• Nga Chung
• Ruth Duerr

Action Items

• Anyone: Add your OpenSearch service to the list of servers!
• Chris: Put out poll for DCP-4 at the end of the meeting
• Ruth: Write up NSIDCs solution for valid parameter values for DCP-5
• More detailed planning for the hack-a-thon (logistics/follow-up/etc.)
• Think about offering a VM that people can use to deploy Discovery technologies

Previous Action Items

• Chris or Hook will deprecate DCP-2 and DCP-3 on DCP page
• Brian will work on generalized version of DCP-4 (Pedro will contribute examples for WxS)
• Chris will send out Doodle poll for DCP-4
• James will update examples for DCP-4 with details and additional examples (also include all the different OPeNDAP MIME types) (also, try to use real links) (also put an example with a "length" attribute)
• All review DCP-6 if interested (only a few hours left!)
• Hook will continue to tweak DCP-7 before voting

Planning for the ESIP Summer Meeting

• Not necessarily bad for Discovery to have limited sessions
  • We don't need as much planning,better to integrate across sessions
• Need to collect participants at the Discovery cluster meetings
• Try to gauge what people are interested in through polling
• Get the code written during the hack-a-thon to become "community property"
  • Could use GitHub
  • Have slides showing how to checkout/checkin code

Brokering and Beyond - A glimpse at the Future of Global Data Sharing

• Related to Discovery (overview of the concept of brokering)
• More closely aligned with ESC

Discovery Hack-a-Thon

• Done a lot of work deploying services and working on standards
• Last "missing link" is how to enable more clients to actually use services
• Presenting a few "low-hanging fruit" ways of accessing services
  • Shell script w/ wget/curl
  • XSLT
• Idea is to show people how easy it is to access discovery services
• Ruth: Could it also be about the server-side? What about: "This is all you have to do to service-cast your data"
• Would also include time for the testbed.
  • Want people tinkering with the testbed
• Need to have mentors / teachers for each area
  • Should there be a Perl area, Python area, CSS/XSLT, etc.
• Designate some points of contact for after the session
• Put together a resources page for each "dialect" of the hack-a-thon
  • Also can throw together a presentation for each
  • Ideally, people would be able to bring something home with them
• Ruth could mentor for NSIDC's services / casting tools (at the simple level)
• Email list if you have an OpenSearch service you want to develop clients for
• Thomas could mentor Python
• Some would want to see more "enterprise-level" clients, like Java
• Could give a Groovy example for Java developers
• Best if there were multiple services to test clients on
  • Revisit / update the list of OpenSearch services

Metadata Casting for Data, Services, & Events/Topics

• Talking about casting standards

Open Source Software evaluation - ESRI's Geoportal Usability Test

• Some discussion of OpenSearch when reporting usability

Discovery Planning Session - Need to be added?

• Can this be merged with Brian's Metadata Casting?
• Could do a planning meeting on a telecon
• A lot of the things we are doing for Discovery are overlapping with ESC

ESIP Testbed: Encouraging Technology Innovation for Earth Science

• There will be an update from ESRI on discovery testbed performance

Update on DCPs

DCP-4

• See Discovery Change Proposals
• This was not merged with DCP-7/8
• Chris will put out poll for this, action item noted

DCP-5

• Is Ruth's group interested in writing DCP-5?
  • Ruth's not sure that someone is writing this up
• Since there are no better ideas, Ruth will write up NSIDCs solution to this

DCP-6

• This DCP only got 5 votes.
• Chris could have sent out more nag messages

DCP-7

• Hook says this is ready for vote
• Hook will be posting the link to the poll
• Polls should be posted on the cluster announcement page

DCP-8?

• Brian's generalization of the OPeNDAP links (DCP-4)
• Not sure when this will be done

Discovery Testbed

Amazon Testbed

• Testbed might be available through Amazon
• There isn't a specific way to deploying a testbed
  • Erin was happy to have ESRI be the guinea pigs for deploying a testbed
• Will be setting up a vanilla GeoPortal on Amazon
• Some outstanding questions:
  • How much does it cost?
  • How to give people access / logins?
  • ....

Contributing to GeoPortal

• The way to test use cases is to submit services to the GeoPortal
• There were people interested in developing
  • Products and Services team suggested GitHub for SCM
  • Speak up soon if you don't like GitHub!
  • Procedure: Post changes to GitHub and ESRI will test this
• Looking for people willing to test GeoPortal and report bugs / things they don't like
• Looking for people willing to document
• Send Christine your URLs to OpenSearch and data/service casts
• GeoPortal has various roles
  • need to identify people to approve content
  • a technical PoC for Amazon problems

GeoPortal in Summer Meeting

• GeoPortal may be relevant to Chris Mattmann's open source sessions
  • reply to Chris's request for presentations
• Talk to Steve Brody for information about the broker session
• There may be a "GeoPortal corner" at the Discovery Hack-a-Thon
  • Dedicating 25 minutes may not be possible
• ESRI can get a list of Discovery services from the same page being used for the Hack-a-Thon

"Relax NG" Validator Service

• Brian is not on the telecon, so this is being pushed to the next telecon
