2. High level APIs
• Make HDF5 easier to use
– More operations per call than the normal HDF5 API
• Encourage standard ways to store objects

3. High level APIs
• Lite – done
– Same as HDF5, but simpler
• Image – done
– Interprets dataset as image/palette
– 2-D raster data like HDF4 raster images
• Table – partly done
– Interprets dataset as “tables” – collections of records
– Insert, delete records or fields
– Future: sort and search
• Dimension scale – in the works
• Unstructured grids – in the works
