ECS Metadata & HDF-EOS

• ECS Metadata are written as User-defined HDF global attributes:



• coremetadata.n {where n = 0,...9; maximum 64 K each}

• Data Providers may include other metadata blocks:

  • archivedmetadata.n {where n = 0,...9 ; maximum 64 K each}
  • <user_defined_name>.n {where n = 0,...9 ; maximum 64 K each}

• HDF Library calls are used to retrieve metadata blocks:

• SDstart
• SDfindattr
• SDattrinfo
• SDreadattr
