What: ESIP 2012 Winter meeting, Discovery Workshop.
- This is the first of two Discovery sessions. See our other planning session on Friday.
When: Thursday, January 5, 2012 at 2:00pm-3:30pm. Track 3.
Where: Renaissance Washington, DC Dupont Circle Hotel, Room: MT. VERNON
Description: The set of ESIP Discovery services encompass the overlapping conventions of Earth science federated OpenSearch, Collection Casting, Granule Casting, and Service Casting feed standards. This workshop will cover some technical discussions of how Discovery services and specifications can be practically applied to facilitate collaborations by enabling sharing of services and data.
Session Lead(s): Chris Lynnes, Hook Hua
ESIP Collaboration Areas: Discovery
Expertise Level: Apprentice
Topic tags: Tech
Note: This session is focused on making progress as a community in coordinating conventions and interoperability of discovery services.

Slides on "OGC and ESIP Discovery, OR Can't we all just get along??"
OGC proposing OpenSearch specification.
we need to converge with OGC specification as much as possible.
OGC's approaches are intended to be compatible with the mass-market
Key Differences in Atom Response
- time
  - ESIP: OpenSearch time request extension adopted to response.
  - OGC: dc:date, which is soft type and schema-less
- link identification
to determine best approach to link identification, best to identify first the key issues trying to solve.
Link identification approaches
- DCP-1
  - to be deprecated
- DCP-2
  - withdrawn
- DCP-3
  - under debate
  - return IANA rel + ESIP-specific attributes
  - OGC had a problem with this approach since ignored by mass-market tools.
- mime-type
  - IANA rel + extend type
  - primary and secondary type delimited with "+" is formally supported in mime-type values.
  - mime-types also support services via "application/" prefix.
- "DCP-3"-style + mime-type combined approach

 === Interoperability for OpenSearch in various types of casting (45-minutes, Brian Wilson and Ruth Duerr) ===
 * e.g., forming relations between casts
