Data Management Office

• Make project data available on-line
• Hunting the data and information down
• Quality control
• Find and document the metadata
• Add data to the JGOFS/GLOBEC system
• Data are freely available must abide by data
  acknowledgment policy

Data Management Office

• Facilitate data access and synthesis
• JGOFS/GLOBEC data management system
• Data objects
• Directory structure
• Download capability
• Simple X-Y plotting
• Distributed data servers
• Software is open source, freely available
• DIF records submitted to the Global Change Master
  Directory

Key Data Policy Characteristics

• Dissemination to scientific investigators on a
  timely basis
• Available when "useful"
• Available to others outside the program

6
New DMO Efforts

• Implementing a geographical user interface to
• JGOFS/GLOBEC and additional features needed to
• improve interoperability with other data systems
• Geospatial (MapServer) interface
• XML encoding of metadata
• Open Geospatial Consortium access
• Web Mapping Service (WMS)
• Web Feature Service (WFS)

JGOFS/GLOBEC uses a text based interface

• Supports all web browsers
• Distributed servers for ASCII and image data
  using httpd protocol
• Simple, list oriented interface with basic X-Y
  plotting capabilities
