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
