  3. Brokering Concept Award • EarthCube’s goal is “To transform the conduct of research in geosciences by supporting community-based cyberinfrastructure to integrate data and information for knowledge management across the Geosciences.” • What is needed? • Integration of data, tools and communities through a cyberinfrastructure • Utilization of current and emerging technologies to create a transparent infrastructure for the geosciences community • The EarthCube approach: • “Build it and they will come” doesn’t work • What gets built has to be the result of a community process, where the community is much more than the IT enthusiasts

  4. Brokering Concept Award • Our objective • Develop a strategy and roadmap for evaluating promising brokering technologies in cooperation with a diverse set of US and international partners • Our approach • Develop and communicate a long-term strategy and roadmap for fully developing brokering as a core Earth Cube cyber-infrastructure component • Demonstrate and assess several instances of brokers that mediate search and access to heterogeneous multidisciplinary data sources and services

  5. Brokering Concept Award • Expectation • Engage the long tail folks, who are part of the 85% of geoscientists who will be training the next generation • Bring them onboard, understanding at some level what we’re doing and what is involved, helping to change the way science is done • Technical assessment responsibility • Pilot studies with different scientific communities • Hack-a-Thons in conjunction with ESIP

  6. Brokering Concept Award

  7. Brokering Concept Award • Working Definition of a Brokering Framework: • Brokers are middleware interconnecting client and server components in the EarthCube cyber-infrastructure. • Brokers are services facilitating the run-time interconnection (sharing of resources) among users and providers in a way that requires little effort on the part of either. • A brokering framework can consist of multiple brokering components to support different capabilities. • A Brokering framework may include discovery, semantic enhancement and natural language, data access, processing and publishing.

  8. Brokering Concept Award • Our brokering “Hack-a-Thon”: • Is an experiment with brokering alternatives • Allows data providers and data users to “play” with brokers • Will expect feedback from participants • Our Hack-a-Thon goals are: • To assess the ease with which brokers can be configured to mediate interactions between clients and services • To assess the ease with which client applications can access various brokers for the purposes of discovering and accessing data • To collect critiques and suggestions from the user community (data users and data providers)

  9. Introduction to the EuroGEOSS Broker • The EuroGEOSS Broker was developed by the Laboratory of Earth and Space Science Informatics (ESSI-Lab) of the Institute of Atmospheric Pollution Research (IIA) of the National Research Council of Italy (CNR) • It has been deployed at many organizations, such as: • GEOSS Common Infrastructure • NSIDC • UNEP-Live • It’s capabilities include discovery, access, and semantic mediation • New “accessors” can be added to interoperate with data providers using standards currently unknown to the broker

  10. Introduction to the EuroGEOSS BrokerSupported Sources • ESRI ArcGIS Geoportal (version 10) catalog service • OpenSearch 1.1 accessor • OAI-PMH 2.0 (support to ISO19139 and dublin core formats) • NetCDF-CF 1.4 • NCML-CF • NCML-OD • ISO19115-2 • GeoRSS 2.0 • GDACS • DIF • File system • SITAD (Sistema Informativo Territoriale Ambientale Diffuso) accessor • INPE • OGC WCS 1.0, 1.1, 1.1.2 • OGC WMS 1.3.0, 1.1.1 • OGC WFS 1.0.0 • OGC WPS 1.0.0 • OGC SOS 1.0.0 • OGC CSW 2.0.2 Core, AP ISO 1.0, ebRIM/CIM, ebRIM/EO, CWIC • WAF Web Accessible Folders 1.0 • THREDDS 1.0.1, 1.0.2 • THREDDS-NCISO 1.0.1, 1.0.2 • THREDDS-NCISO-PLUS 1.0.1, 1.0.2 • CDI 1.04, 1.3, 1.4, 1.6 • GI-cat 6.x, 7.x • GBIF • GeoNetwork (versions 2.2.0 and 2.4.1) catalog service • HYDRO • Deegree (version 2.2) catalog service

  22. Demo Q & A

  23. Hack-a-Thon Logistics • From Monday, May 14 until the Hack-a-Thon, participants will be able to access a Hack-a-Thon instance of the EuroGEOSS Broker for testing discovery and access at their convenience: • Try the user interface to test the capabilities • Try interoperating with your client application to discover and access data • Try making your data discoverable and accessible • May require asking for configuration changes • Requests for assistance should be made via email to Steve Browdy and Mattia Santoro explaining the issue • Follow-up will be handled on a case-by-case basis • New accessors and profilers will not be developed

  24. Hack-a-Thon Logistics • Participants should come to the Hack-a-Thon with clients and services properly interoperating with the EuroGEOSS Broker • Hack-a-Thon will allow participants to take turns, using WebEx, to demonstrate sharing data • Assistance will be provided in real-time for issues that arise • Feedback will be gathered, but can also be submitted offline • Need to set a date and time for the 2-hour Hack-a-Thon • Use doodle? • Decide now (May 24 from 11 AM – 1 PM EDT)

  25. Hack-a-Thon Logistics • Email sent to Hack-a-Thon participants by May 14 to convey important information with regards to accessing the EuroGEOSS Broker, emailing for assistance, and receiving assistance • Brokering team must supply participants the URL to access the user interface of the EuroGEOSS Broker • Brokering team must supply participants the URL to access the catalog profilers for discovery • Data providers must supply URLs to service interface endpoints • The contents of the email will also be made available on the Brokering Concept Award EarthCube site.

  26. Hack-a-Thon Logistics • Currently, 3 Hack-a-Thons are planned • Subsequent Hack-a-Thons will be handled similar to this one • Possibly modified a bit to deal with lessons learned and feedback supplied • Participants will be contacted when a new Hack-a-Thon will take place
