Convention Support
• Initial:• NetCDF User’s Guide (NUG)• Attribute Convention for Data Discovery (ACDD)• Object Convention for Data Discovery (OCDD)• Climate and Forecast (CF)• HDF-EOS
• Implementation:• Conventions for groups and variables• Convention for connected variables (e.g.
coordinate dimensions)• Compliance checkers on entire file
• Support for community components

Conclusion
• enable individuals and mission teams to design products quickly and easily
• enable collaboration at many levels• promote data management best practices
HDF Product Designer is being built using a flexible architecture to support multiple front and back ends. It will:
