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

  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

  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

  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

  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

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

  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

  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

  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

  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

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

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

  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

  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

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

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

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

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

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

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

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

  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

  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

  29. Alternate Search Mechanisms • OpenSearch GEOSS Interoperability Workshop November 12-13, 2009

  30. Alternate Search Mechanisms Take Aways • Further work • Final decisions GEOSS Interoperability Workshop November 12-13, 2009

  31. Semantic Interoperability • What do we mean? • Near-term expectations (1 year) GEOSS Interoperability Workshop November 12-13, 2009

  32. Semantic Interoperability Take Aways • Further work • Final decisions GEOSS Interoperability Workshop November 12-13, 2009

  33. Standards Taxonomy • How do we review? GEOSS Interoperability Workshop November 12-13, 2009

  34. Standards TaxonomyTake Aways • Further work • Final decisions GEOSS Interoperability Workshop November 12-13, 2009
