Integrating ISO Metadata into HDF Data Products
Many communities are working to improve their data documentation through the use of ISO metadata standards. The HDF Group is working to facilitate the use of ISO in HDF. The HDF Product Designer (https://wiki.earthdata.nasa.gov/display/HPD/HDF+Product+Designer) helps users define metadata and file structures for data products in the Hierarchical Data Format. We will describe and demonstrate current Product Designer capabilities and explore approaches to integrating ISO metadata into product designs. Two NASA use cases will be presented.
