| + * Ilkay |
| + ** Looking into RBNB and Antelope docs to determine the access API |
| + ** Been working on a Kepler stream actor to get RBNB from NEON stream testbed |
| + ** Aiming for NEON TDR meeting on April 29 |
| + *** Adapting code from Peter Shin @ NEON that had been used for storing data in relational db |
| + |
| + * Nathan |
| + ** 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 |
