Update (and future plans) on CADIS • the next generation portal, a gateway now, is under development • it should be in beta by October • should go live in December, replacing the present portal • the gateway will have enhanced search capabilities • no longer will rely on a hierarchical structure for finding data • metadata will reside in two databases • THREDDS catalogs will be generated as needed from the PostgreSQL database, similar to the way EOL has been doing it for the CDP • searches will use the RDF (Resource Description Framework)Triple Store database • queries short statements in the form of subject-predicate-object • for both text and geospatial searches
Update (and future plans) on CADIS • the present CADIS metadata profile will continue to define data sets • metadata can come into the databases and gateway through several routes • metadata input form • same as present portal • changes to it may be made after gateway has been live for a while • DIF or other XML file uploaded to gateway • OAI-PMH harvesting of other data repositories • THREDDS catalogs • ARMAP and ARLISS (various web services)
Update (and future plans) on CADIS • the ingest of existing THREDDS catalogs will be used to initially populate the gateway • a one-time operation • need to make sure all metadata is represented in the present THREDDS catalogs before ingest • no file level metadata have been defined for CADIS, yet, nor collected • need to extend the metadata input interface to include file level metadata for search, visualization and other planned services • need site information in the database for mapping and searching • lat/lon information for sites has been entered into the mapserver, and shared with the gateway team
