EarthCube white paper status and plan (Chris)

• Background
  • NSF Earth Cube program
    • "NSF seeks transformative concepts and approaches to create integrated data management infrastructures across the Geosciences. In a new partnership, the Geosciences Directorate (GEO) and the Office of Cyberinfrastructure (OCI) recognize the multifaceted challenges of modern, data-intensive science and education and envision an environment where low adoption thresholds and new capabilities act together to greatly increase the productivity and capability of researchers and educators working at the frontiers of Earth system science."
    • Earth Cube Webinar on July 11, 2011 (Powerpoint presentation)
      • "A need to transform the conduct of science and education over the next decade"
      • "NSF seeks transformative concepts and approaches to create a sustained, integrated data management infrastructure spanning the Geosciences."
• Current White Paper Draft now on wiki
  • Title: A Grassroots-Federated Approach to Earth Science Data Discovery
    • are the words grassroots and federated redundant?
  • Authorship
    • should it come from the Cluster or from individuals?
    • Erin: could also have a section for people who support it can add their name to the list.
  • Technology framework
    • still need author for section on Servicecasting Framework. Ken volunteered.
  • Governance
    • Hook volunteered.
  • Looking to the future
    • expanded approach of Discovery to the overall Earth Science Collaboratory (ESC).
• Charrette
  • NSF will hold a charrette (community-driven meeting)
    • Now scheduled to be during first week of November.
    • Coincides with ESDSWG on Nov 1-3.
  • Is Ruth going to Charrette? Rahul (UAH) may also be going.

RFP for the Discovery Testbed proposal (Hook)

• the ESIP Testbed serves as a forum for innovative collaboration across all sectors of the Federation by enabling Federation committees and clusters to develop, test and improve availability and accessibility of member products and services.
• we submitted a proposal to the ESIP Products and Services Committee for a Discovery services testbed.
• Discovery Testbed Proposal
  • Title: Discovery Services and Clients: Interoperability Testing, Advertisement, and Assessment of Data to Service Broker
  • Description: The Discovery cluster provides a medium for Federation members to coordinate on development, deployment, and creation of interoperable specifications for Discovery services such as OpenSearch, DataCasting, and ServiceCasting. As such, a common testbed to deploy services and/or clients would enable the Federation members to test the interoperability of Discovery services and clients. More over, having a common testbed where Federation members from various data centers can access would provide a common platform that can be used to advertise their services. Currently it is difficult to know where services exist, what they do, and how to access them. Several machine-processable mechanisms for advertising services (such as service casting) have been evaluated by the NASA Tech Infusion Working Group. The testbed will provide an environment to demonstrate how Federation-wide member services can be advertised, described, and chained together using existing technologies. From this, new capabilities can also be explored such as enabling an association of data to services where for each data collection or granule, compatible services provided by Federation members can be shown.
  • ESIP Community Benefits: Improved interoperability of ESIP Discovery services and clients leading to broader adoption. Increased awareness and usage of Discovery services. Improved brokering of data collection and granules to compatible services that can use them.
  • Cost: $8K to (1) setup the testbed for allowing service and client implementations to be deployed onto the testbed, (2) setup a service cast of Federation member’s services offered, and (3) explore concept of data to service mapping.
• testbed proposal was approved
  • P&S pitched it to the SIP Finance Committee.
  • setup Configuration Board to review the implementation proposals.
• the committee is now is soliciting ESIP members to propose to implement the functionality.
• note here that the testbed idea proposal and implementation are not necessarily done by the same people
• last month, Ken Keiser sent out an email of this.
• A proposal should be one page or less in length and should specify:
  • Which task(s) the proposer is responding to;
  • The capability of the proposer to carry out the task(s);
  • Any special skills or intended outcomes that the proposer can bring to the task.
• Proposals
  • may be submitted by any ESIP organization, an individual within such an organization, or a team of such individuals.
    • Civil servants are restricted from receiving ESIP funds.
  • should include a CV for any participants (not part of the 1-page proposal).
  • should be sent to keiserk@uah.edu by Sept 15, 2011.

• ESIP Testbeds will be more prominent on the ESIP Portal.
• Architecture of testbed
  • some ideas include virtualization of testbeds
• Eric Rozell is interested in submitting an implementation proposal.

DCP 3 (superseding DCP 2): Proposal, schedule (Brian)

• DCP-2: Canonicalizing Granule-level OPeNDAP Links
  • was submitted for review in 2011-06-15.
  • essentially killed as new discussion has brought up more ideas.
• upcoming DCP-3 will be superseding DCP-2.
• DCP-3 will be more generalized (addresses more than just OPeNDAP).
• justification of needing a DCP that adds to the OGC spec. ESIP's needs for OpenSearch goes beyond OGC's spec.
  • adding esip-specific qualifiers for rel types.
  • recursion
• OGC has CSW 3.0 Part 4: OpenSearch Query Interface (presentation by Pedro Gonçalve)
• within the next month, Chris will write a ESIP position paper on comparison of ESIP and OGC position on OpenSearch.
• we should get a better understanding of CSW 3.0 and OGC OpenSearch first, before pursuing DCP-3.
• Brian will finish table of rel values for DCP-3.

Comparison of ESIP Federated Search with OGC OpenSearch

• The OpenSearch Query Interface was approved by the OGC Technical Committee to use the Fast Track process to become an OGC Candidate Standard.
• In July 2011, there was a public Call for Comments as part of the fast track process.
• OGC documents are difficult to access
  • it took Chris a few weeks to get access to it.
• OGC authors have many recognizable people
  • Pedro Gonçalves
  • Andrew Turner
  • Doug (FGDC guy)
• "optional" in OGC reads more like "should"
