1. Growing importance of metadata for synthetics: Calculating and Sharing Synthetic Seismic Data
Dogan Seber University of California, San Diego San Diego Supercomputer Center

2. Metadata: Two definitions
Used to refer to “attributes in data sets”
Used as “data about data: archival information for a data set following a certain standard (e.g, Dublin Core, FGDC)”

3. Challenges faced in a community-based synthetic seismogram calculations and exchange
Inaccessibility of software
Complexity of software
Lack of computational resources
Lack of reliable high resolution earth models
Lack of data exchange standards and metadata

4. What IT could offer … The Grid
Distributed computing environment (e.g., TeraGrid)
Seamless access to distributed data resources (e.g., GEON)
Service-based architecture design (e.g., Web services)
Metadata (in XML format?)
Attribute level
Archival/Librarian level

5. An Example from GEON
Grid-enabled synthetic seismogram calculation system for research and education
In collaboration with LLNL (Bill Glassley and Shawn Larsen)
Service-based access to resources and data
Sharable control files for reproducible calculations
Long term archival of results
