  1. Grid OGC Collision - the SEE-SAW projects Open Grid Forum 20 (OGF20) 7th May, 2007 Chris Higgins (EDINA, University of Edinburgh) Gobe Hobona (University of Newcastle)

  2. Grid OGC Collision Programme • JISC (Joint Information Systems Committee) Programme • Committee of the UK HFE funding councils • Supports teaching, learning, research and administration • Provides strategic guidance to UK HFE on use of ICT • Grid OGC Collision in context of wider UK e-infrastructure • “…embraces networks, grids, data centres and collaborative environments, and can include supporting operations centres, service registries, single-sign on, certificate authorities, training and help-desk services.  Most importantly, it is the integration of these that defines e-Infrastructure.”

  3. Grid OGC Collision Call • Call came out Mar 06 • Area A on Security (EDINA SEE-GEO project) • Prototype of one or more OGC web services (with client) • Proposals to OGC on how to modify the OGC web service standards to support such secure access • Area B on Workflow (Newcastle SAW-GEO project) • Developing and extending workflow engines to support and orchestrate OGC services • Area C on OGC Liaison (EDINA leading) • Contributions to OGC technical meetings and reporting on developments to the e-science community

  4. SEcurE access to GEOspatial services • Aiming to demonstrate how access to Geospatial Information on Grid may be achieved: • Shibboleth • WS-Security • Grid Security Infrastructure (GSI) • OGC Web Services • Partners: EDINA, NeSC, NCeSS, MIMAS • Main deliverables are a report and 3 demonstrators: • National datacentre • e-Social Science • Orchestration (Newcastle)

  5. e-Social Science Demonstrator • Being implemented within the context of the OGC’s Geolinking Interoperability Experiment (Geolink IE) • IEs are brief, low-overhead, formally structured and approved initiatives led and executed by OGC members to achieve specific technical objectives that further the OGC Technical Baseline. • Aim: implement a number of prototype GeoLinking services based on the interface specification originally described in the Geolinked Data Access Service (GDAS) and GeoLinking Service (GLS) Discussion Papers. • Purpose: confirm that OGC specifications completely support the ability to link attribute data to its geospatially representations when stored at separate locations on the Internet, and to improve the specifications if they do not support these requirements.

  6. e-Social Science Demonstrator

  7. e-Social Science Demonstrator

  8. e-Social Science Demonstrator • Schedule: now moving into deployment phase • Integration of components • Bugfixing • Testing (including performance testing of use of OGSA-DAI as a GLS • Technology demonstration • Interoperability with components provided by other IE participants • July 16th. Final report submission (OGC Interoperabilty Programme Reports)

  9. What does OGSA-DAI give us? • OGSA-DAI activities, a simple pipeline, eg, GDAS getData, GLS geoLink, WFS getFeature • Additional GLS implementations simplified if activities already exist (multiple different ways to implement GLS) • We can now do the following with relatively little extra work: • Choose different framework datasets dynamically • Merge GDAS XML directly into an RDBMS dataset • Implement filters, eg, bbox, currently must use geolinkage field values (geolinkids) • Transfer data using GridFTP • Protect using GSI? • Experiment, play with what we have…

  10. Where next for SEE-GEO? • By July, complete participation in the OGC Interoperability Experiment • Switch focus back onto security aspects, especially developments within the OGC space • How can we make the e-Soc Sci demonstrator secure? • Shibboleth • Grid Security Infrastructure (GSI) • PrivilEge and Role Management Infrastructure Standards Validation (PERMIS) • Demonstrator #2. Ordnance Survey MasterMap on the NGS?
