The ingest activities in the RP focused on 1) modeling the metadata schema for ADL; 2) designing the ingest interface to the Sybase RDBMS, using Tcl/Tk; 3) entering records into the RP database, using 80 metadata fields.
The ingest activities in the WP are similar, with the following additions: 1) extending the metadata schema to include all FGDC fields, plus as many additional USMARC fields as are needed; 2) ingesting existing metadata sets, including approximately 450K frame-level records for a NASA air photo database, approximately 350K sheet-level records for map series (Geodex), and approximately 100K USMARC map records from MELVYL (the University of California online union catalog); 3) creating new catalog records for selected items, including Web sites for digital spatial data, and air photos for four local California counties; 4) moving the ingest interface from Sybase to Microsoft Access.
