen Zhang, co-chair, w/ Dr. Wenxiu Gao • SIF-Japan – Prof. Shibasaki, co-chair, w/ Mr. Takagi • SIF-S. America – Mrs. Patricia Alvarez, CONAE
Regional Teams – in Development • SIF-Europe – Stay tuned. . . • SIF-N. America – Martha Maiden, NASA HQ, • SIF-India – Vjay Jayaraman, ISRO, awaiting reply • SIF-Africa? • SIF-Australia?
Issues • Reconciliation of regional standards/profiles with GEOSS interoperability objectives • Granularity in standards registration • Registration of draft standards, before formal standardization process complete • Periodic reports on referenced standards and Special Arrangements from Services Registry • Linkages with Best Practices Wiki
Future Plans • Continue monthly telecons of core group • Initial meeting of Regional Team Leads proposed for 1 st week of March • Begin transfer of tasks to RTs • Opportunities for face-to-face meetings – Rotate between RT locations (Japan, Europe, India, China, S. America, U. S. ) – At GEOSS Workshops? – International conferences?
