Planning Meeting Summary of Approaches Discussed, Feb. 7-8, 2001
The following approaches for short-term implementation of the DAWG vision were discussed at the Feb. 7-8 meeting.
Identify collections that we would initially like to include in the DLESE collection and then address issues specific to these collections.
Identify a few use cases to frame the educational content and the datasets that should first be exploited.
Identifying the breadth of efforts currently underway and enabling communication and collaboration between groups.
Demonstration project linking a few distributed Earth data representing datasets from ocean, atmosphere, solid Earth, social and life sciences with a basic tool kit. Constructed and evaluated within one or more educational context.
Linking with related groups (nonearth scientists, mathematicians, physicists) and commonly used tool developers who would like access to Earth data in their presentations.
Demonstration focused on a small region showing in-depth development of tools and data access.
Develop automated package to construct datasets and learning resources around timely Earth events.
Developing underlying support structure for end-to-end delivery and use of datasets.
Enhance metadata framework for datasets and catalog existing datasets and learning resources using datasets.
Research on effective use of datasets in the classroom.
Encouraging the development of resources and services supporting end-to-end delivery.
Plan for sustainability and maintenance.
Explore dataspace and develop demonstration project that exercises a variety of data types.
Principles for Data Access through DLESE
To rely on partnerships for:
Follow patterns that reflect the state of the art
To gain early success:
- Place/feature specific data discovery
- Tool specific data discovery
- Data specific tool discovery
- Application-based viewing/analysis (thick client)
- Browser-based data viewing/analysis (thin client)
To aim for long-term success:
- Persistent identifiers
- Personalized data collections
- Middleware matching tools and data types
- Scalability limits on human-generated metadata
- Improved data access (remote, real-time, etc.)
- Facilitated data use (i.e., enhance useage metadata)
- Improved data discovery
