1. GEOSS Interoperability Workshop November 12-13, 2009 1 SIF Technical Talking Points

2. GEOSS Interoperability Workshop November 12-13, 2009 2 Standards Convergence Assumption is that short list of consensus standards is desirable What’s the goal? –Interoperability between prime data sources Criteria selection (most already in place for SIR review) –Easy to implement –Availability of reference implementations, tools –Maturity –Stability/maintained –Well documented Engage w/ community developing stds/tools

3. Categorize by application Impact on GEOSS and GCI What’s the process? –Rating system –SIF recommendations –Survey Need tools to go along w/ stds to make it easy to be conformant Limit proliferation of profiles GEOSS Interoperability Workshop November 12-13, 2009 3

4. User Perspective Smithsonian –How to enhance interdisciplinary science –Recommendations on website –Directive to be more relevant, accessible, engage in more collaboration –CIO: interested in curation –Wants to leverage similar efforts –No uniform policy on standards, data management STRI driver, bio, ecology GEOSS Interoperability Workshop November 12-13, 2009 4

5. attitude Would they take guidance from GEOSS? –Willing to take guidance, adhere to what’s in widespread practice or recommended –They also need “instant success” EPA –put in context of stds efforts across agencies/nations (bio, water, etc. elsewhere) –Bound by SBA mission? –Looking to GEO for leadership of EO, geospatial stds for envr. Assessment GEOSS Interoperability Workshop November 12-13, 2009 5

6. EU (ocean, gbif) Motivating data providers to adopt stds Community–centric view Real asset is cross-discipline interop Adverse to ranking Intra-community stds vs. inter-community stds –Heterogeneity of profiles –Bridging / mediation GEOSS Interoperability Workshop November 12-13, 2009 6

7. GEOSS Interoperability Workshop November 12-13, 2009 7 Standards Convergence Rating system –User-driven CoPs –Could publish in Bpwiki –Challenging –What is process communities use to decide

8. Just publish preferred Just tell me how to do it –Tools –Cookbooks –Guidelines JAXA –Hears conflicting requests for stds –CFP vendors don’t reply because specs in English GEOSS Interoperability Workshop November 12-13, 2009 8

9. Find providers willing to participate in study of what’s required to make data available in GEOSS –Case studies, exemplars –Is what AIP is doing? –Works better when approach via CoPs Water quality (ESIP): Find leading ontologies, semantic arch, display an integration tools, use cases –What’s in use, what’s working GEOSS Interoperability Workshop November 12-13, 2009 9

10. Role of SIF? –Recipient of AIP findings –Do studies? Surveys? Communities unlikely to change ways they do business, but still wish to share data –Bridging stds –Rank stds by how many other stds “link” to it –How to determine? If CSR/SIR fully populated might prive GEOSS Interoperability Workshop November 12-13, 2009 10

11. Basic assumptions Must accept all offerings –And provide information on how they do business –Parallel experiment highlighting what’s working Interative effort, fill gaps Positive deviance –Support/showcase desired behavior GEOSS Interoperability Workshop November 12-13, 2009 11

12. Advocacy Work w/ early adopter, showcase success –Bridging the “chasm” GEOSS Interoperability Workshop November 12-13, 2009 12

13. Humanity at critical juncture EO information essential to make informed decisions GEOSS Interoperability Workshop November 12-13, 2009 13

14. Politics & Process Maintain current process –SIR, rating process –Utility of portals in question, but registries – tuned to work with active communities, are impt In parallel –Work w/ CoPs to demonstrate successes GeoBON developing architecture, scenarios –Lessons from AIP Global identifier scheme Determine and communicate “best standards” Support framework data and standards data types GEOSS Interoperability Workshop November 12-13, 2009 14

15. Proposal from Sonntag –Semantically linked data, from self org in communities, ontologies –RDF expressions, will be defacto in data sharing GEOSS Interoperability Workshop November 12-13, 2009 15

16. GEOSS Interoperability Workshop November 12-13, 2009 16 Standards Convergence SIF recommenations

17. GEOSS Interoperability Workshop November 12-13, 2009 17 Standards Convergence Public survey

18. GEOSS Interoperability Workshop November 12-13, 2009 18 Standards Convergence Take Aways Further work Final decisions

19. GEOSS Interoperability Workshop November 12-13, 2009 19 Data Access Authentication/single login –Keeping track of users; barrier to entry? –Centralized means for authentication and access to use data would be useful Digital Rights Management (DRM) –Licensing Provenance/Attribution Acknowledgment to producers for publishing Billing

20. GEOSS Interoperability Workshop November 12-13, 2009 20 Data Access Authentication/single login –Central Authentication Service (CAS) http://www.jasig.org/cas Created at Yale In use since, at least, 2004 OpenID –Used by government –Decentralized Fewest obstacles to registering and tracking users – see AIP-3

21. GEOSS Interoperability Workshop November 12-13, 2009 21 Data Access Digital Rights Management (DRM)

22. GEOSS Interoperability Workshop November 12-13, 2009 22 Data Access Provenance/Attribution

23. GEOSS Interoperability Workshop November 12-13, 2009 23 Data Access Billing

24. GEOSS Interoperability Workshop November 12-13, 2009 24 Data Access Take Aways Further work –see AIP-3 for practical exercise in simple registration and data sharing –Additional process needed for data providers with greater restrictions than tested in AIP-3 Final decisions –SIF will follow work done and encourage documentation in Best Practices WIKI –Update Tactical and Strategic Guidance on usage of GCI (AR-09-01a)

25. GEOSS Interoperability Workshop November 12-13, 2009 25 Usage of GEOSS Resources Automation Publish-Find-Bind use case

26. GEOSS Interoperability Workshop November 12-13, 2009 26 Usage of GEOSS Resources Take Aways Further work –BP Wiki needs content! –Links to BPWiki from Wikipedia –Point to user blogs of experiences using GEOSS –NASA SPG will add BPWiki content, with links to SPG source docs –BP’s to be registered for direct linkage to GCI

27. GEOSS Resources Take-away BPWiki –All of these proposals for standards convergence, capacity building etc just discussed now etc can go there now –The wiki should not be bound by any particular format constraints. Short or detailed contributions can go there. GEOSS Interoperability Workshop November 12-13, 2009 27

28. GEOSS Resources Take-away Standards Registry –Add links to Schemas and validators, and test frameworks, for standards in the registry GCI guidance? –Consolidated requirements not sufficient to promote complete interoperability Need to specifiy which data model, which version of standards for a well-established base line But this is very CoP-dependent Bridging/mediation may be needed between multiple community standards GEOSS Interoperability Workshop November 12-13, 2009 28
