Work Session 1: Comprehensive architecture design (all elements of architecture)

Working Session 2:  Architecture design with a focus on Federated Search  

A broad review of all aspects of architecture. Including but not limited to discussion of:

  • Community building, coordination, and governance,
  • Physical infrastructure,
  • Discovery and federated search
  • Implementation software
  • Standards and specifications
  • Exchange protocols for data
  • Semantic annotation and modeling for data

Open discussion to set priorities for this working group.
All members to share their two most pressing metadata challenges that limit inclusion in an overall metadata architecture. (Pip Bricher)

Potential topics include:

  • Discovery vs use metadata
  • Metadata granularity
  • Exchange protocols
  • Semantics/vocabularies for metadata
10:30 Break Break
10:50 Working Session 1 continued.  Identifying key components of the architecture

Working Session 2 continued: Open discussion (on topic(s) selected before the break)

12:30 Lunch  Lunch
13:30 Work Session 1 Work Session 2
  Summary of morning Working Sessions (presented by a representative of each session; 15 minutes per session.

Focus on semantic aspects of data sharing and implications for architecture design

Opportunities to collaborate with ASDI/Spatineo: Remote presentation by Sampo Savolainen

Open discussion

15:30 Break
  Comprehensive Architecture Design:  develop a data sharing architecture diagram/design and related narrative that describes a system that could serve one or more use cases. Wherever possible, this architecture will address challenges identified and utilize solutions identified in the previous sessions. Finalise the polar metadata catalogue survey and paper started at the Polar Data Planning Summit
