   As it maps to
       Dublin Core
                       What is Interoperability?

• It is people, standards, and machines that
  understand each other
• It is all about breaking down the barriers and
  silos
• It is not complicated to achieve, but it does
  require commitment and perseverance
• Is it desirable?
  …….. you tell us!

People
   • the will to make interoperability a reality
Standards
   • data, metadata, web services
Nuts and Bolts
   • distributed network
   • Internet/Intranet
   • development, testing, and deployment
   • integrated search environment
   • enabling tools

                                 Enable Interoperability
Metadata Standards
   • international standards complement science-based
     nature of Environment Canada
      •   FGDC - CSDGM
      •   FGDC - Biological Data Profile
      •   Station Level metadata
      •   Dublin Core
  • permits interoperability across diverse information
    holdings
  • permits horizontal integration of business processes
Controlled vocabularies
  • data owners use the same language which enables data
    alignment and exhange
  • searchers use the same language as data owners,
    which enables consistent discovery
                Locating the Repositories and
                     Searching the Metadata
FGDC CSDGM and the FGDC Biological Data Profile
• metadata generated exist in detailed
  repositories
• users need to know where to go in order to
  search repositories separately or
  simultaneously through a node (NBII node of
  FGDC Clearinghouse, Discovery portal, ..)
                 Searching the Metadata and
                   Locating the Repositories
For Dublin Core
• Government OnLine adopts Dublin Core as
  part of Common Look and Feel Standard
     • enables high level discovery of web
        resources
   … but what about all of the other
    types of information assets that
    are not web based?
                   Searching the Metadata and
                     Locating the Repositories
For Dublin Core
• desirable to develop high level repositories
  of scientific information/data holdings
     • enable high level discovery of data
       sources
     • alternate point of entry to specialized
       repositories for more detailed searching

• need to map FGDC CSDGM and Biological
  Data Profile elements to Dublin Core to
  make this happen
    • approximately 18 Dublin Core elements

 Is anyone else doing this?
  NBII ?
  University of Louisiana - CORC (Cooperative Online
     Resource Catalog) project to enhance access to
     Federal Geographic Data Committee (FGDC) data
     sets
       alternate clearinghouse model
       convert existing metadata to more widely used standards for
        inclusion in other clearinghouses

                     …should be interoperable
• Traditional searching is normally performed within
  each specific resource
   • time consuming, incomplete
• interoperability allows for searching across a
  multitude of resources - at the same time
   • made possible by use of metadata standards,
      protocols, and XML
• allows for searching at Discovery, Access, and Use
