update and future plans on cadis
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
