Discovery Telecon 2011-04-12

Logistics

So far, have been using a NASA MeetMe number. Next telecon will need to switch to ESIP's Webex number.

Schedule posted: Jluly 12-13 Summer Meeting, Santa Fe, NM
- Need to add slot for Discovery
- Interest in slot for Wednesday July_13,_2011 (Teacher Workshop, Technical Workshops, Plenary, Poster Session)
Discovery session topic ideas
- Overview of Discovery
  - Get everyone up to speed with discovery services.
  - Designated technical consultants for each area:
    - OpenSearch: Chris Lyness
    - ServiceCasting: Brian Wilson
    - Collection Casting: Ruth Duer
    - Services/Solr/Depoyment: Hook Hua
- Showcase of various clients (e.g. ServiceCasting or DataCasting)
  - more like outreach. demonstrate impact of cluster
  - 10-15 minutes each.
  - GES DISC (Mirador, Simple Subset Wizrd, and Community Based Giovanni)
  - NSIDC can also show interface
  - JPL DataCasting
  - ECHO? (latest multi-format client)
- Working Technical Session
  - Many folks have mixed feelings on need of technical session.

To help new infusion cases of Discovery services.
Example case: EPA (Bill Sonntag)
Possible title: "Getting started with ESIP Discovery Services"
- intended mainly for the techies.
- could even show again at ESIP.
Contribute slide content
- new wiki page Discovery Webinar Materials created to post content to.
- Ruth has some high-level slides for setting the ground work.
To be effective, need to cover service providers and clients.
Cover services for OpenSearch, ServiceCasting, and DataCasting
Show some existing applications.
Show power of mashups.
- Ruth at beginning stages of using DataCasting to feed aggregator for web portal

Interoperability
- Want to make sure that both service and client implementations adhere to the specification to ensure interoperability.
Any plans for existing and new implementations of Discovery service providers to follow the DCP-1 specification?
- ECHO (Matt) planning to update in next couple of months
- NSIDC (Ruth) planning to update in next iterations
- GES DISC (Richard) to assessment service updates
- WSNEWS (Hook) planning to update in next couple of months
- check with Brian on ServiceCasting.

Which ideas to formalize next?
Need motivators first to draft up specification documents and then handoff to facilitator for going through the DCP process.
New incubator ideas
- Ruth wants to propose OpenSearch for Services. Essentially using OpenSearch as ServiceCasting.
  - Using same OpenSearch Request interface for DataCasting and ServiceCasting.
  - need to post information on this on wiki.
- Hook wants to propose a JSON response format for the Discovery specs
  - should help to (1) increase development productivity and (2) increase efficiency of response--especially for non-pagination responses
Some existing ideas
- Specific extensions to Discovery Atom Response format for Granule-level, Collection-level, and Service responses. Simply builds upon DCP-1.
- Discovery RSS Response Format
- OpenSearch Request Format. adopt OGC OpenSearch spec.
- ServiceCasting Request Format
- DataCasting Request Format
- Mashup conventions
- Apache SOLR Request format
- Apache SOLR Response format
- Apache Nutch Opensearch RSS response format
- Custom Elements

What use(s) the Discovery cluster might be able to think of proposing. See Testbed.
If we have applications that are portable, can put on the testbed.
- e.g. drop down portable OpenSearch server
Want to test server implementation on the testbed.
Want to test clients.
Products and Services proposal for test bed activities. some funding available.
- Discovery cluster could also contribute to the testbed proposal. Hook to write up addition and email Ken.
testbed could also be used to test out new reference implementations of DCP specifications.
- allows for clients to test interoperability and compliance.
