+ * __TODO__: Mark and Matt to upload edited documents to wiki
Line 29 was replaced by lines 31-47
- **
+ ** data models seem compatible -- looked at the Ptolemy model and there's a reasonable mapping between the types
+ *** fixed point type probably maps to a float
+ ** sequence is an ongoing problem
+ ** have to map grids, but will lose implied semantic information
+ *** grid is collection of arrays, main array with other arrays that specify, e.g., coordinates in lat and lon
+ *** need to try to maintain the implied relationship between these 3 arrays to ease processing
+ ** hasn't figured out how to implement an actor
+ *** __TODO__: Nathan work with Ilkay on actor
+ ** also need to map Common Data Model (CDM) and EML
+ *** [http://knb.ecoinformatics.org/software/eml/]
+ *** unifies HDF5, NetCDF4, OPeNDAP
+ *** much of the CDM has to deal with quirks of HDF5 focused on HPC access to data
+ *** __TODO__: Nathan develop a more formal mapping between the major data models
+ ** Peter: suggests Nathan, Peter, James propose a schedule for data model mapping description and implementation in Kepler
+
+ ! Next meeting: May 2, 2007 10:00 am pacific time
